SDKs de nível empresarial para Unity

Integre o SDK no lado do aplicativo

  1. Design an interface for the login system, in-game store, and other pages for your application.
  2. Set up event handling according to your application logic using SDK methods. To get started with the basic SDK features, follow the step-by-step tutorials below.
Observação
You can create your own solution by following Unity instructions, or use the demo scene as a template. To adapt the demo scene UI to your application, use the UI builder.
Follow the step-by-step tutorials below to get going with the basic SDK features.

Login de usuário via nome de usuário/e-mail e senha

This instruction shows how to use SDK methods to implement:

  • user sign-up
  • resend request for a sign-up confirmation email
  • user login
  • user password reset

You can authenticate users with their username or email address. In the following examples we authenticate users with their username, whereas the email address is used to confirm sign-up and to reset the password.

Observação
If you use the Login widget on your site (in a web store, for example), make sure that you implemented the same user authentication methods on your site and in your application. The widget uses the email address for authentication by default. To set up user login via username, contact your Account Manager.

The logics and interface in the examples are less complicated than they will be in your application. A possible authentication system implementation option is described in the demo project.

Implemente o cadastro de usuários

This tutorial describes the implementation of the following logic:

Crie uma interface de página

Create a scene for a sign-up page and add the following elements on it:

  • username field
  • user email address field
  • user password field
  • sign-up button

The following picture shows the example of a page structure.

Crie um controlador de página

  1. Create a script RegistrationPage inherited from the MonoBehaviour base class.
  2. Declare variables for the page interface elements and set values for them in the Inspector panel.
  3. Add logics to process clicking on the sign-up button:
    1. In the Start method, subscribe to a clicking event.
    2. Add an anonymous method that is called after clicking the button.
    3. In this method, declare the username, email, and password variables and initialize them by the values from the fields on the page.
    4. Call the XsollaAuth.Instance.Register SDK method and pass the username, email, and password variables and the following methods to it:
      • OnSuccess — called if sign-up is successful
      • OnError — called if an error occurs
Observação

In the script’s examples, the OnSuccess and OnError methods call the standard Debug.Log method. The error code and description are passed in the error parameter.

You can add other actions like opening a page with a resend request for a sign-up email or opening a login page if sign-up is successful.

Example of a script for a sign-up page:

Copy
Full screen
Small screen
using UnityEngine;
using UnityEngine.UI;
using Xsolla.Auth;
using Xsolla.Core;

namespace Recipes
{
	public class RegistrationPage : MonoBehaviour
	{

		[SerializeField] private InputField UsernameInput;

		[SerializeField] private InputField EmailInputField;

		[SerializeField] private InputField PasswordInputField;

		[SerializeField] private Button RegisterButton;

		private void Start()
		{
			// Handling the button click
			RegisterButton.onClick.AddListener(() =>
			{
				var username = UsernameInput.text;
				var email = EmailInputField.text;
				var password = PasswordInputField.text;

				XsollaAuth.Instance.Register(username, password, email, onSuccess: OnSuccess, onError: OnError);
			});
		}

		private void OnSuccess()
		{

			// Some actions
		}

		private void OnError(Error error)
		{
			UnityEngine.Debug.Log($"Registration failed. Description: {error.errorMessage}");
			// Some actions
		}
	}
}

Configure o email de confirmação de cadastro

After successful sign-up, a user receives a sign-up confirmation email to a specified address. You can customize emails sent to users in Publisher Account.

If you are developing an Android application, set up deep links to return a user to an application after they confirm sign-up.

Observação
You can disable sign-up confirmation via an email address if your security standards allow you to do this. Contact your Account Manager to disable it or contact us at csm@xsolla.com.

Login social

This guide shows how you can use SDK methods to implement user sign-up and login via their social network account.

Unlike for user authentication via username/user email address and password, you don’t have to implement separate logics for user sign-up. If the user’s first login is via a social network, a new account is created automatically.

If you have implemented social login in your application as an alternative authentication method, the social network account automatically links to an existing user account if the following conditions are met:

  • A user who signed up with username/email address and password logged into your application via a social network account.
  • A social network returns an email address.
  • User email address in a social network is the same as the email address used for sign-up in your application.
Observação
You can implement manual linking of a social network account. Add the page to your application where users can link a social network account to their account. In the page controller, use the LinkSocialProvider SDK method.

