# 60706: Invalid Push Token

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when you register an iOS device for push notifications and the `PushToken` value is empty or not a valid APNs device token. When you create an `apn` Binding, use the device token returned by iOS as the Binding `Address`.

### Possible causes

* The app sent an empty `PushToken` value when it tried to register the device.
* The app converted the APNs device token incorrectly. On iOS 13 and later, parsing `[deviceToken description]` can produce an invalid token string. Build the token as a hexadecimal string from the raw bytes instead.
* The app tried to create the Binding before iOS finished registering for remote notifications and returned a device token.
* The app's push configuration does not match the app build that generated the token, such as a bundle identifier mismatch.

### Possible solutions

* Wait until iOS successfully registers for remote notifications, then submit the returned device token when you register the device.
* For `apn` Bindings, send the APNs device token as the Binding `Address`. Do not send an empty string, placeholder value, or a token from another push provider.
* Convert the iOS `deviceToken` from bytes to a hexadecimal string. Do not rely on `[deviceToken description]` on iOS 13 and later.
* Confirm that your Apple push setup uses an explicit bundle identifier that matches the bundle identifier in Xcode, then register the device again with a fresh token from that app.
