This package provides a Unity IAP store implementation for the Kongregate website. This allows you to easily add support in-app purchases through the Kongregate website if your game is setup to use Unity IAP.

To include kongregate-iap as a Unity package, you'll need to be on Unity 2018.3 or later. Open Packages/manifest.json in your project and add "com.kongregate.kongregate-iap" to the "dependencies" object:

{
  "dependencies": {
    "com.kongregate.kongregate-iap": "https://github.com/randomPoison/kongregate-iap.git"
  }
}

NOTE: You'll need to have Git installed on your development machine for Unity to be able to download the dependency. See https://git-scm.com/ for more information.

NOTE: If you're using an older version of Unity, you can still use kongregate-iap by copying the contents of Scripts into your project's Assets folder.

kongregate-iap depends on the kongregate-web package, which requires additional setup. If you're not already using kongregate-web directly, follow the kongregate-web setup instructions in order to get started.

When initializing Unity IAP, provide KongregatePurchasingModule.Instance() to ConfigurationBuilder.Instance() in order to setup the Kongregate store on WebGL:

var builder = ConfigurationBuilder.Instance(
    KongregatePurchasingModule.Instance(),
    StandardPurchasingModule.Instance());

The basic setup described will always configure your game to use the Kongregate store when building a WebGL player. However, if you need more control over when you use the Kongregate store on WebGL, you can create a custom store module to do so. In your custom module's Configure() method, you should register KongregateStore as follows:

public override void Configure()
{
    RegisterStore(
        KongregateStore.STORE_NAME,
        UseKongregateStore ? new KongregateStore() : null);

    // Register any other stores...
}

When using the Kongregate store, the Store field in the purchase receipt is "Kongregate". The Payload field is a JSON-encoded string containing the following fields:

• AuthToken: string - The authorization token for the user who made the purchase.
• Items: int[] - An array of unique item IDs.

You can use UnityEngine.JsonUtility.FromJson() to deserialize Payload into an instance of KongregateStore.Receipt if you need to inspect its contents.
