Setup Instructions​

Google Play Store integration requires data from your application in the Google Play Console. For this, a project on Google Cloud is necessary so that IAPGUARD can authenticate and access your Google Play application backend via the Google Play Android Developer API. Due to the nature of this integration requiring multiple Google backends, there will be a bit of jumping back and forth between them.

note

Note that the initial setup and configuration of your project in Google Cloud can take up to 36 hours for it to successfully establish a connection to the Google Play API. During this time, testing receipt validation with IAPGUARD will fail, even when sending valid receipts.

In the following screenshot, you can see the required fields we are going to fill out. Edit your Application to get started.

Please contact Support if you have issues with this process or require further assistance.

The Bundle ID is displayed when editing your application in Google Play Console.

1. Open the Google Play Console

2. Navigate to Your App > Dashboard

3. Copy-paste the identifier below your app name into the IAPGUARD Dashboard as Bundle ID

Account ID​

10. Scroll down to Permissions and grant account-wide permissions to:

  • View app information and download bulk reports (read only)
  • View financial data, orders and cancellation survey responses
  • Manage orders and subscriptions

Instead of account-wide permissions, you can also grant permissions for individual apps only, if you wish to.

tip

If you do not want to wait 36 hours for Google to take over your changes and service account permissions, you can head to your app's In-App Products or Subscriptions section in the Google Play Developer Console and quickly Disable & Re-Activate a product to force an update by Google. This is not an official workaround but was confirmed to work for many other developers.

License Key​

Please note that the following key file can only be downloaded once, so make sure to save it in a secure location.

1. In Google Cloud, navigate to Service Accounts (IAM & Admin > Service Accounts)

2. Select Actions > Manage Keys

3. Add a new JSON key

GooglePlay-Setup060

GooglePlay-Setup065

4. Open the downloaded JSON file

5. Copy-paste the value for private_key into the IAPGUARD Dashboard as License Key (without quotation marks)

GooglePlay-Setup070

Again, note that the full key should be copied, including the -----BEGIN PRIVATE KEY... -----END PRIVATE KEY-----\n parts.

Server Notifications​

caution

This step is required when offering subscriptions. Real-time developer notifications (RTDN) enable IAPGUARD to receive information about subscription states and expirations in realtime for updating user inventory.

note

Google Real-time developer notifications (RTDN) using the Pub/Sub service are not completely free, however there is a free contingent of 10 TiB per month. This should be sufficient to process millions of messages every month. It is unlikely that your applications receives that many messages, except if you have hundreds of thousands of in-app purchases as well.

1. Navigate to Cloud Pub/Sub API and enable it

GooglePlay-Setup300

2. Navigate to Pub/Sub (Solutions > All Products > Analytics > Pub/Sub)

3. Create a new Topic with a default subscription
