# webhook.test

Zernio sent a test event to an endpoint.

### When it fires

Sent when you call Test webhook or press test in the dashboard, whatever events the endpoint subscribes to. Sent once, synchronously, and never retried.




**Payload for `webhook.test`:**

- **id** (required) `string`: Stable webhook event ID: the dedupe key, also sent as the X-Zernio-Event-Id header and identical on every retry and redelivery. It identifies the event only, never an account or other resource.
- **event** (required) `string`: No description - one of: webhook.test
- **message** (required) `string`: Human-readable test message
- **timestamp** (required) `string` (date-time): UTC time at which Zernio generated this test event (set once when the payload is built). Test fires are sent synchronously as a single attempt; a later redelivery of this event keeps the original value.