This tutorial describes the implementation of the following logic:

The examples show how to set up user login via a Twitter account. You can set up all social networks in the same way.

The logics and interface in the examples are less complicated than they will be in your application. A possible authentication system implementation option is described in the demo project.

Crie uma interface de página

Create a scene for a login page and add the social login button to it. The following picture shows an example of the page structure.

Crie um controlador de página

  1. Create a script SocialAuthorizationPage inherited from the MonoBehaviour base class.
  2. Declare variables for the application login page interface elements and set values for them in the Inspector panel.
  3. Add logics to process clicking on the login button:
    1. In the Start method, subscribe to a clicking event.
    2. Add an anonymous method that is called after clicking the button.
    3. To pass a login page URL, declare the url variable in an anonymous method. Initialize this variable by the GetSocialNetworkAuthUrl SDK method by passing a Facebook value in the SocialProvider parameter.
    4. To open a browser, call the BrowserHelper.Instance.Open method. To use a built-in browser, pass the url variable and a true value to the method.
Observação
Social login isn’t available for external browsers. SDK contains a built-in browser developed by Xsolla. You can use either an Xsolla built-in browser or a different built-in browsing solution.
    1. To get a token and close the browser, track the changes of the page URL after successful user sign-up:
      1. Declare a singlePageBrowser variable and initialize it via the BrowserHelper.Instance.GetLastBrowser SDK method.
      2. Subscribe to an active page URL changing event and set the OnUrlChanged method as a handler.
  1. Implement getting of the token:
    1. Use a ParseUtils.TryGetValueFromUrl utility method to parse a URL of an active page passed in the OnUrlChanged method.
    2. Add a check for an authentication code in an active page URL. The ParseUtils.TryGetValueFromUrl method passes an authentication code in the code variable.
    3. To exchange an authentication code for a token, call the ExchangeCodeToToken SDK method and pass a code variable and the following methods to it:
      • OnSuccess — called if sign-up is successful
      • OnError — called if an error occurs
Observação

In the script’s examples, the OnSuccess and OnError methods call the standard Debug.Log method. You can add other actions.

If a user successfully logs in, the authorization token is passed in the token parameter. This token is used in requests to Xsolla servers. If an error occurs, its code and description are passed in the error parameter.

    1. After you get the token, delete a game object with a browser.

Example of a script for a login page:

Copy
Full screen
Small screen
using UnityEngine;
using UnityEngine.UI;
using Xsolla.Auth;
using Xsolla.Core;

namespace Recipes
{
	public class SocialAuthorizationPage : MonoBehaviour
	{
		// Declaration of variables for UI elements on the page

		[SerializeField] private Button FacebookButton;

		private void Start()
		{
			// Handling the button click

			FacebookButton.onClick.AddListener(() =>
			{
				// Opening browser

				var url = XsollaAuth.Instance.GetSocialNetworkAuthUrl(SocialProvider.Facebook);
				BrowserHelper.Instance.Open(url, true);

				// Determining the end of authentication
				BrowserHelper.Instance.InAppBrowser.AddUrlChangeHandler(OnUrlChanged);
			});
		}

		// Getting token
		private void OnUrlChanged(string url)
		{
			if (ParseUtils.TryGetValueFromUrl(url, ParseParameter.code, out var code))
			{
				XsollaAuth.Instance.ExchangeCodeToToken(code, OnSuccess, OnError);
				BrowserHelper.Instance.Close();
			}
		}

		private void OnSuccess(string token)
		{
			UnityEngine.Debug.Log($"Authorization successful. Token: {token}");
			// Some actions
		}

		private void OnError(Error error)
		{
			UnityEngine.Debug.Log($"Authorization failed. Description: {error.errorMessage}");
			// Some actions
		}
	}

Exibição do catálogo de itens

This tutorial shows how to use the SDK methods to display the following items in an in-game store:

  • virtual items
  • groups of virtual items
  • bundles
  • packages of virtual currency

Before you start, configure items in Publisher Account:

  1. Configure virtual items and groups of virtual items.
  2. Configure packages of virtual currencies.
  3. Configure bundles.

