Configure in-app purchase (Android)

How to connect in-app purchases with Google Play Console

If your app unlocks digital content such as premium features, subscriptions, Google recommends using In-app purchases.

Before starting, ensure you have already created the in-app purchase product in your AppMySite dashboard. You will need the generated Product ID during this setup.

Step 1: Set up a Payments profile

• Log in to Google Play Console.

• From the left side menu, go to Settings.

• Click Create payments profile.

• Complete the required payment details.

In-app purchases cannot be enabled without an active Payments profile in Google Play Console.

Step 2: Enable real-time developer notifications

• In Google Play Console, select your app.

• From the left menu, go to Monetisation with Play > Monetisation setup.

• Under Google Play Billing, enable Real-time developer notifications.

• Add a topic name. The topic name is the Project ID that you can find in your Firebase account

• To find your Project ID: go to Firebase > Settings > General.

• Copy the Project ID.

Enter the topic in this format: projects/PROJECT-ID/topics/play-notifications

• Under Notification content, select Subscriptions, voided purchases, and all one-time products.

• Click Save changes.

The Project ID is unique for all accounts and must match the Firebase project connected to your Android app.

Step 4: Configure Pub/Sub in Google Cloud Console

• Log in to Google Cloud Console.

• Select the project linked to your Android app.

• Search for Pub/Sub and open it.

• Click Create topic and enter a topic name.

• Open the created topic and click the subscription ID.

• Click Edit.

• Set Delivery type to Push.

• Copy the Endpoint URL from your AppMySite In-app purchase dashboard and paste it into the Endpoint URL field. You can find the Endpoint URL in the Server URL field in your AppMySite In-app purchase dashboard

• In Subscription permissions, click Add principal.

• Add: [email protected]

• Assign the role Pub/Sub Publisher.

• Click Update to save changes.

Ensure the Endpoint URL is copied exactly from your AppMySite dashboard to allow proper validation of in-app purchases.

Step 5: Configure in-app products

• In your Google Play Console, select your app from the app listing screen.

• From the left navigation menu, go to Monetize > Products >One-time products/Subscriptions.

• Click Create one-time product/Create Subscriptions.

• Enter the Product ID generated in your AppMySite in-app purchase dashboard.

• Fill in the remaining product details.

• Click Save.

The Product ID in Google Play Console must exactly match the Product ID created in your AppMySite dashboard.
