Source API

The threat intelligence Source API updates and returns information about tasks related to threat intelligence source configurations.

Create or update a threat intelligence source

Creates or updates a threat intelligence source and loads indicators of compromise (IOCs) from that source.

Path and HTTP methods

POST _plugins/_security_analytics/threat_intel/sources
PUT _plugins/_security_analytics/threat_intel/sources/<source_id>
