Delivery & retries
Your endpoint should respond with a 2xx status within 8 seconds. Anything else is treated as a failure and queued for retry.
Retries: up to 3 attempts after the initial delivery
Backoff: 1 min, 5 min, 30 min, 2 hr, 8 hr (exponential, jittered)
Window: retries stop after 24 hours; the event is then marked failed
Replay: any failed delivery can be manually replayed from the activity log for up to 30 days
Order: events are not ordered. Use occurredAt to sort if you need a sequence
