Replay a delivery
Schedule a fresh attempt for the given (message, endpoint). Idempotent via the stable webhook-id. Messages older than the replay ceiling (default 30 days) are refused with 409 webhook_replay_too_old; the envelope’s timestamp carries the original occurrence time.
Authentication: Supports API key and bearer token authentication.
Authentication
Bearer authentication of the form Bearer <token>, where token is your auth token.
Path parameters
Headers
A unique key (up to 255 printable ASCII characters, e.g. a UUID) that makes a retry of this request safe. Envoy stores the response for 24 hours; a retry with the same key and the same request returns it again with Idempotent-Replayed: true instead of running twice. The same key with a different request returns 422 idempotency_key_reused; while the first request is still running, 409 idempotency_key_in_progress. 5xx and 429 responses are not stored.
Request
Response
Per-attempt delivery state.
SENDING is the transient state that prevents double-sends: the
delivery task atomically flips PENDING → SENDING (compare-and-set
on the row) before doing the outbound POST, so any other worker that
picks up the same row from the sweeper backs off cleanly. Always a
terminal status (SUCCEEDED/FAILED/DEAD) by the time the task returns.
The envelope as delivered (id, type, timestamp, data).
