Validate receipt in android

For Android, you need separate json file from the service account to get the access_token from google-apis, therefore it is impossible to implement serverless. You should have your own backend and get access_token.

Example:

const result = await validateReceiptAndroid(
  packageName: 'com.dooboolab.iap',
  productId: 'product_1',
  productToken: 'some_token_string',
  accessToken: 'play_console_access_token',
  isSubscription: false,
);
console.log(result);

Implementation

Future<http.Response> validateReceiptAndroid({
  required String packageName,
  required String productId,
  required String productToken,
  required String accessToken,
  bool isSubscription = false,
}) async {
  final String type = isSubscription ? 'subscriptions' : 'products';
  final String url =
      'https://www.googleapis.com/androidpublisher/v3/applications/$packageName/purchases/$type/$productId/tokens/$productToken?access_token=$accessToken';
  return await _client.get(
    Uri.parse(url),
    headers: {
      'Accept': 'application/json',
    },
  );
}
