Create a job triggered by a delta in a feed

Create feed-delta jobs in Cortex XSOAR 8 SaaS.

Jobs triggered by a delta in a feed (event triggered jobs) run when a feed completes an operation and there is a change in the content. For the job to trigger, there must be a delta between the incoming feed and the previous one. You can define a job to trigger a playbook when the specified feed or feeds finish a fetch operation that includes a modification to the feed. The modification can be a new indicator, a modified indicator, or a removed indicator. For example, you may want to update your firewall every time a URL is added, modified, or removed from the Office 365 feed. You can configure a job that triggers the firewall update playbook to run whenever a modification is made to the feed.

For an example of using a job triggered by a delta in a feed, see the Create jobs to process indicators example.

A job triggered by a delta in a feed runs only if there is a change in the feed, and does not run on a feed’s initial fetch. For the initial fetch, you can run the playbook manually and then set up an event triggered job for subsequent fetches.

If you want to trigger a job after a feed completes a fetch operation and the feed does not change frequently, you can select the Reset last seen option in the feed integration instance. The next time the feed fetches indicators, it will process them as new indicators in the system.