This tutorial describes the implementation of the following logic:

The logics and interface in the examples are less complicated than they will be in your application. A possible item catalog in an in-game store implementation option is described in the demo project.

Observação

The example of every item in a catalog shows:

  • item name
  • item description
  • item price
  • image

You can also show other information about the item if this information is stored in an in-game store.

Implemente a exibição de itens virtuais

Crie um widget de item

  1. Create an empty game object. To do this, go to the main menu and select GameObject > Create Empty.
  2. Convert the created game object in a prefab by dragging a game object from a Hierarchy panel to a Project panel.
  3. Select a created prefab and click Open Prefab in the Inspector panel.
  4. Add the following UI elements as prefab child objects and configure their visuals:
    • item background image
    • item name
    • item description
    • item price
    • item image

The following picture shows an example of the widget structure.

Crie o script do widget de item

  1. Create a script VirtualItemWidget inherited from the MonoBehaviour base class.
  2. Declare variables for the item widget interface elements and set values for them in the Inspector panel.

Example of the widget script:

Copy
Full screen
Small screen

using UnityEngine;
using UnityEngine.UI;

namespace Recipes
{
	public class VirtualItemWidget : MonoBehaviour
	{
		// Declaration of variables for UI elements

		public Text NameText;

		public Text DescriptionText;

		public Text PriceText;

		public Image IconImage;
	}
}

Crie uma página para exibir a lista de itens

  1. On the scene, create an empty game object. To do this, go to the main menu and select GameObject > Create Empty.
  2. Add the following UI elements as prefab child objects and configure their visuals:
    • page background image
    • item widgets display area

The following picture shows an example of the page structure.

Crie um controlador de página

  1. Create a script VirtualItemsPage inherited from the MonoBehaviour base class.
  2. Declare the following variables:
    • WidgetsContainer — container for widgets
    • WidgetPrefab — item widget prefab
  1. Attach a script to a page game object:
    1. Select an object in a Hierarchy panel.
    2. In the Inspector panel, click Add Component and select a VirtualItemsPage script.
  2. Set values for variables in the Inspector panel.
  1. Add login logics by calling an XsollaAuth.Instance.SignIn SDK method in the Start method and pass to it:
    • a username or email address in the username parameter
    • a user password in the password parameter
Observação
In the script example to login we use the credentials of a demo account (username: xsolla, password: xsolla).
    • a flag in the rememberUser parameter for remembering an account
    • the OnAuthenticationSuccess callback method for successful user login
    • the OnError callback method for an error
  1. Add logics for getting the list of items. In the OnAuthenticationSuccess method call the XsollaCatalog.Instance.GetCatalog SDK method and pass to it:
    • a Project ID in the projectId parameter
Observação
You can find the Project ID in Project settings in Publisher Account. In the script example, we passed the value from the SDK settings to a parameter.
    • the OnItemsRequestSuccess for successful operation of getting a list of items
    • the OnError callback method for an error
    • an offset based on the first item in the list in the offset parameter
    • the number of loaded items in the limit parameter
Observação
The offset and limit parameters are not required. Use them to implement pagination — a page-by-page display of items in the catalog. The maximum number of items on the page is 50. If the catalog has more than 50 items, pagination is necessary.
  1. In the OnItemsRequestSuccess method, add logics for creating a widget for every received item:
    1. Instantiate a prefab of item widget as a container child object.
    2. Attach the received VirtualItemWidget component to a widget variable.
  1. Pass the following data to the item widget:
    1. Pass the storeItem.name variable value to the element with the item name.
    2. Pass the storeItem.description variable value to the element with the item description.
    3. Implement the following logics to display the item price:
      • If the value of the storeItem.price variable doesn’t equal null, the item is sold for real currency. Specify the price in the {amount} {currency} format and pass it to the widget element.
      • If the value of the storeItem.virtual_prices variable doesn’t equal null, the item is sold for virtual currency. Specify the price in the {name}: {amount} format and pass it to the widget element.
Observação
The storeItem.virtual_prices variable is an array of prices for the same item in different currencies. The example shows a price specified by default in the item settings in Store > Virtual items in Publisher Account.
    1. To display an item image, use the ImageLoader.Instance.GetImageAsync utility method and pass to it:
      • Image URL.
      • An anonymous function as a callback. In this function, add a received sprite as an item image.

