ExtraHop REST API Guide
Introduction to the ExtraHop REST API
The ExtraHop REST API enables you to automate administration and configuration tasks on your ExtraHop system. You can send requests to the ExtraHop API through a Representational State Transfer (REST) interface, which is accessed through resource URIs and standard HTTP methods.
Video: | See the related training: Rest API Overview |
Each ExtraHop system provides access to the built-in ExtraHop REST API Explorer, which enables you to view all of the available system resources, methods, properties, and parameters. The REST API Explorer also enables you to send API calls directly to your ExtraHop system.
Note: | This guide is intended for an audience that has a basic familiarity with software development and the ExtraHop system. |
ExtraHop API requirements
Before you can begin writing scripts for the ExtraHop REST API or performing operations through the REST API Explorer, you must meet the following requirements:
- Your ExtraHop system must be configured to allow API key generation for the type of user you are (remote or local).
- You must generate a valid API key.
- You must have a user account on the ExtraHop system with appropriate privileges set for the type of tasks you want to perform.
Access and authenticate to the ExtraHop REST API
Setup users and users with system and access administration privileges control whether users can generate API keys. For example, you can prevent remote users from generating keys or you can disable API key generation entirely. When this functionality is enabled, API keys are generated by users and can be viewed only by the user who generated the key.
Note: | Administrators set up user accounts and assign privileges, but then users generate their own API keys. Users can delete API keys for their own account, and users with system and access administration privileges can delete API keys for any user. For more information, see Users and user groups. |
After you generate an API key, you must append the key to your request headers. The following example shows a request that retrieves metadata about the firmware running on the ExtraHop system:
curl -i -X GET --header "Accept: application/json" \ --header "Authorization: ExtraHop apikey=2bc07e55971d4c9a88d0bb4d29ecbb29" \ "https://<hostname-or-IP-of-your-ExtraHop-system>/api/v1/extrahop"
Privilege levels
User privilege levels determine which ExtraHop system and administration tasks the user can perform through the ExtraHop REST API.
You can view the privilege levels for users through the granted_roles and effective_roles properties. The granted_roles property shows you which privilege levels are explicitly granted to the user. The effective_roles property shows you all privilege levels for a user, including those received outside of the granted role, such as through a user group.
The granted_roles and effective_roles properties are returned by the following operations:
- GET /users
- GET /users/{username}
The granted_roles and effective_roles properties support the following privilege levels. Note that the type of tasks for each ExtraHop system vary by the available resources listed in the REST API Explorer and depend on the modules enabled on the system and user module access privileges.
Privilege level | Actions allowed |
---|---|
"system": "full" |
|
"write": "full" |
|
"write": "limited" |
|
"write": "personal" |
|
"metrics": "full" |
|
"metrics": "restricted" |
|
"ndr": "full" |
This is a module access privilege that can be granted to a user in addition to one of the following system access privilege levels:
|
"ndr": "none" |
This is a module access privilege that can be granted to a user in addition to one of the following system access privilege levels:
|
"npm": "full" |
This is a module access privilege that can be granted to a user in addition to one of the following system access privilege levels:
|
"npm": "none" |
This is a module access privilege that can be granted to a user in addition to one of the following system access privilege levels:
|
"packets": "full" |
This is an add-on privilege that can be granted to a user with one of the following privilege levels:
|
"packets": "full_with_keys" |
This is an add-on privilege that can be granted to a user with one of the following privilege levels:
|
"packets": "slices_only" |
This is an add-on privilege that can be granted to a user with one of the following privilege levels:
|
Manage API key access
Users with system and access administration privileges can configure whether users can generate API keys for the ExtraHop system. You can allow only local users to generate keys, or you can also disable API key generation entirely.
- Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
- In the Access Settings section, click API Access.
-
In the Manage API Access section, select one of the
following options:
- Allow all users to generate an API key: Local and remote users can generate API keys.
- Only local users can generate an API key: Remote users cannot generate API keys.
- No users can generate an API key: No API keys can be generated by any user.
- Click Save Settings.
Generate an API key
You must generate an API key before you can perform operations through the ExtraHop REST API. Keys can be viewed only by the user who generated the key or by users with system and access administration privileges. After you generate an API key, add the key to your request headers or the ExtraHop REST API Explorer.
Before you begin
Make sure the ExtraHop system is configured to allow API key generation.- In the Access Settings section, click API Access.
- In the Generate an API Key section, type a description for the new key, and then click Generate.
- Scroll down to the API Keys section and copy the API key that matches your description.
Configure cross-origin resource sharing (CORS)
Cross-origin resource sharing (CORS) allows you to access the ExtraHop REST API across domain-boundaries and from specified web pages without requiring the request to travel through a proxy server.
- Log in to the Administration settings on the ExtraHop system through https://<extrahop-hostname-or-IP-address>/admin.
- In the Access Settings section, click API Access.
-
In the CORS Settings section, specify one of the following
access configurations.
- To add a specific URL, type an origin URL in the text box, and then
click the plus (+) icon or press ENTER.
The URL must include a scheme, such as HTTP or HTTPS, and the exact domain name. You cannot append a path; however, you can provide a port number.
- To allow access from any URL, select the Allow API requests
from any Origin checkbox.
Note: Allowing REST API access from any origin is less secure than providing a list of explicit origins.
- To add a specific URL, type an origin URL in the text box, and then
click the plus (+) icon or press ENTER.
- Click Save Settings and then click Done.
Set up an SSL certificate
Before making requests to an ExtraHop system with a self-signed certificate, you must set up an SSL certificate for each user who will access the ExtraHop system from a particular computer.
In each of the following examples, replace {HOST} with the hostname of your ExtraHop system.
Note: | The SSL certificate applies only to the user performing the command. Each user must run the command with their login credentials to set up the SSL certificate. |
Learn about the REST API Explorer
The REST API Explorer is a web-based tool that enables you to view detailed information about the ExtraHop REST API resources, methods, parameters, properties, and error codes. Code samples are available in Python, cURL, and Ruby for each resource. You also can perform operations directly through the tool.
Open the REST API Explorer
You can open the REST API Explorer from the Administration settings or through the following URL:
https://<extrahop-hostname-or-ip-address>/api/v1/explore/
View operation information
From the REST API Explorer, you can click any operation to view configuration information for the resource.
