AI agents use phishfort_rotate_webhook_secret to create or update resources in Phishfort — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Phishfort environment.
Rotating a webhook secret modifies the credential used to authenticate webhook deliveries. This is a Write action (it changes/regenerates a secret), but it carries high severity because it invalidates the previous secret, potentially breaking existing webhook integrations. It is not Destructive because the webhook itself is not deleted and the action can be remediated by rotating again.
From the tool's definition 'Rotate webhook secret. One-time secret is saved locally, not returned.'
