When a webhook cannot be delivered within its 72-hour retry window — your endpoint was down the whole time — it is dead-lettered: removed from the retry queue rather than retried forever. There is no separate dead-letter feed; the recovery path is to re-read the affected resources from the API and reconcile. Keeping your endpoint healthy inside the window prevents dead-lettering entirely.
Frequently asked questions
How do I recover a dead-lettered event?
Re-fetch the resource from the read API and reconcile against your records. Your idempotent handler makes re-applying safe. See Replay and recover missed webhooks.