Example of a page controller script:

        // Declaration of variables for containers and widget prefabs

        public Transform WidgetsContainer;

        public GameObject WidgetPrefab;

        private void Start()
        {
            // Starting the authentication process

            XsollaAuth.Instance.SignIn("xsolla", "xsolla", true, null, null, OnAuthenticationSuccess, OnError);
        }

        private void OnAuthenticationSuccess(string token)
        {
            // After successful authentication starting the request for catalog from store

            XsollaCatalog.Instance.GetCatalog(XsollaSettings.StoreProjectId, OnItemsRequestSuccess, OnError, offset: 0, limit: 50);
        }

        private void OnItemsRequestSuccess(StoreItems storeItems)
        {
            // Iterating the items collection and assign values for appropriate ui elements

            foreach (var storeItem in storeItems.items)
            {
                var widgetGo = Instantiate(WidgetPrefab, WidgetsContainer, false);
                var widget = widgetGo.GetComponent<VirtualItemWidget>();

                widget.NameText.text = storeItem.name;
                widget.DescriptionText.text = storeItem.description;

                if (storeItem.price != null)
                {
                    var realMoneyPrice = storeItem.price;
                    widget.PriceText.text = $"{realMoneyPrice.amount} {realMoneyPrice.currency}";
                }
                else if (storeItem.virtual_prices != null)
                {
                    var virtualCurrencyPrice = storeItem.virtual_prices.First(x => x.is_default);
                    widget.PriceText.text = $"{virtualCurrencyPrice.name}: {virtualCurrencyPrice.amount}";
                }

                ImageLoader.Instance.GetImageAsync(storeItem.image_url, (url, sprite) => widget.IconImage.sprite = sprite);
            }
        }

        private void OnError(Error error)
        {
            UnityEngine.Debug.LogError($"Error message: {error.errorMessage}");

You can find the Project ID in Project settings in Publisher Account. In the script example, we passed the value from the SDK settings to a parameter.
    • the OnItemsRequestSuccess for successful operation of getting a list of items
    • the OnError callback method for an error
    • an offset based on the first item in the list in the offset parameter
    • the number of loaded items in the limit parameter
Observação
The offset and limit parameters are not required. Use them to implement pagination — a page-by-page display of items in the catalog. The maximum number of items on the page is 50. If the catalog has more than 50 items, pagination is necessary.
  1. In the OnItemsRequestSuccess method, add logics for forming a list of item groups:
    1. Get the list of unique groups from a received item list. Add to it the All element that will show all items not dependent on their category.
    2. Clear the buttons container by deleting all child objects. To do this, call the DeleteAllChildren method and pass a container object to it.
    3. For every item group:
      1. Instantiate a prefab of item widget as a container child object.
      2. Set the received VirtualItemGroupButton component to the groupButton variable.
      3. Pass the groupName variable value to the element with a group name.
      4. Add an anonymous method to the action of clicking the button. In this method, call the OnGroupSelected method and pass the name of the item group and the list of items as parameters.
    1. To display all items call the OnGroupSelected method and pass All as a group name.
  1. In the OnGroupSelected method, add logics for initial display of items:
    1. Create the itemsForDisplay variable and assign all received items to it if the name of the item group has All. Otherwise, link items that the group name matches with the groupName variable to the itemsForDisplay variable.
    2. Clear the buttons container by deleting all child objects. To do this, call the DeleteAllChildren method and pass a container object to it.
  1. Add logics for creating a widget for every received item:
    1. Instantiate a prefab of item widget as a container child object.
    2. Attach the received VirtualItemWidget component to a widget variable.
  1. Pass the following data to the item widget:
    1. Pass the storeItem.name variable value to the element with the item name.
    2. Pass the storeItem.description variable value to the element with the item description.
    3. Implement the following logics to display item price:
      • If the value of the storeItem.price variable doesn’t equal null, the item is sold for real currency. Specify the price in the {amount} {currency} format and pass it to the widget element.
      • If the value of the storeItem.virtual_prices variable doesn’t equal null, the item is sold for virtual currency. Specify the price in the {name}: {amount} format and pass it to the widget element.
Observação
The storeItem.virtual_prices variable is an array of prices for the same item in different currencies. The example shows a price specified by default in the item settings in Store > Virtual items in Publisher Account.
    1. To display an item image, use the ImageLoader.Instance.GetImageAsync utility method and pass to it:
      • Image URL.
      • An anonymous function as a callback. In this function, add a received sprite as an item image.

