Installation

This guide will help you install and configure Expo IAP in your React Native or Expo project.

Prerequisites​

Before installing Expo IAP, make sure you have:

  • React Native 0.64 or later, or Expo SDK 45 or later
  • Node.js 16 or later
  • iOS 12+ for iOS apps
  • Android API level 21+ for Android apps

Package Installation​

Install the package using your favorite package manager:

npm install expo-iap

Platform Configuration​

For Expo Managed Workflow​

If you're using Expo managed workflow, you'll need to create a custom development client since in-app purchases require native modules that aren't available in Expo Go.

  1. Install Expo CLI (if not already installed):

    npm install -g @expo/cli

  2. Create a development build:

    eas build --platform ios --profile development
    eas build --platform android --profile development

For Expo Bare Workflow​

If you're using Expo bare workflow or vanilla React Native, you'll need to install the native dependencies:

iOS​

  1. Install pods:

    cd ios && pod install

  2. Add StoreKit capability to your iOS app in Xcode:

    • Open your project in Xcode
    • Select your app target
    • Go to "Signing & Capabilities"
    • Click "+ Capability" and add "In-App Purchase"

Android​

No additional configuration needed for Android. The Google Play Billing library is automatically linked.

Configuration​

App Store Connect (iOS)​

Before you can use in-app purchases on iOS, you need to set up your products in App Store Connect:

  1. Sign in to App Store Connect
  2. Navigate to your app
  3. Go to "Features" > "In-App Purchases"
  4. Create your products with unique product IDs

Google Play Console (Android)​

For Android, set up your products in Google Play Console:

  1. Sign in to Google Play Console
  2. Navigate to your app
  3. Go to "Monetize" > "Products" > "In-app products"
  4. Create your products with unique product IDs

Verification​

To verify that Expo IAP is properly installed, create a simple test:

import {useIAP} from 'expo-iap';

function TestComponent() {
  const {connected} = useIAP();

  console.log('IAP Connection status:', connected);

  return null;
}

If everything is set up correctly, you should see the connection status logged in your console.

Next Steps​

Now that you have Expo IAP installed, you can:

Troubleshooting​

If you encounter issues during installation:

  1. Clear node_modules and reinstall:

    rm -rf node_modules
    npm install

  2. For iOS, clean and rebuild pods:

    cd ios
    rm -rf Pods Podfile.lock
    pod install

    For Expo projects, use prebuild instead:

    npx expo prebuild --clean

  3. For React Native, reset Metro cache:

    npx react-native start --reset-cache