The following table provides information about the sections available for resources in the REST API Explorer. Section availability varies by HTTP method. Not all methods have all of the sections listed in the table.
Section | Description | ||
---|---|---|---|
Body Parameters | Provides all of the fields for the request body and supported values for each field. | ||
Parameters | Provides information about the available query parameters. | ||
Responses | Provides information about the possible HTTP status
codes for the resource. If you click Send Request, this
section also includes the response from the server and the cURL, Python, and Ruby
syntax required to send the specified request.
|
Identify objects on the ExtraHop system
To perform API operations on a specific object, you must locate the object ID. You can easily locate the object ID through the following methods in the REST API Explorer.
- The object ID is provided in the headers returned from a POST request. For example, if you
send a POST request to create a page, the response headers display a location URL.
The following request returned the location for the newly created tag as /api/v1/tags/1 and the ID for the tag as 1.
{ "date": "Tue, 09 Nov 2021 18:21:00 GMT ", "via": "1.1 localhost", "server": "Apache", "content-type": "text/plain; charset=utf-8", "location": "/api/v1/tags/1", "cache-control": "private, max-age=0", "connection": "Keep-Alive", "keep-alive": "timeout=90, max=100", "content-length": "0" }
- The object ID is provided for all objects returned from a GET request. For example, if you
perform a GET request on all devices, the response body contains information for
each device, including the ID.
The following response body displays an entry for a single device, with an ID of 10212:
{ "mod_time": 1448474346504, "node_id": null, "id": 10212, "extrahop_id": "test0001", "description": null, "user_mod_time": 1448474253809, "discover_time": 1448474250000, "vlanid": 0, "parent_id": 9352, "macaddr": "00:05:G3:FF:FC:28", "vendor": "Cisco", "is_l3": true, "ipaddr4": "10.10.10.5", "ipaddr6": null, "device_class": "node", "default_name": "Cisco5", "custom_name": null, "cdp_name": "", "dhcp_name": "", "netbios_name": "", "dns_name": "", "custom_type": "", "analysis_level": 1 },
ExtraHop API resources
You can perform operations on the following resources through the ExtraHop REST API. You also can view more detailed information about these resources, such as available HTTP methods, query parameters, and object properties in the REST API Explorer.
Activity Map
An activity map is a dynamic visual representation of the L4-L7 protocol activity between devices in your network. Create a 2D or 3D layout of device connections in real-time to learn about the traffic flow and relationships between devices.
Here are some important considerations about activity maps:
- You can only create activity maps for devices in Standard Analysis and Advanced Analysis. Discovery Mode devices are not included in activity maps. For more information, see Analysis levels.
- If you create an activity map for a device, activity group, or device group with no protocol activity in the selected time interval, the map appears without any data. Change the time interval or your origin selection and try again.
- You can create an activity map in a console to view device connections across all of your sensors.
To learn about configuring and navigating activity maps, see Activity maps.
The following table displays all of the operations you can perform on this resource:
Operation | Description |
---|---|
GET /activitymaps | Retrieve all activity maps. |
POST /activitymaps | Create a new activity map. |
POST /activitymaps/query | Perform a network topology query, which returns activity map data in flat file content. |

Analysis Priority
The ExtraHop system analyzes and classifies traffic for every device it discovers. Your license reserves capacity for the ExtraHop system to collect metrics for high value devices. This capacity is associated with two analysis levels: Advanced Analysis and Standard Analysis.
You can specify which devices receive Advanced Analysis and Standard Analysis levels by configuring analysis priority rules. Analysis priorities help inform the ExtraHop system about which devices are important in your environment. A third analysis level, Discovery Mode, is available for devices that are not in Advanced or Standard Analysis.
Note: | By default, each sensor manages its own analysis priorities. If the sensor is connected to a console, you can centrally manage these shared system settings from the console. |

Operand values for detection property tuning rules
The POST /detections/rules/hiding operation enables you to create tuning rules that filter detections based on detection properties. You can specify filtering criteria for detection properties in objects. Each object should contain a unique value for the operand field that is valid for the specified property value.
Tip: | You can retrieve valid property values through the GET
/detections/formats operation. See the keys of the
properties object in the response. In the following example,
the property value is s3_bucket:
"properties": { "s3_bucket": { "is_optional": true, "status": "active", "is_tunable": true, "data_type": "string" } } The is_tunable field indicates whether you can create a tuning rule based on the property. |
registered_domain_name
To hide rules by a registered domain name, specify the property value as registered_domain_name and the operand value as a domain name.
The following example rule hides DNS Tunnel detections for example.com.
{ "detection_type": "dns_tunnel", "expiration": null, "offender": "Any", "victim": "Any", "properties": [ { "operand": "example.com", "operator": "=", "property": "registered_domain_name" } ] }
uris
To hide rules by a URI, specify the property value as uris and the operand value as a URI.
The following example rule hides SQL Injection (SQLi) Attack detections for http://example.com/test.
{ "detection_type": "sqli_attack", "expiration": null, "offender": "Any", "victim": "Any", "properties": [ { "operand": "http://example.com/test", "operator": "=", "property": "uris" } ] }
top_level_domain
To hide rules by a top-level domain name, specify the property value as top_level_domain and the operand value as a top-level domain name.
The following example rule hides Suspicious Top-level Domain detections for the org top-level domain.
{ "detection_type": "suspicious_tld", "expiration": null, "offender": "Any", "victim": "Any", "properties": [ { "operand": "org", "operator": "=", "property": "top_level_domain" } ] }
Search with regular expressions (regex)
For certain property values, the string can be in regex syntax. Specify the operand value as an object that has a value parameter with the regex syntax you want to match and an is_regex parameter that is set to true. The following rule filters DNS Tunnel detections with domain names that end with example.com.
{ "detection_type": "dns_tunnel", "expiration": null, "offender": "Any", "victim": "Any", "properties": [ { "operand": { "value": ".*?example.com", "is_regex": true }, "operator": "=", "property": "registered_domain_name" } ] }
Disable case sensitivity
By default, searches for string property values are case-sensitive. However, you can disable case sensitivity by specifying the operand value as an object that has a case_sensitive parameter that is set to false.
The following rule hides Hacking Tool Domain Access detections with the ArchStrike hacking tool.