Venda itens virtuais por moedas reais

This instruction shows how to use the SDK methods to implement selling of virtual items for real currency.

Before you start, implement a display of virtual items in a catalog. In the following example, we describe how to implement purchasing of virtual items. Configuration for other item types is similar.

This tutorial describes the implementation of the following logic:

The logic and interface in the examples are less complicated than they will be in your application. A possible implementation option for selling items for real currency and displaying a catalog of items is described in the demo project.

Complete o widget de item

Add a purchase button to the item widget and configure its visuals.

The following picture shows an example of the widget structure.

Complete o script do widget de item

  1. Open the VirtualItemWidget script.
  2. Declare variables for the purchase button and set values for them in the Inspector panel.

Example of the widget script:

Copy
Full screen
Small screen
using UnityEngine;
using UnityEngine.UI;

namespace Recipes
{
	public class VirtualItemWidget : MonoBehaviour
	{
		// Declaration of variables for UI elements

		public Text NameText;

		public Text DescriptionText;

		public Text PriceText;

		public Image IconImage;

		public Button BuyButton;
	}
}

Complete o controlador de página para mostrar a lista de itens

  1. Open the VirtualItemsPage script.
  2. In the OnAuthenticationSuccess method, pass the authorization token to the Token.Instance variable.
Observação
You can use one of the following tokens:
  1. Add logic for processing clicking on the virtual item purchase button:
    1. In the OnItemsRequestSuccess method, subscribe to the button-clicking event.
    2. Add an anonymous method that is called after the button is clicked.
    3. In this method, call the XsollaCatalog.Instance.PurchaseItem SDK method to form an order and pass to it:
      • a Project ID in the projectId parameter
      • an item identifier in the itemSku parameter
      • the OnOrderCreateSuccess method to process a successful forming of the item purchase order
      • the OnError callback method for an error
  1. Implement opening of a payment page. To do this, add the OnOrderCreateSuccess method and call in it:
    • the XsollaOrders.Instance.OpenPurchaseUi SDK method, to open a payment page
    • the TrackOrderStatus coroutine, to track changes in the order status
Observação
By default, the payment page opens in a built-in browser. To open it in an external browser, go to Window > Xsolla > Edit Settings in the Unity editor main menu and uncheck the Enable in-app browser? box in the Inspector panel. If you use the external browser for Android apps, we recommend setting up the deep links to redirect the user to the app after they make a payment.
  1. In the TrackOrderStatus coroutine, implement getting the info about the order status one time per second. To do this, use the XsollaOrders.Instance.CheckOrderStatus SDK method and pass to it:
    • a Project ID in the projectId parameter
    • an order number from payment details in the orderId parameter
    • an anonymous method for processing successful receiving of order status info
    • an anonymous method for error processing
  1. In the method for processing successful receiving of order status info, implement the callback of an OnPurchaseSuccess method during the payment for the order (payment status done or paid).
  2. In the OnPurchaseSuccess method, implement the processing of a successful virtual item purchase.
Observação

In the script example, we call the Debug.Log base method if the item purchase is successful. You can add other actions like inventory display, etc.

Implementation of logic for adding purchased items to the inventory isn’t required — it’s done automatically.

  1. If you use a built-in browser for opening a payment page, close this browser.

      • a Project ID in the projectId parameter
      • an item identifier in the itemSku parameter
      • the OnOrderCreateSuccess method to process a successful forming of the item purchase order
      • the OnError callback method for an error
  1. In the OnOrderCreateSuccess method, implement the order status check process. To do this, use the XsollaOrders.Instance.CheckOrderStatus SDK method and pass to it:
    • a Project ID in the projectId parameter
    • an order number from payment details in the orderId parameter
    • an anonymous method for processing successful receiving of order status info
    • an anonymous method for error processing
  1. In the method for processing successful receiving of order status info, implement the callback of an OnPurchaseSuccess method during the payment for the order (payment status done or paid).
  2. In the OnPurchaseSuccess method, implement the processing of a successful virtual item purchase.
Observação

In the script example, we call the Debug.Log base method if the item purchase is successful. You can add other actions like inventory display, virtual currency balance change, etc.

