When webhooks flow through the Hookdeck Event Gateway, Hookdeck queues and delivers them to your app. Each forwarded request is signed with an x-hookdeck-signature header (HMAC SHA-256, base64). Your handler verifies this signature to confirm the request came from Hookdeck.

When Hookdeck forwards a request to your destination, it adds these headers:
| Header | Description |
|---|---|
x-hookdeck-signature | HMAC SHA-256 signature (base64) — verify this |
x-hookdeck-eventid | Unique event ID (use for idempotency) |
x-hookdeck-requestid | Original request ID |
x-hookdeck-source-name | Source that received the webhook |
x-hookdeck-destination-name | Destination receiving the webhook |
x-hookdeck-attempt-count | Delivery attempt number |
x-hookdeck-attempt-trigger | What triggered this attempt: INITIAL, AUTOMATIC, MANUAL, BULK_RETRY, UNPAUSE |
x-hookdeck-will-retry-after | Seconds until next automatic retry (absent on last retry) |
x-hookdeck-event-url | URL to view event in Hookdeck dashboard |
x-hookdeck-verified | Whether Hookdeck verified the original provider's signature |
x-hookdeck-original-ip | IP of the original webhook sender |
Hookdeck also preserves all original headers from the provider (e.g., stripe-signature, x-hub-signature-256).
