Paymentwall Unity SDK allows merchants to accept payments in the games created by Unity.

This tutorial assumes that you have a Paymentwall Merchant Account. Please Sign up if you don’t have one.

Paymentwall SDK for Unity can be downloaded here.

In github, you will be able to find our module-unity. Extract the code from Unity/Paymentwall folder to use the SDK. If you would like to use our demo, the database can be taken from Database folder, and the code will be from Unity/Demo folder.

Integrate payment widget

  • Create a new Unity MonoBehaviour class, add the following code to it. Modify API type and other custom parameters as you like.
using Paymentwall;

public class TestPlugin : MonoBehaviour {

	// Use this for initialization
	void Start () {
		PWBase.SetAppKey("9fa5245253f742e50e705f65b9b02d66"); // your Project Public key - available in your {{ site.brand_payments }} merchant area
		PWBase.SetSecretKey("3918c61450ab7aaa62760036f03eb947"); // your Project Private key - available in your {{ site.brand_payments }} merchant area

		List<PWProduct> productList = new List<PWProduct>();
		PWProduct product = new PWProduct(
			"product301", // id of the product in your system
			9.99f, // price
			"USD", // currency code
			"Gold Membership", // product name
			PWProduct.TYPE_SUBSCRIPTION, // this is a time-based product; for one-time products, use Paymentwall_Product.TYPE_FIXED and omit the following 3 parameters
			1, // time duration
			PWProduct.PERIOD_TYPE_YEAR, // year
			true // recurring
		PWWidget widget = new PWWidget(
			"user40012", // id of the end-user who's making the payment
			"p1_1", // widget code, e.g. p1; can be picked inside of your merchant account
			new Dictionary<string, string>() {{"email", "user@hostname.com"}} // additional parameters
		PWUnityWidget unity = new PWUnityWidget (widget);
		StartCoroutine (unity.callWidgetWebView (gameObject,canvas)); // call this function to display widget
  • You can modify the size and behaviour of payment’s widget in PWUnityWidget.cs.

  • Run Unity Editor (support only on OSX ) or build it to mobile and see your result.
