Publishes the draft as a new version and makes it live, or resumes a paused automation.

People already in the flow stay on the version they started on. The caller needs the permissions of the flow's steps, such as sending notifications.

Guide: Automations

Errors

It can also fail with the errors every operation shares, such as unauthenticated; see Errors.
