## Register for push notifications
---
This method passes the Firebase Token to Synerise for notifications.
- You should call this method every time the user changes the system or application consent for notifications.
- The API key must have the `API_PERSONAL_DEVICE_CLIENT_UPDATE` permission from the **Client** group.
- If the registration fails, the SDK requests a token update again by a listener/delegate method ([Android](/developers/mobile-sdk/listeners-and-delegates/android-listeners#on-register-for-push-listener), [iOS](/developers/mobile-sdk/listeners-and-delegates/ios-delegates#synerise-delegate-register-for-push-notifications-is-needed), [React Native](/developers/mobile-sdk/listeners-and-delegates/react-native-listeners#notifications-listener), [Flutter](/developers/mobile-sdk/listeners-and-delegates/flutter-listeners#notifications-listener)).
```Kotlin
val call = Client.registerForPush(refreshedToken, true)
call.execute({ Log.d(TAG, "Register for Push succeed: " + refreshedToken) },
{ apiError-> Log.w(TAG, "Register for push failed: " + refreshedToken) })
```
