CI Release Godot 4.3+ OpenIAP License: MIT

A comprehensive in-app purchase plugin for Godot 4.x that conforms to the Open IAP specification

Open IAP

About

This is an In-App Purchase plugin for Godot Engine, built following the OpenIAP specification. This project has been inspired by expo-iap, flutter_inapp_purchase, kmp-iap, and react-native-iap.

We are trying to share the same experience of in-app purchase in Godot Engine as in other cross-platform frameworks. Native code is powered by openiap-apple and openiap-google modules.

We will keep working on it as time goes by just like we did in other IAP libraries.
