Airship is a leading Push Communication API provider that enables developers to send notifications to users' devices. It is widely used in mobile applications to enhance user engagement by delivering timely and relevant messages. Airship supports various platforms, including iOS, Android, and web, making it a versatile tool for developers.
When using Airship, you may encounter the error message 'Device Token Not Found.' This issue typically arises when attempting to send a push notification to a device. The symptom is clear: the notification fails to deliver, and the error message indicates that the device token is not recognized.
The 'Device Token Not Found' error occurs when the device token you are using is either incorrect or not registered with Airship. Device tokens are unique identifiers for devices, and they must be accurately registered with Airship to receive notifications. This error can disrupt the notification delivery process, affecting user engagement.
To resolve this issue, follow these detailed steps:
Ensure that the device is properly registered with Airship. You can do this by checking your registration logic in the application code. Make sure that the device token is being sent to Airship during the registration process.
Double-check the device token for any errors. Ensure that it is correctly copied and formatted. Device tokens are case-sensitive and must match exactly.
If the device token is still not found, try re-registering the device. This can be done by removing the app from the device and reinstalling it, which will trigger a new registration process.
Utilize Airship's API to validate the device token. You can use the Get Channel ID endpoint to check if the token is registered. This can help confirm whether the token is valid and recognized by Airship.
By following these steps, you should be able to resolve the 'Device Token Not Found' issue in Airship. Ensuring accurate device registration and token management is crucial for the successful delivery of push notifications. For more detailed guidance, refer to the Airship Documentation.