{ "detection_type": "hacking_tools", "expiration": null, "offender": "Any", "victim": "Any", "properties": [ { "operand": { "value": "archstrike", "case_sensitive": false }, "operator": "=", "property": "hacking_tool" } ] }

Metrics
Metrics information is collected about every object identified by the ExtraHop system.
Note that metrics are retrieved through the POST method, which creates a query to collect the requested information through the API. For more information, see Extract metrics through the REST API.
The following table displays all of the operations you can perform on this resource:
Operation | Description | ||
---|---|---|---|
POST /metrics | Retrieves metrics for each specified object. | ||
GET /metrics/next/{xid} | If you request metrics from a console with the
POST /metrics, POST /metrics/total, or
POST /metrics/totalbyobject operation, and you specify objects that
have been observed by multiple sensors, the response contains the xid
field, rather than metric data. You can retrieve metric data by specifying the
xid field in the GET /metrics/next/{xid}
operation, which returns metrics from one of the sensors connected to the
console. Repeat the GET /metrics/next/{xid} operation to return metrics from additional sensors. After all metrics are retrieved, the operation returns null. If metrics are not yet available from the sensor, the string again is returned. Wait a few seconds and then try again.
|
||
POST /metrics/total | Retrieves combined metric totals for all specified objects. | ||
POST /metrics/totalbyobject | Retrieves metric totals for each specified object. |
For example, the following request body retrieves HTTP responses that two devices sent over the last 30 minutes.
{ "cycle": "auto", "from": -1800000, "metric_category": "http_server", "metric_specs": [ { "name": "rsp" } ], "object_ids": [ 180, 177 ], "object_type": "device", "until": 0 }
For the POST /metrics operation, the previous example request body returns counts of HTTP responses that occurred during each time interval, labeled with the time of each event and the ID of the device that sent the responses, similar to the following example response:
{ "cycle": "30sec", "node_id": 0, "clock": 1709659320000, "from": 1709657520000, "until": 1709659320000, "stats": [ { "oid": 177, "time": 1709657520000, "duration": 30000, "values": [ 4 ] }, { "oid": 177, "time": 1709657550000, "duration": 30000, "values": [ 4 ] }, { "oid": 180, "time": 1709657520000, "duration": 30000, "values": [ 4 ] }, { "oid": 180, "time": 1709657550000, "duration": 30000, "values": [ 4 ] } ] }
For the POST /metrics/totalbyobject operation, the same previous example request body retrieves the combined total for each device over the entire time period, similar to the following example response:
{ "cycle": "30sec", "node_id": 0, "clock": 1709659620000, "from": 1709657820000, "until": 1709659620000, "stats": [ { "oid": 180, "time": 1709659620000, "duration": 1830000, "values": [ 8 ] }, { "oid": 177, "time": 1709659620000, "duration": 1830000, "values": [ 8 ] } ] }
For the POST /metrics/total operation, the same previous example request body retrieves the combined total of both devices over the entire time period, similar to the following example response:
{ "cycle": "30sec", "node_id": 0, "clock": 1709659830000, "from": 1709658030000, "until": 1709659830000, "stats": [ { "oid": -1, "time": 1709659830000, "duration": 1830000, "values": [ 16 ] } ] }
Note that the behavior of the /metrics/total and /metrics/totalbyobject endpoints depends on the type of the metric. For count metrics, the values field contains a sum total of values over the specified time interval, as shown in the example above. However, for dataset metrics, the values field contains a list of values and the frequency that those values appeared. For example, a query for server processing times with the POST /metrics/total operation returns a response similar to the following example:
{ "cycle": "30sec", "node_id": 0, "clock": 1494541440000, "from": 1494539640000, "until": 1494541440000, "stats": [ { "oid": -1, "time": 1494541380000, "duration": 1800000, "values": [ [ { "value": 2.271, "freq": 5 }, { "value": 48.903, "freq": 1 } ] ] } ] }
If there are more than 1,000 distinct dataset values over the specified time period, similar values are consolidated to reduce the response to 1,000 values. For example, if there are less than 1,000 values, the response might contain the following entries:
{ "value": 2.571, "freq": 4 }, { "value": 2.912, "freq": 2 }
However, if the response contains more than 1,000 values, those entries might be consolidated into the following entry:
{ "value": 2.571, "freq": 6 }
If the calc_type field is specified and the response contains more than 1,000 values, the percentile or mean is calculated according to the consolidated dataset.

The following table displays all of the operations you can perform on this resource:
Operation | Description |
---|---|
GET /packets/search | Search for packets by specifying parameters in a URL. |
POST /packets/search | Search for packets by specifying parameters in a JSON string. |
Operation details
GET /packets/search
Specify the following parameters.
- output: String
- (Optional) The output format.
* `pcap` - A PCAP file that contains packets.
* `keylog_txt` - A keylog text file that contains secrets for decryption.
* `pcapng` - A PCAPNG file that can contain both packets and secrets for decryption.
* `zip` - A ZIP file that contains both a PCAP and keylog text file.
* `extract` - A ZIP file that contains files extracted from packets that matched the query. This option is valid only if you have full access to the NDR module.
The following values are valid:
- pcap
- keylog_txt
- pcapng
- zip
- extract
- include_secrets: Boolean
- (Optional) Specifies whether to include secrets in the PCAPNG file. This option is valid only if `output` is set to `pcapng`.
- decrypt_files: Boolean
- (Optional) Specifies whether to decrypt extracted files with stored secrets. This option is valid only if the `output` parameter is `extract`.
- limit_bytes: String
- (Optional) The approximate maximum number of bytes to return. After the ExtraHop system finds packets that match the size specified in the search criteria, the system stops searching for additional packets. However, because the system analyzes multiple packets at a time, the total size of the packets returned might be larger than the specified size. The default unit is bytes, but you can specify other units with a unit suffix. The default value is "100MB". **Note**: If the output is "extract", there is a maximum value for this field. The default maximum is "100MB", but the maximum can be modified in the running configuration. If the output is not "extract", there is no maximum value.
- limit_search_duration: String
- (Optional) The approximate maximum amount of time to perform the packet search. After the specified amount of time has passed, the ExtraHop system stops searching for additional packets. However, the system will extend past the specified time to finish analyzing packets that were being searched before the time expired, and the system analyzes multiple packets at a time. Therefore, the search might last longer than the specified time. The default unit is milliseconds, but other units can be specified with a unit suffix. See the REST API Guide for supported time units and suffixes. The default value is "5m". **Note**: If the output is "extract", there is a maximum value for this field. The default maximum is "5m", but the maximum can be modified in the running configuration. If the output is not "extract", there is no maximum value.
