Google Play Store
Step-by-step guide for creating your Play service credentials
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 providing RevenueCat with only the access we need.
Credentials can take up to 36 hours after being created to be valid
It can take up to 36 hours for your Play Service Credentials to work properly with the Google Play Developer API. You may see "Invalid Play Store credentials" errors (503 or 521) and be unable to make purchases with RevenueCat until this happens.]
Note that this setup takes place on both the Google Play Console and the Google Cloud Console. Due to the nature of the process, there’s some switching back and forth between each console that can’t be helped, but each step will make clear which console you should be looking at.
1. Linking to a Google Cloud Project
- Where: Google Play Console
- Developer homepage Setup section of sidebar API Access
In API Access, either link to connect an existing Google Cloud Project or create a new project. Make sure to save, and agree to any terms and conditions of service pop ups.
2. Create a Service Account
- Where: Google Cloud Console
- Cloud Console IAM & Admin Service Account
- You can also reach this page from the last screen used in Google Play Console. Click 'Learn how to create service accounts', then 'Google Cloud Platform' from the pop up. This will ensure that you're in the same project that you linked in Step 1 - if using the the links above or another way, double check this before creating the service account.
a. Create and name the service account key credentials and add roles.
Select the button to 'Create Service Account'. These are the credentials that RevenueCat will need to communicate with Google. Name your new account, then select 'Create and continue'.
On the step named 'Grant this service account access to project', you'll add two Roles:
- Pub/Sub Admin - this enables Platform Server Notifications
- Monitoring Viewer - this allows monitoring of the notification queue
Note that searching by name in the filter does not always bring up both roles. You can also find each by scrolling through the list - in the Pub/Sub and Monitoring folders respectively.
You can skip the optional third step, and select done.
b. Create and download the public key
In the 'Service Accounts' section of the Google Cloud Console, select the three dots for the Actions dropdown menu, then Manage Keys.
Select Add Key, then Create new key. On the pop up, make sure JSON is selected, and then create and download the JSON Key. We'll use this in Step 4.
Enable the Pub/Sub API for Google Developer Notifications
While you're in the Google Cloud Console, get a head start on setting up Google real-time developer notifications by ensuring Google Cloud Pub/Sub is enabled for your project. You can enable it here.
3. Grant Financial Access to RevenueCat
- Where: Google Play Console
- Developer homepage 'Setup' section of sidebar API Access
Back in the Google Play Console, on the same screen that we left off on in Step 1, select 'Manage Play Console Permissions' for the service account you created in Step 2. If you don't see the account, try refreshing the page.
a. Grant the following permissions:
- View app information and download bulk reports (read-only)
- View financial data, orders, and cancellation survey response
- Manage orders and subscriptions
All other choices are yours - the other boxes can be checked or unchecked according to your needs, as long as those three are selected.
Select invite user at the bottom of the page, and send the invite. You'll be redirected to 'Users and Permissions', where you should see your newly created account as active.
b. Apply permissions to your apps
In the 'Users and Permissions' section, select the service account and add your app to the account. The sheet that appears confirms the permissions we chose for this user in the last step. Select Apply, then Save Changes.
4. Enter the Credentials JSON in RevenueCat
- Where: RevenueCat Dashboard
- Project Page Google Play App Settings
Find your credentials JSON file that was downloaded in Step 2 and either drop it into your project settings or select it from the finder. Be sure to save changes. Within approximately 36 hours, your credentials will be activated and we’ll be ready to handle Google Play purchases!
There is a workaround to get this validated sooner. In Google Play Console, open your app's dashboard and visit the 'Monetize' section. Go to Products -> Subscriptions/in-app products, and change the description of any product and save the changes. This should work to enable the new service credentials right away (or very shortly) and you can revert the changes to that product. It's not guaranteed to work, but has worked for others in the past to get things working right away. Otherwise, it usually starts working within 24 hours but possibly more than 36.
While you’re in your RevenueCat Play Store App settings and waiting for your credentials to activate, set up your Google Real-Time Developer Notifications. If you enabled Pub/Sub in Step 2 of this doc, skip ahead to step 2 of the setup.
This guide contains a lot of information and many steps, and it can be all too easy to move too quickly or simply misconfigure something. Break down each step by where it needs to take place as you're going through the guide or after the fact with our handy Checklist.
Commonly occurring errors when setting up your service credentials or developer notifications and what to do when you see them.
|Error:||Underlying message:||What to do:|
|'Your Google Service Account credentials do not have permissions to access the needed Google resources. Refer to this guide for more information.'||Confirm that the roles granted to your service account in Google Cloud match: Pub/Sub Admin and Monitoring Viewer. If you change them or update them at all, make sure that you re-generate your JSON key to add to RevenueCat.|
|'The provided Google Service Account credentials JSON is invalid.'||Re-generate the JSON key from Google Cloud and try uploading it to RevenueCat again. If you get the same error, try re-creating your service account.|
|'Invalid Play Store credentials.'||Unfortunately, this one is a little vague. Run through the guide again, ensuring that all steps have been followed. If you've already waited for over 36 hours and continue to get this error, try starting over from the beginning.|
|'Google Play service account credentials must be set up before using this feature.'||This one is most likely to crop up if trying to perform an action that communicates with Google, such as importing products for Android, before setting up service credentials.|
|'Account permissions are invalid for this request.'||Not all RevenueCat collaborators have the same permissions. In order to make changes to an app's configuration (such as creating service credentials), a user must be listed as an 'Admin'.|
|'Google Play Pub/Sub integration is not currently enabled for this app.'||Enable access to the Pub/Sub API on the Google Cloud Console for the same project that you used to set up your service credentials.|
|'Your Google service account credentials do not have permissions to access the Google Cloud Pub/Sub API. Refer to this guide for more information.'||This points to either the Pub/ Sub API access not being enabled, or the Pub/Sub role that has been added to the service account is not the admin role. Double check that your service account has the correct roles, and if changing them, re-generate the JSON key and re-add it to RevenueCat.|
