Receive real-time events
Configure your webhook endpoints in Settings -> Webhooks in the dashboard. Accend signs every delivery with HMAC-SHA256. Verify the signature before you process the event. Respond with200 immediately and move the real work to an async job.
If your endpoint does not return
2xx within 30 seconds, Accend retries with exponential backoff: 10s -> 30s -> 2m -> 10m -> 1h -> 6h -> 24h.
