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.

Your Play Developer account needs to be linked to a Google Developer Project.

1a. Go to your Play Console settings

1b. Select API access

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

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 Project Owner 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 Project > Owner

Download your JSON credential

3a. Back in the Play Console, select Grant Access on the newly created RevenueCat service account

3b. Set the Role to Finance and Add Manage Orders Permissions

Hit save and you're done. Upload the credentials JSON that were downloaded in step 2 to your RevenueCat account and we'll be ready to handle Google Play purchases!
