# Expo IAP

Expo IAP is a powerful in-app purchase solution for Expo and React Native applications that conforms to the Open IAP specification. It provides a unified API for handling in-app purchases across iOS and Android platforms with comprehensive error handling and modern TypeScript support.
If you're shipping an app with expo-iap, we’d love to hear about it—please share your product and feedback in [Who's using Expo IAP?](https://github.com/hyochan/expo-iap/discussions/143). Community stories help us keep improving the ecosystem.

## Notice
The `expo-iap` module has been migrated from [react-native-iap](https://github.com/hyochan/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](https://github.com/hyochan/react-native-iap/discussions/2754) for more details.

## Installation
```bash
npx expo install expo-iap

## Our Sponsors
💼 **[View Our Sponsors](https://openiap.dev/sponsors)**
We're building the OpenIAP ecosystem—defining the spec at [openiap.dev](https://www.openiap.dev), maintaining [OpenIAP](https://github.com/hyodotdev/openiap) for the shared type system, and shipping platform SDKs like [openiap-apple](https://github.com/hyodotdev/openiap/tree/main/packages/apple) and [openiap-google](https://github.com/hyodotdev/openiap/tree/main/packages/google) that power [expo-iap](https://github.com/hyochan/expo-iap), [flutter_inapp_purchase](https://github.com/hyochan/flutter_inapp_purchase), React Native, and [kmp-iap](https://github.com/hyochan/kmp-iap). The work so far has focused on untangling fragmented APIs; the next milestone is a streamlined purchase flow: `initConnection → fetchProducts → requestPurchase → (server receipt validation) → finishTransaction`.
Your sponsorship helps ensure developers across platforms, OS, and frameworks can implement in-app purchases without headaches. It also fuels new plugins, payment systems, and partner integrations already being explored in the OpenIAP community. Sponsors receive shout-outs in every release and can request tailored support depending on tier. If you’re interested—or have rollout feedback to share—you can view sponsorship options at [openiap.dev/sponsors](https://openiap.dev/sponsors).
