Setup RevenueCat

Prerequisites

1. Have an app in Google Play Console and/or App Store Connect.
2. A RevenueCat Account (create one here).
3. A RevenueCat Project configured for Android/iOS (guide).

Tip

Skip the product configurartion step in the Qucikstart guide for now.

Flutter Setup

Once you have the prerequisties, the integration in the app is as simple as adding the Google and/or Apple keys in the app/.env file and build the environment using the build_runner.

KEY_REVENUECAT_GOOGLE=goog_xxxx
KEY_REVENUECAT_APPLE=appl_yyyy

Configure products

Setting up products is the most important step to configure your app but also the most time-consuming. Follow RevenueCat official docs to configure your products.

Tip

Skip this step for now and create test packages using the Firestore packages collection by running the create_payment.sh script.

Configure Webhooks

The payment system uses Firebase Functions to handle webhooks from RevenueCat:

1. Go to https://app.revenuecat.com/settings/webhooks

2. Click the ’+’ button

3. Use your deployed Firebase Function as Webhook URL

   https://LOCATION-PROJECTID.cloudfunctions.net/api/v1/payment/event/rc

4. You can define an “Authorization header value” and check it matches in the function

5. Save webhook.

Tip

Check out RevenueCat’s Testing Webhooks documentation for information on how to test your webhook integration.
