• search IAP prefab

• drag and drop IAP prefab into scene

Create IAPScript Script

• create a C# script, named it IAPScript:

using UnityEngine;
using System.Collections;

public class IAPScript : MonoBehaviour {

    private Sdkbox.IAP _iap;

    // Use this for initialization
    void Start () {
        _iap = FindObjectOfType<Sdkbox.IAP>();
        if (_iap == null) {
            Debug.Log("Failed to find IAP instance");
        }
    }

    // Update is called once per frame
    void Update () {
    }

    public void Purchase(string item) {
        if (_iap != null) {
            Debug.Log("About to purchase " + item);
            _iap.purchase(item);
        }
    }

    /*
     * Event Handlers
     */
    public void onInitialized(bool status) {
        Debug.Log("IAPScript.onInitialized " + status);
    }

    public void onSuccess(Sdkbox.Product product) {
        Debug.Log("IAPScript.onSuccess: " + product.name);
    }

    public void onFailure(Sdkbox.Product product, string message) {
        Debug.Log("IAPScript.onFailure " + message);
    }

    public void onCanceled(Sdkbox.Product product) {
        Debug.Log("IAPScript.onCanceled product: " + product.name);
    }

    public void onRestored(Sdkbox.Product product) {
        Debug.Log("IAPScript.onRestored: " + product.name);
    }

    public void onProductRequestSuccess(Sdkbox.Product[] products) {
        foreach (var p in products) {
            Debug.Log("Product: " + p.name + " price: " + p.price);
        }
    }
    public void onProductRequestFailure(string message) {
        Debug.Log("IAPScript.onProductRequestFailure: " + message);
    }
    public void onRestoreComplete(string message) {
        Debug.Log("IAPScript.onRestoreComplete: " + message);
    }

}

Note: this script just handler iap event and purchase, you need handler refresh getProducts, see PurchaseHandler in IAP Sample Scene.

• attach IAPScript to Main Camera, (you can attach IAPScript to another node, it's ok)

• add your android iap items to android products

• fill callback with event handler function in IAPScript

Configure Buy Button

Note: argment of Purchase is the name your iOS/Android product
