Process Search V2 API for Enterprise EDR

Carbon Black Cloud Enterprise EDR (Endpoint Detection and Response) is the new name for the product formerly called CB ThreatHunter.

Version: v2

Service Category has changed.

You may continue to access the API from /threathunter/search/ until December 31st, 2020. For more information see here.

This API is moving locations.

You may continue to access the documentation here. To see the latest documentation for these APIs see here for Enriched Events and here for Processes.

Getting Started

Enterprise EDR’s process searches are asynchronous. This means that in order to get results for a search query, you must start a search by calling POST /search_jobs and then get results by calling GET /results on the /search_jobs/ route with query_id as a URL parameter. New to the v2 Search API is a separate set of requests for facets to quickly obtain prevalence of many filtering terms - similarly calling POST /facet_jobs followed by GET /results on the /facet_jobs/ route with the respective query_id.

For more information about Process and Event Search Fields.

Common Headers

Most API routes require all three headers, however, there are exceptions.

  1. X-Auth-Token: required. This is your authentication token, it is api_key/connector_id.
  2. Content-Type: application/json
  3. accept: application/json

Note

  • <cbc-hostname> is the parent URL for your Carbon Black Cloud instance.
  • {org_key} or org_key refers to your organization key found in the Carbon Black Cloud’s APIs page.
