1. To become an Xsolla partner, sign up in Xsolla control panel at this address: https://publisher.xsolla.com/signup/?utm_source=unity&utm_medium=instruction
2. Familiarize yourself with the Integration Guides and select the modules that best fit your project. All the guides contain video tutorials on how to set up a Xsolla control panel for each specific module. You can find the Integration Guides here: https://developers.xsolla.com/#getting-started
3. You have to chose way how to integrate GENERAL INTEGRATION or SIMPLE INTEGRATION.
   • GENERAL - require own backend and IPN realization.
   • SIMPLE - require only created project inside your publisher account but have less functionality.

Features:
- Saved payment methods
- User balance

• Set Up Instant Payment Notification (IPN): http://developers.xsolla.com/api.html#notifications
• Create an Xsolla Access Token to conduct payments with maximum security. You can find documentation on creating a token here: http://developers.xsolla.com/api.html#payment-ui

If you would like to accept payments through Xsolla’s payment UI, follow these steps:

1. Add XsollaSDK script to any object or use prefab from “Resources -> Prefabs” folder or just use XsollaSDKStatic;
2. Call XsollaSDK(instance)to generate ready to use payment form.
3. CreatePaymentForm(token, actionOk(XsollaOkResult), actionError(XsollaError))

• Also you can use XsollaSDK.InitPaystation(string token) function to use our payment solution in native browser.

• If you want have own payment UI you should write own class which extends XsollaPaystation Class. As Example you can use XsollaPaystationController;

Features:

• Backend not required
• Token generation not required
• Less functionality
• Less secure

To use SIMPLE INTEGRATION plase contact our account managers am@xsolla.com

• Add XsollaSDK script to any object or use prefab from “Resources -> Prefabs” folder or just use XsollaSDKStatic;
• Call XsollaSDK(instance)to generate ready to use payment form.
• CreatePaymentForm(xsollaJsonGenerator, actionOk(XsollaOkResult), actionError(XsollaError))

"*" to use mode sandbox for unsigned project, mode and secretKey(your project secretKey) params must be added.

• If you want have own payment UI you should write own class which extends XsollaPaystation Class. As Example you can use XsollaPaystationController;

public class XsollaResult {
    public string invoice{ get; set;}
    public Status status{ get; set;}
    // DONE status mean successful payment
    public Dictionary<string, object> purchases;
    // purchases can contain 
    // Key: «out» - virtual currency      | Value: int amount
    // Key: «id_package» - subscription   | Value: long subscriptionId
    // Key: «sku[itemId]» - virtual items | Value: int amount
}

public class XsollaError {
    public Source errorSource{ get; private set;}
    public int errorCode{ get; private set;}
    public string errorMessage{ get; private set;}
}

If you use Windows OS you must move content from folder XsollaUnitySDK/move_Content_to_project_plugins to folder YOUR_PROJECT/Assets/Plugins. If you don’t have this folder, create it.

You can look demo on https://livedemo.xsolla.com/sdk/unity/
We have two test scenes in "XsollaUnitySDK" -> "Resources" -> "_Scenes" folder:

• XsollaFarmFreshScene - emulates item shop
• XollaTokenTestScene - here you can test your token.