- always_return_body: Boolean
- (Optional) Specifies the behavior if the query does not match any packets or if the packets matched by the query do not contain any files. If the value is true, the system returns an empty file and a 200 status code. If the value is false, the system returns a 204 status code but does not return a file.
- from: String
- The beginning timestamp of the time range the search will include, expressed in milliseconds since the epoch. A negative value specifies that the search will begin with packets captured at a time in the past. For example, specify -10m to begin the search with packets captured 10 minutes before the time of the request. Negative values can be specified with a time unit other than milliseconds, such as seconds or hours. See the REST API Guide for supported time units and suffixes.
- until: String
- (Optional) The ending timestamp of the time range the search will include, expressed in milliseconds since the epoch. A 0 value specifies that the search will end with packets captured at the time of the search. A negative value specifies that the search will end with packets captured at a time in the past. For example, specify -5m to end the search with packets captured 5 minutes before the time of the request. Negative values can be specified with a time unit other than milliseconds, such as seconds or hours. See the REST API Guide for supported time units and suffixes.
- bpf: String
- (Optional) The Berkeley Packet Filter (BPF) syntax for the packet search. For more information about BPF syntax, see the REST API Guide.

- decrypt_files: Boolean
- (Optional) Specifies whether to decrypt extracted files with stored secrets. This option is valid only if the `output` parameter is `extract`.
- limit_bytes: String
- (Optional) The approximate maximum number of bytes to return. After the ExtraHop system finds packets that match the size specified in the search criteria, the system stops searching for additional packets. However, because the system analyzes multiple packets at a time, the total size of the packets returned might be larger than the specified size.

Filter packets with Berkeley Packet Filter syntax
Search for packets with the Berkeley Packet Filter (BPF) syntax alone, or in combination with the built-in filters.
Berkeley Packet Filters are a raw interface to data link layers and are a powerful tool for intrusion detection analysis. The BPF syntax enables users to write filters that quickly drill down on specific packets to see the essential information.
The ExtraHop system constructs a synthetic packet header from the packet index data and then runs the BPF syntax queries against the packet header to ensure that queries are much faster than scanning the full packet payload. Note that ExtraHop supports only a subset of the BPF syntax. See Supported BPF syntax.
The BPF syntax consists of one or more primitives preceded by one or more qualifiers. Primitives usually consist of an ID (name or number) preceded by one or more qualifiers. There are three different kinds of qualifiers:
- type
- Qualifiers that indicate what type the ID name or number refers to. For example, host, net, port, and portrange. If there is no qualifier, host is assumed.
- dir
- Qualifiers that specify a particular transfer direction to and or from an ID. Possible directions are src, dst, src and dst, and src or dst. For example, dst net 128.3.
- proto
- Qualifiers that restrict the match to the particular protocol. Possible protocols are ether, ip, ip6, tcp, and udp.
Supported BPF syntax
The ExtraHop system supports the following subset of the BPF syntax for filtering packets.
Note: |
|
Primitive | Examples | Description |
---|---|---|
[src|dst] host <host ip> | host 203.0.113.50 dst host 198.51.100.200 |
Matches a host as the IP source, destination, or either. These host expressions can be specified in conjunction with other protocols like ip, arp, rarp or ip6. |
ether [src|dst] host <MAC> | ether host 00:00:5E:00:53:00 ether dst host 00:00:5E:00:53:00 |
Matches a host as the Ethernet source, destination, or either. |
vlan <ID> | vlan 100 | Matches a VLAN. Valid ID numbers are 0-4095. VLAN priority
bits are zero. If the original packet had more than one VLAN tag, the synthetic packet the BPF matches against will only have the innermost VLAN tag. |
[src|dst] portrange <p1>-<p2>
or [tcp|udp] [src|dst] portrange <p1>-<p2> |
src portrange 80-88 tcp dst portrange 1501-1549 |
Matches packets to or from a port in the given range. Protocols can be applied to a port range to filter specific packets within the range. |
[ip|ip6][src|dst] proto <protocol> | proto 1 src 10.4.9.40 and proto ICMP ip6 and src fe80::aebc:32ff:fe84:70b7 and proto 47 ip and src 10.4.9.40 and proto 0x0006 |
Matches IPv4 or IPv6 protocols other than TCP and UDP. The protocol can be a number or name. |
[ip|ip6][tcp|udp] [src|dst] port <port> | udp and src port 2005 ip6 and tcp and src port 80 |
Matches IPv4 or IPv6 packets on a specific port. |
[src|dst] net <network> | dst net 192.168.1.0 src net 10 net 192.168.1.0/24 |
Matches packets to or from a source or destination or either, that reside in a
network. An IPv4 network number can be specified as one of the following values:
|
[ip|ip6] tcp tcpflags & (tcp-[ack|fin|syn|rst|push|urg|) | tcp[tcpflags] & (tcp-ack) !=0 tcp[13] & 16 !=0 ip6 and (ip6[40+13] & (tcp-syn) != 0) |
Matches all packets with the specified TCP flag |
Fragmented IPv4 packets (ip_offset != 0) | ip[6:2] & 0x3fff != 0x0000 | Matches all packets with fragments. |

Operation details
POST /records/search
Specify the following parameters.
- body: Object
- The record log query.
- from: Number
- The beginning timestamp of the time range the query will search, expressed in milliseconds since the epoch. A negative value specifies that the search will begin with records created at a time in the past. For example, specify -600000ms to begin the search with records created 10 minutes before the time of the request. Negative values can be specified with a time unit other than milliseconds, such as seconds or hours. See the REST API Guide for supported time units and suffixes.
- until: Number
- The ending timestamp of the time range the query will search, expressed in milliseconds since the epoch. A 0 value specifies that the search will end with records created at the time of the request. A negative value specifies that the search will end with records created at a time in the past. For example, specify -300000ms to end the search with records created 5 minutes before the time of the request. Negative values can be specified with a time unit other than milliseconds, such as seconds or hours. See the REST API Guide for supported time units and suffixes.
- types: Array of Strings
- (Optional) An array of one or more record formats. The query returns only records that match the specified formats. If no value is specified, the query returns records of any type. Valid values for this field are displayed in the Record Type field on the Record Formats page. For example: "~cifs".
