Google Play Store Notifications 

After successful Chargebee API integration, new subscriptions will be synced to Chargebee from Google Play Store. To maintain any changes to the status of a subscription, it is important to set up Chargebee to receive notifications from Google. We will now guide you through the process of configuring Chargebee to receive notifications from Google publishing APIs.

The status of a subscription may change based on customer actions and the change must be effectively captured on your Chargebee site too. This can be accomplished by enabling real-time notifications via Google Real-Time Developer Notifications (RTDN)  to Chargebee.

You must configure a Topic id for Chargebee to receive notifications from Google publishing APIs. Click here  for more information about Topics.

This can be achieved using one of the following options:

• Allow Chargebee to generate a Topic ID to receive notifications.
• Configure an existing Pub/Sub Topic.

Generation of a Topic ID

• If the subscription to the topic is successful, Chargebee is set to receive notifications.
• If the subscription to the topic is unsuccessful, rectify the errors or contact support  for additional assistance.

Update Topic ID 

You can choose to update your subscription to the Topic ID at any time. This can be accomplished with the same steps as the first time setup. You need to choose between generating or using an existing topic with appropriate Pub/Sub admin roles assigned.

Error Management 

You may encounter various errors while configuring notifications associated with Topic ID. Review the error messages and resolutions listed below:

Service Account Permissions 

If you receive an error during the generation or configuration of an existing Topic ID, it is most likely due to inadequate permissions in the Service Accounts. Ensure that the service account has pub/sub admin & monitoring viewer permissions. Click here for assistance with configuring appropriate permissions to your Service Account on the Google Cloud Platform.

Validation Errors 

Any validation errors while configuring an existing Topic ID is most likely due to a mismatch between the existing topic id configured in Chargebee and Google Cloud platform.

General Errors 

If you encounter errors while creating or subscribing to a Topic ID not listed above, we recommend you retry the notification setup again. If the issue persists please contact [[link_static https://chargebee.freshdesk.com/support/home]support[].

App ID 

The App ID is a unique identifier created for your Play Store application within Chargebee. This identifier is configured in the backend server of your app to create unique API endpoints which can be used extensively for completing API actions and to configure the SDK. Follow the steps below to retrieve this information:

1. Click Set up Notifications from the Sync Overview page.

   

2. Click Copy to add the App ID to your clipboard.
