Google Play Store Integration

Your backend receives the Google Play purchase token from the app and forwards it to Frisbii Media for validation. Frisbii Media validates it server-to-server with Google and returns an inAppToken.

Add a Google Play purchase

/**
 * @Route("/google/purchases/add", name="GooglePurchase", methods={"POST"})
 */
public function addGooglePurchase(Request $request): Response
{
    $content       = json_decode($request->getContent(), true);
    // The app package name sent by the app as a request header
    $appIdentifier = $request->headers->get('x-app-bundle');
    // @see https://api.frisbii-media.com/#tag/App-Stores/operation/addGooglePlaystorePurchase
    $response = json_decode($client->request('POST', '/appstores/google/purchases', [
        'headers' => ['X-plenigo-token' => eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9],
        'json'    => [
            'appIdentifier' => $appIdentifier,
            'purchaseToken' => $content['purchaseToken'], // purchase token from Google Play Billing
            'productId'     => $content['productId'],     // Google Play product/SKU ID
        ],
    ])->getBody()->getContents(), true);
    // inAppToken identifies this purchase until it is associated with a customer
    $inAppToken = $response['inAppToken'];
    return new JsonResponse(['inAppToken' => $inAppToken]);
}

Verify an existing Google Play purchase

Google sends Real-time Developer Notifications (RTDN) via Pub/Sub to your backend for subscription events — renewals, cancellations, refunds, and so on. Forward each notification to Frisbii Media using the verify endpoint to keep the subscription state in sync.

/**
 * @Route("/google/purchases/verify", name="GooglePurchaseVerify", methods={"POST"})
 */
public function verifyGooglePurchase(Request $request): Response
{
    $content       = json_decode($request->getContent(), true);
    $appIdentifier = $request->headers->get('x-app-bundle');
    // @see https://api.frisbii-media.com/#tag/App-Stores/operation/verifyGooglePlaystorePurchase
    $response = json_decode($client->request('PUT', '/appstores/google/purchases/verify', [
        'headers' => ['X-plenigo-token' => eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9],
        'json'    => [
            'appIdentifier' => $appIdentifier,
            'purchaseToken' => $content['purchaseToken'],
            'productId'     => $content['productId'],
        ],
    ])->getBody()->getContents(), true);
    return new JsonResponse($response);
}

Tip: The verify endpoint is idempotent — passing the same purchase token more than once does not create a duplicate order.

Request payload reference

Configuring Google Real-time Developer Notifications

To receive ongoing subscription lifecycle events from Google, you must configure RTDN in the Google Play Console:

1. Go to Google Play Console → Your app → Monetisation setup → Real-time developer notifications

2. Set the Pub/Sub topic to your backend's verify endpoint URL

3. Google will send a Pub/Sub message for every subscription event; decode the data field (base64) to get the notification payload

Pass the purchaseToken and productId from the decoded notification to the verify endpoint.
