Inspect Webhook Delivery and Replay

What You Can Inspect

Endpoint Configuration

Review endpoint label, host, active/paused state, event filters, allowed host, signing algorithm, and max attempts.

Inspect recent deliveries by event, endpoint, status, attempt count, last attempt time, and response status.

Confirm whether a delivery was signed. The dashboard stores a signature hash for evidence, not the raw secret.

Queue replay for failed or dead-lettered deliveries after you fix your endpoint.

Delivery Headers

Webhook deliveries include these headers:

Header	Meaning
`X-HomeServiceData-Event`	Event type, such as `dataset.version.published`
`X-HomeServiceData-Delivery`	Delivery identifier for idempotency and support
`X-HomeServiceData-Signature`	HMAC-SHA256 signature in `sha256=<hex>` format
`X-HomeServiceData-Timestamp`	Unix timestamp used in the signature base string
`Idempotency-Key`	Stable event-endpoint key for duplicate protection

The signature base string is:

<timestamp>.<raw request body>

Replay Workflow

Open Webhooks

Find the failed delivery

Filter visually by status. Failed and dead-lettered deliveries show response status, response preview, or error message when available.

Fix your endpoint

Correct authentication, URL allowlist, timeout, or handler errors before replaying.

Queue replay

Use Queue replay on the failed delivery. The delivery returns to the dispatch queue and is attempted again by the dispatcher.
