# testNotificationToken

A unique identifier for a notification test that the App Store server sends to your server.

```
string testNotificationToken
```

## Discussion

You receive a `testNotificationToken` when you call the [`Request a Test Notification`](/documentation/AppStoreServerAPI/Request-a-Test-Notification) endpoint. Use the `testNotificationToken` to learn your server’s response to the test by calling [`Get Test Notification Status`](/documentation/AppStoreServerAPI/Get-Test-Notification-Status).
