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 with 200 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.
