Hi,
I am working on integrating In-App Purchases (IAP) into a React Native app using the Expo managed environment. I would appreciate guidance on the complete implementation steps for setting up and handling IAP in this context.
Specifically, I am looking for:
- How to configure In-App Purchases in App Store Connect (product IDs, pricing, etc.)
- Which libraries or Expo modules are recommended for IAP in a managed Expo workflow (e.g., expo-in-app-purchases or react-native-iap)?
- Step-by-step integration guide — installing the library, adding necessary permissions/entitlements, and any required app.json / app.config.js configuration.
- How to fetch available products, initiate a purchase, and handle purchase callbacks/receipts in code.
- Server-side receipt validation — best practices and recommended approach.
- Handling edge cases such as purchase restoration, subscription renewals, and failed transactions.
- Any sandbox testing setup required for testing IAP before going live.
Any official documentation, sample code, or recommended resources for React Native Expo managed workflow would be greatly appreciated.
Thank you!
