Notice

The expo-iap module has been migrated from react-native-iap. While we initially considered fully merging everything into react-native-iap, we ultimately decided to maintain the two libraries in parallel, each tailored to its own ecosystem.

• react-native-iap → a Nitro Modules–based implementation for React Native.
• expo-iap → an Expo Module with tighter integration and smoother compatibility in the Expo ecosystem.

Both libraries will continue to be maintained in parallel going forward.

📖 See the Future Roadmap and Discussion for more details.

Installation

npx expo install expo-iap

Android Configuration

Important: For Android, expo-iap uses Google Play Billing Library v8.0.0 which requires Kotlin 2.0+. Since expo-modules-core doesn't support Kotlin v2 yet, you need to configure your project with expo-build-properties:

{
  "expo": {
    "plugins": [
      [
        "expo-build-properties",
        {
          "android": {
            "kotlinVersion": "2.0.21"
          }
        }
      ]
    ]
  }
}
