Unity

Paymentwall’s 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.


Download SDK

Paymentwall’s 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.SetApiType(Paymentwall_Base.API_VC);
		PWBase.SetAppKey("9fa5245253f742e50e705f65b9b02d66"); // your Project Public key - available in your Paymentwall merchant area
		PWBase.SetSecretKey("3918c61450ab7aaa62760036f03eb947"); // your Project Private key - available in your Paymentwall 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
			);
		productList.Add(product);
		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
			productList,
			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.
