Simple IAP System

Android Native plugin provides all required C# API for integration In-App purchases to your project. However if you do not have good scripting knowledge, or simply want to make integration more easier, you can stick with 3-rd party services that will allow you to integrate In-App purchases in your games without writing code at all. In this case you can take a look at the Playmaker Actions section, or take a look at Simple IAP System as more advanced  non-scripting solution for the In-app implementation.

Simple IAP System is working Sema sly in with the Android Native plugin. All you need to do is to have both plugins in the project, and you can implement In-app's using Simple IAP System.
