この拡張機能の動作

RevenueCat’s app monetization platform empowers developers to confidently deploy in-app purchases and subscriptions, centralize data, and grow revenue. RevenueCat builds and adapts to the ever-changing needs of in-app purchase infrastructure, freeing app businesses to invest their time and resources in growing their product.

Install this extension to use Firebase services as your RevenueCat backend for in-app purchases on Apple App Store, Google Play Store, and Amazon Appstore.

The extension makes in-app purchases and subscriptions, controls access to premium content, and syncs customer purchase information to Firestore using RevenueCat.

This extension can:

  • Store purchase lifecycle events (e.g., trial starts, purchases, subscription renewals, billing issues) in Firestore and react to them.
  • Store and update information about customers and their purchases in Firestore.
  • Update information about customers' entitlements as Firebase Authentication Custom Claims.

RevenueCat supports both native iOS and Android apps as well as hybrid cross-platform apps in React Native, Flutter, Unity, Cordova, and Ionic.

You need to create a RevenueCat account or already have one set up to use this extension.

Events

This extension emits events, which allows you to listen to and run custom logic at different trigger points during the functioning of the extension. For example you can listen to events when a new subscription has been purchased via the initial_purchase event, or whenever a subscription or non-renewing purchase has been cancelled through the cancellation event.