- limit: Number
- The maximum number of records returned by the query. The maximum value cannot exceed 10000. The default value is 100.
- offset: Number
- The number of records to skip in the query results. The query will return records starting from the offset value. This parameter is often combined with the limit and sort parameters. The default value is 0. For ExtraHop recordstores, the maximum value is 10,000; to retrieve records returned after the first 10,000, see POST /records/cursor/. For third-party recordstores, there is no maximum value.
- sort: Array of Objects
- The list of one or more sort objects that specify sort priorities. The returned records are sorted in the order the objects are listed. The parameters are defined under the sort_item section below. If no sort_item values are provided, records are sorted by timestamp in descending order.
- field: String
- The field name that returned records are sorted by.
- direction: String
- The order in which returned records are sorted. The default order is descending. After all other sorting criteria are applied, or if no sorting criteria was specified, the default order is descending by timestamp.
The following values are valid:
- asc
- desc
- filter: Object
- The object containing the parameters that specify the filter criteria. The parameters are defined under the filter section below. If no filter values are provided, the query returns all records that match the time range and any specified record formats.
- field: String
- The name of the field in the record to be filtered. The query compares the contents of the field parameter to the value of the operand parameter. If the specified field name is ".any", the union of all field values will be searched. If the specified field name is ".ipaddr" or ".port", the client, server, sender, and receiver roles are included in the search. Field names are located in record formats that can be viewed in the ExtraHop system.
- operator: String
- The compare method applied when matching the operand value against the field contents. All filter objects require an operator.
The following values are valid:
- >
- <
- <=
- >=

- ~
- !~
- and
- or
- not
- exists
- not_exists
- in
- not_in
- operand: String or Number or Object
- The value that the query attempts to match. The query compares the value of the operand to the contents of the field parameter and applies the compare method specified by the operator parameter. You can explicitly specify the operand data type as described in the REST API Guide.
- rules: Array of Objects
- The list of one or more filter objects within a single filter object. Filter objects can be embedded recursively. Only "and", "or", and "not" operators are allowed for this parameter.
- context_ttl: Number
- The amount of time to keep the search context active. The specified value is interpreted as a duration into the future. The default unit is milliseconds, but other units can be specified with a unit suffix. See the REST API Guide for supported time units and suffixes. If a non-null value is specified, the response includes a cursor ID that is accepted by POST /records/cursor/. This parameter is not supported for third-party recordstores.
Specify the body parameter in the following JSON format.
{ "context_ttl": 0, "filter": { "field": "string", "operator": "string", "operand": "string", "rules": [] }, "from": 0, "limit": 0, "offset": 0, "sort": { "field": "string", "direction": "string" }, "types": [], "until": 0 }
POST /records/cursor
Specify the following parameters.
- body: Object
- The cursor ID that specifies the next page of results in the query.
- cursor: String
- The unique identifier of the cursor that specifies the next page of results in the query.
Specify the body parameter in the following JSON format.
{ "cursor": "string" }
- context_ttl: Number
- (Optional) The amount of time to keep the search context active, expressed in milliseconds.
GET /records/cursor/{cursor}
Specify the following parameters.
- cursor: String
- The cursor ID.
- context_ttl: Number
- (Optional) The amount of time to keep the search context active, expressed in milliseconds.
If the request is successful, the ExtraHop system returns an object in the following format.
{ "cursor": "string", "from": 0, "records": {}, "total": 0, "until": 0, "warnings": {} }
Operand values in record queries
The operand field in the POST /records/search method specifies the value that a record query attempts to match. You can specify either the value only or both the data type and the value. If you specify only the value, the query will refer to the record format associated with the field parameter to determine the data type of the value.
The following example explicitly specifies the data type and value of the operand:
{ "from": -1000, "filter": { "field" : "senderAddr", "operator": "=", "operand" : { "type" : "ipaddr4", "value": "1.2.3.4" } } }
The following example specifies only the value of the operand:
{ "from": -1000, "filter": { "field" : "senderAddr", "operator": "=", "operand" : "1.2.3.4" } }
You can explicitly specify the following data types in the operand field:
- application
- boolean
- device
Note: You must specify the discovery ID of the device in the value field. You can find the discovery ID of a device through the POST /devices/search operation. - device_filter
- device_group
- flowinterface
- flownetwork
- ipaddr4
- ipaddr6
- number
- network_locality
- object
- string
The operand field supports CIDR notation when filtering by IP addresses; the operator field must be set to "=" or "!=".
{ "filter": { "operator": "and", "rules": [ { "field": "method", "operand": "SMB2_READ", "operator": "=" }, { "field": "reqL2Bytes", "operand": "100", "operator": ">" } ] }, "types": [ "~cifs" ], "from": "-30m" }
Query records with a device group filter
To filter records by device group in the REST API, you must send a POST request to the /records/search endpoint with a record query filter that meets the following criteria:
- The field must specify devices, such as client, server, sender, or receiver.
- The operator must be either in or not_in.
- The operandtype must be device_group.
- The operandvalue must be a string representation of the numerical device group ID. You can retrieve device group IDs by running the GET /devicegroup operation and viewing the contents of the id field in the response.
For example, the following query searches for records in which the client device was a member of a device group with an ID of 200:
{ "from": "-30m", "filter": { "field": "client", "operator": "in", "operand": { "type": "device_group", "value": "200" } } }
You can also filter records by device group criteria without creating a device group by specifying the operand type as device_filter. For example, the following query searches for records in which the client device is running Windows 10:
{ "from": "-30m", "filter": { "field": "client", "operator": "in", "operand": { "type": "device_filter", "value": { "field": "software", "operand": "windows_10", "operator": "=" } } } }
Note: | Operand values with type device_filter for record search are formatted the same as device search filters. For more information, see Operand values for device groups. |
Query records with a network locality filter
To filter records by device group in the REST API, you must send a POST request to the /records/search endpoint with a record query filter that meets the following criteria:
- The field must be a record field that specifies an IP address such as clientAddr, serverAddr, senderAddr, or receiverAddr.
- The operator must be either in or not_in.
- The operand type must be network_locality.
- The operand value must be a string representation of a numerical network locality ID. You can view locality IDs with the GET /networklocalities operation.
