OpenIAP is now ready for the broader IAP ecosystem
React Native IAP v14.0.0 — Reborn with New Architecture Support
About
- Client Protocol: the purchase API every SDK implements.
- Commerce Protocol: the server-side contract backends implement.
- Native packages: openiap-apple (StoreKit 2) and openiap-google (Google Play Billing, Amazon Appstore, Meta Horizon).
- SDKs for React Native, Expo, Flutter, Kotlin Multiplatform, Godot and .NET MAUI, with examples and documentation.
- Conformance tests for checking implementations against the specifications.
- IAPKit, a hosted purchase verification service at kit.openiap.dev. It is free within fair-use limits, and its source is open (MIT), so anyone can host it.
What your support pays for
It is also meant to cover IAPKit's running costs, and the plan is to share those costs openly here as usage grows. An organization whose load strains IAPKit's shared servers may be removed from the shared pool; to keep using it, sponsorship may be required, or it can host IAPKit itself.
Thank you to every sponsor, backer and contributor.
