See recent delivery attempts to a subscription: what was sent, when, the response your endpoint gave, and any retries. Use this to debug an endpoint that isn't receiving events, or to confirm a test worked. Returns attempts, newest first: 50 by default, up to 100 with limit. Filter by status, event and since, and pass the last entry's id as before_id to page back through older attempts. Each event is tried up to 6 times: immediately, then 1 minute, 5 minutes, 30 minutes, 2 hours and 6 hours after each failed attempt. Use status=dropped to list the events given up after their last attempt.

Prerequisites: a Partner bearer token and the subscription's id (from List your webhooks).

Authentication: Partner token. Only partner users can call it; other tokens get 403. Only your own partner's subscriptions: any other id gets 404.

Rate limit: none.