For example, the following query searches for records where the client device is in a network locality with an ID of 123:
{ "from": "-30m", "filter": { "field": "clientAddr", "operand": { "type": "network_locality", "value": "123" }, "operator": "in" } }
Supported time units
For most parameters, the default unit for time measurement is milliseconds. However, the following parameters return or accept alternative time units such as minutes and hours:
- Device
- active_from
- active_until
- Device group
- active_from
- active_until
- Metrics
- from
- until
- Record Log
- from
- until
- context_ttl
The following table displays supported time units:
Time unit | Unit suffix |
---|---|
Year | y |
Month | M |
Week | w |
Day | d |
Hour | h |
Minute | m |
Second | s |
Millisecond | ms |
To specify a time unit other than milliseconds for a parameter, append the unit suffix to the value. For example, to request devices active in the last 30 minutes, specify the following parameter value:
GET /api/v1/devices?active_from=-30m
The following example specifies a search for HTTP records created between 1 and 2 hours ago:
{ "from": "-2h", "until": "-1h", "types": ["~http"] }
Report
A report is a PDF file of a dashboard that you can schedule for email delivery to one or more recipients. You can specify how often the report email is delivered and the time interval for dashboard data included in the PDF file.
Important: | You can only schedule reports from an ECA VM. |
Here are some important considerations about dashboard reports:
- You can only create a report for dashboards that you own or have been shared with you. Your ability to create a report is determined by your user privileges. Contact your ExtraHop administrator for help.
- Each report can only link to one dashboard.
- If you created a report for a dashboard that was later deleted or became inaccessible to you, the scheduled email will continue to be sent to recipients. However, the email will not include the PDF file and will instead notify recipients that the dashboard is unavailable to the report owner.
The following table displays all of the operations you can perform on this resource:
Operation | Description |
---|---|
GET /reports | Retrieve all reports. |
POST /reports | Create a report. |
DELETE /reports/{id} | Delete a specific report. |

Watchlist
To guarantee that an asset, such as an important server, database, or laptop, is guaranteed Advanced Analysis, you can add that device to the watchlist.
Tip: | If you want to add several devices to the watchlist, consider creating a device group and then prioritizing that group for Advanced Analysis. |
Here are important considerations about the watchlist:
- The watchlist only applies to Advanced Analysis.
- The watchlist can contain as many devices as allowed by the Advanced Analysis capacity, which is determined by your license.
- A device stays on the watchlist whether it is inactive or active. A device has to be active for the ExtraHop system to collect Advanced Analysis metrics.
For more information about Advanced Analysis, see Analysis levels.
The following table displays all of the operations you can perform on this resource:
Operation | Description |
---|---|
DELETE /watchlist/device/{id} | Remove a device from the watchlist. |

ExtraHop REST API examples
The following examples demonstrate common REST API operations.
Upgrade ExtraHop firmware through the REST API
You can automate upgrades to the firmware on your ExtraHop appliances through the ExtraHop REST API. This guide provides instructions to upgrade through the REST API Explorer, a cURL command, and a Python script.
Note: | If your appliance is connected to ExtraHop Cloud Services, you can simplify the upgrade process by viewing available firmware versions and downloading firmware directly to the system from ExtraHop Cloud Services. For more information, see Upgrade ExtraHop firmware through the REST API with ExtraHop Cloud Services. |
While the firmware upgrade process is similar across all ExtraHop appliances, some appliances have additional considerations or steps that you must address before you install the firmware in your environment. If you need assistance with your upgrade, contact ExtraHop Support.
All appliances must meet the following requirements:
- The firmware version must be compatible with your appliance model.
- The firmware version on your appliance must be supported by the upgrade version.
- Command appliances must be running firmware that is greater than or equal to their connected appliances.
- Discover appliances must be running firmware that is greater than or equal to connected Explore and Trace appliances.
If your deployment only includes a sensor, proceed to the API Explorer, cURL or Python upgrade instructions.
If your deployment includes additional appliance types, you must address the following dependencies before proceeding with the upgrade instructions.
If your deployment includes... | Pre-upgrade tasks | Upgrade order |
---|---|---|
Command appliances | Reserve a maintenance window of an hour for Command appliances managing 50,000 devices or more. |
|
Explore appliances | See Upgrading ExtraHop recordstores. | |
Trace appliances | None |
Upgrade ExtraHop firmware with cURL
You can upgrade the firmware on an appliance through the cURL command.
Before you begin
- The cURL tool must be installed on your machine.
- The system firmware .tar file must be downloaded on your machine.
Retrieve and run the example Python script
The ExtraHop GitHub repository contains an example Python script that upgrades multiple appliances by reading URLs, API keys, and firmware file paths from a CSV file.
Important: | The example python script authenticates to the sensor or console through an API key, which is not compatible with the RevealX 360 REST API. To run this script with RevealX 360, you must modify the script to authenticate with API tokens. See the py_rx360_auth.py script in the ExtraHop GitHub repository for an example of how to authenticate with API tokens. |
Note: | The script does not automatically disable record ingest for ExtraHop recordstores. You must manually disable record ingest before running the script for an ExtraHop recordstores. |
Upgrading ExtraHop recordstores
Pre-upgrade tasks
Before upgrading an ExtraHop recordstore, you must halt record ingest. You can halt record ingest for all of the nodes in a cluster from a single node.
Note: | The message Could not determine ingest status on some nodes and Error might appear on the Cluster Data Management page in the Administration settings of the upgraded nodes until all nodes in the cluster are upgraded. These errors are expected and can be ignored. |
- Open a terminal application.
- Run the following command, where YOUR_KEY is the API for your
user account, and HOSTNAME is the hostname of your ExtraHop
recordstore:
curl -X PATCH "https://HOST/api/v1/extrahop/cluster" -H "accept: application/json" -H "Authorization: ExtraHop apikey=YOUR_KEY" -H "Content-Type: application/json" -d "{ \"ingest_enabled\": false}"
Post-upgrade tasks
After you have upgraded all of the nodes in the recordstore cluster, enable record ingest.
- Open a terminal application.
- Run the following command, where YOUR_KEY is the API for your
user account, and HOSTNAME is the hostname of your ExtraHop
recordstore:
curl -X PATCH "https://HOST/api/v1/extrahop/cluster" -H "accept: application/json" -H "Authorization: ExtraHop apikey=YOUR_KEY" -H "Content-Type: application/json" -d "{ \"ingest_enabled\": true}"
Change a dashboard owner through the REST API
Dashboards are owned by the logged in user that created them. If a user is no longer with your company, you might need to change the owner of the dashboard to maintain that dashboard.
