Step 2: Implement Server-Side Integration

  • Configure your backend server to handle Google Pay™ payment requests.

  • Set up a secure endpoint to receive encrypted payment data requests from the Google Pay™ SDK.

  • Alternatively, you can send the encrypted payment data directly from your mobile app if you do not wish to integrate it from your backend server.

  • Follow the API integration to send a request to Callphone to process the request.
