WHAT IT DOES

What pause_campaign does on Flour Ads

AI agents use pause_campaign to create or update resources in Flour Ads — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Flour Ads environment.

WHY IT NEEDS A POLICY

Why pause_campaign needs a policy

Pausing a campaign is a reversible state change (it can be resumed via resume_campaign), making it Write rather than Destructive. However, the blast radius is high because pausing an active ad campaign immediately stops all ad delivery, which can cause significant business impact — lost impressions, leads, and revenue — if done incorrectly or maliciously.

Verdict

pause_campaign Rate-limited

pause_campaign stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