To transfer ownership of a dashboard, you need the dashboard ID and the username of the dashboard owner. You can only view the username of the owner of a dashboard through the REST API.
Before you begin
- For sensors and ECA VMs, you must have a valid API key with system and access administration privileges or higher. (See Generate an API key.)
- For RevealX 360, you must have valid REST API credentials with system and access administration privileges or higher. (See Create REST API credentials.)
- Familiarize yourself with the ExtraHop REST API Guide to learn how to navigate the ExtraHop REST API Explorer.
Change the dashboard owner
Tip: | After you click Send Request, the REST API Explorer provides scripts for the operation in Curl, Python 2.7, or Ruby. |
Python script example
The ExtraHop GitHub repository contains an example Python script that searches for all dashboards owned by a user account on a sensor or console and then changes the owner for all of those dashboards to another user account.
Important: | The example python script authenticates to the sensor or console through an API key, which is not compatible with the RevealX 360 REST API. To run this script with RevealX 360, you must modify the script to authenticate with API tokens. See the py_rx360_auth.py script in the ExtraHop GitHub repository for an example of how to authenticate with API tokens. |
Extract the device list through the REST API
The ExtraHop REST API enables you to extract the list of devices discovered by the sensor or console. By extracting the list with a REST API script, you can export the list in a format that can be read by third-party applications, such as a configuration management database (CMDB). In this topic, we show methods for extracting a list through both the cURL command and a Python script.
Before you begin
- For sensors and ECA VMs, you must have a valid API key to make changes through the REST API and complete the procedures below. (See Generate an API key.)
- For RevealX 360, you must have valid REST API credentials to make changes through the REST API and complete the procedures below. (See Create REST API credentials.)
Retrieve the device list with the cURL command
The device list includes all device metadata, such as MAC addresses and device IDs. However, you can filter the list of devices with a JSON parser to extract the specific information you want to export. In this example, the device list is retrieved and then filtered with the jq parser to only extract the display name of each device.
Note: | The following procedure is not compatible with the RevealX 360 REST API. To retrieve the device list from RevealX 360, see Retrieve the device list from RevealX 360 with the cURL command. |
Before you begin
- The cURL tool must be installed on your machine.
- The jq parser must be installed on your machine. For more information, see https://stedolan.github.io/jq/.
curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": MAX_DEVICES}" | jq -r '.[] | .display_name'
Note: | If the command returns no results, make sure that a trusted certificate has been added to your ExtraHop system. Alternatively, you can add the --insecure option to retrieve the device list from an ExtraHop system without a trusted certificate; however, this method is not secure and not recommended. |
Tip: | You can append the select(.analysis ==
"LEVEL") option to filter results by analysis level. For
example, the following command limits the results to include only devices
that are selected for advanced
analysis:curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": 1000000000}" | jq -r '.[] | select(.analysis == "advanced") | .display_name' |
Tip: | You can append the select(.critical ==
BOOLEAN) option to filter results by the critical field. For
example, the following command limits the results to include only devices
that are identified as critical by the ExtraHop
system:curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": 1000000000}" | jq -r '.[] | select(.critical == true) | .display_name' |
Tip: | You can append the select(.cloud_instance_name !=
null) option to filter results by the cloud instance name
field. For example, the following command limits the results to include only
devices with a cloud instance
name:curl -s -X POST "https://HOSTNAME/api/v1/devices/search" --header "accept: application/json" --header "Authorization: ExtraHop apikey=YOUR_KEY" --header "Content-Type: application/json" -d "{ \"active_from\": 1, \"active_until\": 0, \"limit\": 1000000000}" | jq -r '.[] | select(.cloud_instance_name != null) | .cloud_instance_name' |
Retrieve the device list from RevealX 360 with the cURL command
The device list includes all device metadata, such as MAC addresses and device IDs. However, you can filter the list of devices with a JSON parser to extract the specific information you want to export. In this example, the device list is retrieved and then filtered with the jq parser to only extract the display name of each device.
Note: | The following procedure is only compatible with the RevealX 360 REST API. To retrieve the device list from sensors and ECA VMs, see Retrieve the device list with the cURL command. |
Before you begin
- The cURL tool must be installed on your machine.
- The jq parser must be installed on your machine. For more information, see https://stedolan.github.io/jq/.
Create a trusted SSL certificate through the REST API
By default, sensors and consoles include a self-signed SSL certificate. However, you can improve the security and performance of your system by adding a trusted certificate signed by a certificate authority (CA). You can create the certificate signing request to send to your CA through the ExtraHop REST API. After you receive the signed certificate, you can also add it to your sensor or console through the REST API.
Before you begin
- You must log in to the sensor or console with an account that has system and access administration privileges to generate an API key.
- You must have a valid API key to make changes through the REST API and complete the procedures below. (See Generate an API key.)
- Familiarize yourself with the ExtraHop REST API Guide to learn how to navigate the ExtraHop REST API Explorer.
Note: | You can also perform the procedures in this topic through the Administration settings. For more information, see the following topics: |
Create an SSL certificate signing request
To create a signed SSL certificate, you must send a certificate signing request to a trusted CA.
Next steps
Send the signing request to your CA to create your signed SSL certificate.Important: | The signing request contains escape sequences that represent line
breaks (\n). Replace each instance of \n with a line break before sending the
request to your CA. You can modify the PEM request manually in a text editor or
automatically through a JSON parsing utility, as shown in the following example
command:echo '<json_output>' | python -c 'import sys, json; print json.load(sys.stdin)["pem"]' Replace the <json_output> variable with the entire JSON string returned in the Response Body section. |
Create custom devices through the REST API
You can create custom devices through the REST API that track network traffic across multiple IP addresses and ports. For example, you might want to add a custom device for each branch office. If you create the devices through a script, you can read the list of devices from a CSV file. In this topic, we will demonstrate methods for both the REST API and the ExtraHop REST API Explorer.
Before you begin
- You must log in to the sensor with an account that has system and access administration privileges to generate an API key.
- You must have a valid API key to make changes through the REST API and complete the procedures below. (See Generate an API key.)
- Familiarize yourself with the ExtraHop REST API Guide to learn how to navigate the ExtraHop REST API Explorer.
