Recommendation
We recommend that you refer to this tutorial after you have finished developing your app and have at least drafted your app for the App Store and/or Play Store.In-app purchases are the best way to monetize our mobile applications. App stores like the App Store and Play Store handle payments and manage recurring subscriptions for us.
Instead of integrating with each store separately, there are SaaS solutions specializing in in-app purchases. Our boilerplate includes an integration with RevenueCat, which offers excellent pricing, integrations, and documentation.
In this document, we will explain how to set up RevenueCat. But before start, you need to have Firebase, App Store Connect and/or Play Store Console set up.
RevenueCat Setup
1. First, you need to create an account for free on RevenueCat, if you didn't create one.
2. After signed in, to create a project click on + Create new project button in the Projects dropdown on the RevenueCat dashboard.
3. Set your project name and click save changes.
4. Once you create a project you'll be prompted to add an App. Select the iOS and Android app and follow the configuration steps for those platforms.
Firebase Extension Setup
RevenueCat also offers a highly successful Firebase Extension for free to simplify Firebase integration.
With this extension, your customer information and events from app stores are instantly recorded to your Firestore database.
Subsequently, to check whether a user has access to services you offer exclusively to paid users, you can simply verify it from Firestore on your backend. Another scenario is triggering serverless functions when a document is added to the collection where payment events are written. These functions can be used to send notifications/emails to the user, grant additional rights, add credits, etc.
