```
timestamp signedDate
```

## Discussion

This timestamp indicates the time the system signs the data before it sends the notification to your server. The notification payload contains a snapshot of the state of the transaction at this time.

This timestamp remains the same if the system resends the notification during a retry. For more information about retries, see [Responding to App Store Server Notifications](/documentation/AppStoreServerNotifications/responding-to-app-store-server-notifications).

If you process multiple notifications for the same transaction ID, use the notification with the most recent `signedDate`, because it contains the most recent snapshot of the transaction’s status.
