Webhooks

Webhooks connect Frontal to event-driven systems. An inbound event can trigger a workflow; an outbound event can notify another system about a completed run, an approval, or a failed action.

Verify incoming requests before accepting them, record the external event ID, and make the target workflow idempotent. For delivery, return a fast success response, process the event asynchronously, and use the run ID as the correlation handle for support and retries.

Do not use a webhook as an unbounded public write endpoint. Keep payload validation, workspace routing, and policy checks explicit.
