IAP integration

Learn in-app purchase integration with Unity IAP.

What Is IAP Integration?

In-App Purchase (IAP) allows players to purchase digital products or features inside a game. Unity IAP is a Unity solution used to connect store purchasing processes to a game project. Products are commonly defined as consumables, non-consumables, or subscriptions.

Product:
  ID: gems_pack
  Type: Consumable

Purchases are processed through real store accounts and the rules of the relevant platform.

Defining Store Products

In IAP integration, each product has a unique product identifier. This identifier allows the game to match the product with the store item. For example, a package that grants in-game gems can be identified with an ID such as gems_pack.

Product ID: gems_pack
Product Type: Consumable
Description: 100 gems

The product type affects whether the purchase can be repeated and how the product is delivered.

Exercise Simulate a Purchase Request

Create a MonoBehaviour class named PurchaseExample. In the Start method, assign the product ID gems_pack to a variable. Then call a method named PurchaseProduct with that ID. The method should print a message indicating a purchase request. This example simulates the flow and does not perform a real store transaction.

Show example solution

using UnityEngine;

public class PurchaseExample : MonoBehaviour
{
    void Start()
    {
        string productId = "gems_pack";
        PurchaseProduct(productId);
    }

    void PurchaseProduct(string id)
    {
        Debug.Log("Purchase requested: " + id);
    }
}
