In order for RevenueCat's servers to communicate with Google on your behalf you need to provide a set of service credentials. The process for configuring these credentials is a bit complex, but the added level of control improves security by only providing RevenueCat with the access we need.
1. Link to a Google Developer Project
Your Play Developer account needs to be linked to a Google Developer Project.
1a. Open the Settings > Developer account menus and select API access


1b. Select Link to connect your Play account to a Google Developer Project


1c. Agree to the terms and conditions


2. Create Service Account
Next we need to create a service account. This is done from the Google API Console.
2a. Select Create Service Account


2b. Follow the link to the Google API Console


2c. Create Service account key credentials


2d. Name it and assign it Pub/Sub Admin Role
When you hit create, a JSON file will be downloaded. These are the credentials that RevenueCat will need to communicate with Google.


Set the Role to Pub/Sub Admin (to enable Platform Server Notifications)


You can skip the optional third step, "Grant users access to this service account" by clicking Done.


In the Google Cloud Console, click on Actions > Create key to create your JSON key.


Create and your JSON credential:




The downloaded JSON key is what you will need to enter in RevenueCat in step 4.
3. Grant Financial Access to RevenueCat
3a. Back in the Play Console, select Grant Access on the newly created RevenueCat service account


3b. Grant the following permissions:
- View app information and download bulk reports (read-only)
- View financial data, orders, and cancellation survey responses
- Manage orders and subscriptions


3c.Click Invite User at the bottom and send the invite


You will be redirected to Users and Permissions where you should see your newly created service account as Active.
3d. Apply permissions to your apps
In the Users and Permissions section, click on the service account and add your apps to the account. Click Apply on the sheet that appears.




4. Enter the credentials JSON in RevenueCat
Copy and paste the credentials JSON that were downloaded in step 2 to your RevenueCat account and we'll be ready to handle Google Play purchases!


Important
It can take up to 36 hours for your Play Service Credentials to work properly with the Android Developer API. You may see "Invalid Play Store credentials" errors and be unable to make purchases with RevenueCat until this happens.
