A ‘message’ is identified by the event id and spans all endpoints subscribed at the time the event was emitted. Returns every recorded attempt for this org’s endpoints.
Authentication: Supports API key and bearer token authentication.
Bearer authentication of the form Bearer <token>, where token is your auth token.
Stable per (event, endpoint) — same across retries.
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).
