In order to use IAP with Google Play Store, you must have an active Google Session, to do this read our or take a look at our in-house feature where you can start a Remote Login Session for Google!
It is presumed that you have at least made an Application in Google Play Console!
Create In App Purchases on Google
To utilize IAP you must make the In App Purchases in .
Some important information to find is your application name; it generally follows this style "com.company.app_name", this name can be found under the overview of all your applications, or inside the application page beneath the title.
Underneath the Monetization page in the left menu list, you will see Products which contains In-app products. This is where you set up your products to use IAP with.
Create new in-app product, supply all the required fields.
Creating Purchases In Engine
To create Purchases in Unity, you must inherit from IDetailedStoreListener and import the required methods that follows.
public void Purchase()
{
var product = controller.products.WithID("<replace_with_product_id>");
if (product is { availableToPurchase: true })
{
controller.InitiatePurchase(product);
}
}
This snippet shows you how you'll connect LootLocker IAP to the flow:
public PurchaseProcessingResult ProcessPurchase(PurchaseEventArgs e)
{
LootLockerIAPManager.RedeemPurchase(e.purchasedProduct);
return PurchaseProcessingResult.Complete;
}
This is the complete script:
using Unity.Services.Core;
using Unity.Services.Core.Environments;
using UnityEngine;
using UnityEngine.Purchasing;
using UnityEngine.Purchasing.Extension;
public class IAPManager : MonoBehaviour, IDetailedStoreListener
{
public IStoreController controller;
private IExtensionProvider extensions;
public async void Awake()
{
try
{
var options = new InitializationOptions()
.SetEnvironmentName("production");
await UnityServices.InitializeAsync(options);
}
catch (Exception exception)
{
Debug.Log(exception);
}
//Specifically creates IAP for Google Play Store, using ifdefs to determine which platform is being run is preferable.
var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance(AppStore.GooglePlay));
builder.AddProduct("<replace_with_product_id>", ProductType.Consumable);
StandardPurchasingModule.Instance().useFakeStoreAlways = true;
UnityPurchasing.Initialize(this, builder);
}
public void OnPurchaseClicked(string productId)
{
controller.InitiatePurchase(productId);
}
public void Purchase()
{
var product = controller.products.WithID("<replace_with_product_id>");
if (product is { availableToPurchase: true })
{
controller.InitiatePurchase(product);
}
}

{
Debug.Log("Error: " + message);
}
}
A guide is currently in the making as this requires a lot of set up! Once the guide is up, it will be linked here.
To be able to redeem a Google purchase you've made, you need to grab the product id (the same you used to make the purchase) and the purchase token from a successful purchase as input for the redeem.
On a successful redemption, the player will have been rewarded with whatever catalog item that this product id has been set up to reward.