Create and assign a device tag through the REST API
The following Python script creates a device tag and then assigns that tag to all of the devices in a specified subnet.
#!/usr/bin/env python import httplib import urllib import json import sys # Configuration Options: host = "{HOST}" apikey = "{API KEY}" tag_name = "MyTestTag" subnet = "10.20.0.[0-9]+" batch_limit = 100 headers = {'Accept': 'application/json', 'Authorization': "ExtraHop apikey=%s" % apikey} conn = httplib.HTTPSConnection(host) def execute_req(method, path, expected_code, failure_message, body=None): """ Returns the body of a successful request, otherwise prints error and terminates """ conn.request(method, "/api/v1" + path, headers=headers, body=body) resp = conn.getresponse() if resp.status is not expected_code: print(failure_message) print(resp.read()) sys.exit(1) return resp def execute_get(path, expected_code, failure_message): resp = execute_req("GET", path, expected_code, failure_message) return json.loads(resp.read()) def execute_create(path, body, expected_code, failure_message): """Returns ID of newly created resource""" resp = execute_req("POST", path, expected_code, failure_message, body) resp.read() # drain the response return int(resp.getheader("location").split("/")[-1]) # First, search for the specified tag, by name resp = execute_get("/tags", 200, "Unable to retrieve tags from ExtraHop") tags = [tag for tag in resp if tag["name"] == tag_name] if not tags: # tag is not found, create it body = json.dumps({"name": tag_name}) tag_id = execute_create('/tags', body, 201, "Unable to create tag") else: tag_id = tags[0]["id"] query_params = {'limit': batch_limit, 'search_type': 'ip address', 'value': subnet} query_string = urllib.urlencode(query_params) # Paginate device results, building up a list of all devices to assign device_ids = [] offset = 0 while True: path = "/devices?" + query_string + ("&offset=%d" % offset) resp = execute_get(path, 200, "Unable to retrieve devices") if not resp: break device_ids += [device["id"] for device in resp] offset += batch_limit # Perform the assignments resp = execute_req("POST", "/tags/%d/devices" % tag_id, 204, "Unable to perform assignments", body=json.dumps({"assign": device_ids})) resp.read() # drain the response # Check that assignments were successful resp = execute_get("/tags/%d/devices" % tag_id, 200, "Unable to retrieve tag assignments") assigned_device_ids = [device["id"] for device in resp] successful = set(device_ids).issubset(set(assigned_device_ids)) if successful: print("%d devices assigned to tag" % len(device_ids)) else: print("Unable to assign all devices to tag")
Query for metrics about a specific device through the REST API
The following Python script queries for metrics from an HTTP client device with the ID 9363 and prints the response.
import httplib headers = {'Content-Type': 'application/json', 'Accept': 'application/json', 'Authorization': 'ExtraHop apikey={API KEY}' body = r"""{ "cycle": "auto", "from": -1800000, "until": 0, "metric_category": "http_client", "metric_specs": [ { "name": "req" } ], "object_ids": [ 9363 ], "object_type": "device" }""" conn = httplib.HTTPSConnection('{HOST}') conn.request('POST', '/api/v1/metrics', headers=headers, body=body) resp = conn.getresponse() print resp.status, resp.reason print resp.read()
The following response shows entries for the device with ID 9363:
{ "date": "Thu, 19 Nov 2015 23:20:07 GMT", "via": "1.1 localhost", "server": "Apache", "vary": "Accept-Encoding", "content-type": "application/json; charset=utf-8", "cache-control": "private, max-age=0", "connection": "Keep-Alive", "content-encoding": "gzip", "keep-alive": "timeout=45, max=44", "content-length": "277" } { "stats": [ { "oid": 9363, "time": 1447973460000, "duration": 30000, "values": [ 2 ] }, { "oid": 9363, "time": 1447973490000, "duration": 30000, "values": [ 0 ] }, { "oid": 9363, "time": 1447973520000, "duration": 30000, "values": [ 1 ] }, { "oid": 9363, "time": 1447973550000, "duration": 30000, "values": [ 2 ] }
Create, retrieve, and delete an object through the REST API
This example shows how you can create and successfully retrieve information about a device tag. Then, after the device tags are deleted, the example shows how an attempt to retrieve information subsequently fails.
The following example shows how to create a device tag called my_test_tag.
curl -i -X POST --header "Content-Type: application/json" \ --header "Accept: application/json" \ --header "Authorization: ExtraHop apikey={API KEY}" \ -d "{ \"name\": \"my_test_tag\" }" "https://{HOST}/api/v1/tags"
A 201 status returns upon success with the following response headers, which display that the tag was created, and provides the device tag location and ID of /api/v1/tags/1.
{ "date": "Wed, 18 Nov 2015 20:24:13 GMT", "via": "1.1 localhost", "server": "Apache", "content-type": "text/plain; charset=utf-8", "location": "/api/v1/tags/1", "cache-control": "private, max-age=0", "connection": "Keep-Alive", "keep-alive": "timeout=45, max=88", "content-length": "0" }
Next, the ID (1) is added to the following GET request, which returns a 200 status upon success and the JSON representation of the retrieved tag:
curl -i -X GET --header "Accept: application/json" \ --header "Authorization: ExtraHop apikey={API KEY}" \ "https://{HOST}/api/v1/tags/1" { "mod_time": 1447878253953, "id": 1, "name": "my_test_tag" }
Next, the following example shows a DELETE request to remove the device tag from the system, which returns a 204 status upon success:
curl -i -X DELETE --header "Accept: application/json" \ --header "Authorization: ExtraHop apikey={API KEY}" \ "https://{HOST}/api/v1/tags/1"
Finally, when another GET request is sent for that deleted device tag, the operation fails, and a 404 status is returned upon failure, indicating that the tag is no longer available.
curl -i -X GET --header "Accept: application/json" \ --header "Authorization: ExtraHop apikey={API KEY}" \ "https://{HOST}/api/v1/tags/1"
Query the record log
The following request body queries the record log to retrieve 100 HTTP records where the method is GET and the status code is 404.
{ "filter": { "operator": "and", "rules": [ { "field": "method", "operand": "GET", "operator": "=" }, { "field": "statusCode", "operand": "404", "operator": "=" } ] }, "from": -900000, "limit": 100, "types": [ "~http" ] }
