# pushToStartToken

The token you use to start a Live Activity with an ActivityKit push
notification.

```
static var pushToStartToken: Data? { get }
```

## Discussion

The push token for a Live Activity may change over time. Use the [`pushToStartTokenUpdates`](/documentation/ActivityKit/Activity/pushToStartTokenUpdates)
asynchronous sequence to receive an updated push-to-start token. When
you receive an updated push token, make sure to send it to your server
and invalidate the outdated token.