Implementation of logic for adding purchased items to the inventory isn’t required — it’s done automatically.

Exibição do saldo de moedas virtuais

This tutorial shows how to use the SDK methods to display the balance of virtual currency in your app.

The logics and interface in the examples are less complicated than they will be in your application. A possible item catalog in an in-game store implementation option is described in the demo project.

Crie o widget para exibição de saldo

  1. Create an empty game object. To do this, go to the main menu and select GameObject > Create Empty.
  2. Convert the created game object in a prefab by dragging a game object from a Hierarchy panel to a Project panel.
  3. Select a created prefab and click Open Prefab in the Inspector panel.
  4. Add the following UI elements as prefab child objects and configure their visuals:
    • widget background image
    • virtual currency name
    • virtual currency quantity
    • virtual currency image

The following picture shows an example of the widget structure.

Crie o script do widget para exibir o saldo

  1. Create a script VirtualCurrencyWidget inherited from the MonoBehaviour base class.
  2. Declare variables for the item widget interface elements and set values for them in the Inspector panel.

Example of the widget script:

Copy
Full screen
Small screen
using UnityEngine;
using UnityEngine.UI;

namespace Recipes
{
    public class VirtualCurrencyWidget : MonoBehaviour
    {
        // Declaration of variables for UI elements

        public Text NameText;

        public Text AmountText;

        public Image IconImage;
    }
}

Crie uma página com uma lista de moedas virtuais

  1. On the scene, create an empty game object. To do this, go to the main menu and select GameObject > Create Empty.
  2. Add the following UI elements as prefab child objects and configure their visuals:
    • page background image
    • widgets display area

The following picture shows an example of the page structure.

Crie o controlador para a página com a lista de moedas virtuais

  1. Create a script VirtualCurrenciesPage inherited from the MonoBehaviour base class.
  2. Declare the following variables:
    • WidgetsContainer — container for widgets
    • WidgetPrefab — balance display widget prefab
  1. Attach a script to a page game object:
    1. Select an object in a Hierarchy panel.
    2. In the Inspector panel, click Add Component and select a VirtualCurrenciesPage script.
  1. Set values for variables in the Inspector panel.
  2. Add login logics by calling an XsollaAuth.Instance.SignIn SDK method in the Start method and pass to it:
    • a username or email address in the username parameter
    • a user password in the password parameter
Observação
In the script example, to login we use the credentials of a demo account (username: xsolla, password: xsolla).
    • a flag in the rememberUser parameter for remembering an account
    • the OnAuthenticationSuccess callback method for successful user login
    • the OnError callback method for an error
  1. Add logics of getting a list of virtual currencies. To do this, in the OnAuthenticationSuccess method:
    1. Pass the authorization token to the Token.Instance variable.
Observação
You can use one of the following tokens:
    1. Call the XsollaInventory.Instance.GetVirtualCurrencyBalance SDK method and pass to it:
      • the Project ID in the projectId parameter
Observação
You can find the Project ID in Project settings in Publisher Account. In the script example, we passed the value from the SDK settings to a parameter.
      • the OnBalanceRequestSuccess method for successful operation of getting a list of items
      • the OnError callback method for an error
  1. In the OnBalanceRequestSuccess method, add logics for creating a widget for every received virtual currency:
    1. Instantiate a prefab of item widget as a container child object.
    2. Attach the received VirtualCurrencyWidget component to a widget variable.
  1. Pass the following data to the balance widget:
    1. Pass the balanceItem.name variable value to the element with the virtual currency name.
    2. Pass the balanceItem.amount.ToString() variable value to the element with the quantity of the virtual currency.
    3. Implement the following logics to display the item price. To show a virtual currency image, use the ImageLoader.Instance.GetImageAsync utility method, and pass to it:
      • The image URL.
      • An anonymous callback function. In this function, set the received sprite as a virtual currency image.

Example of the page controller script:

Copy
Full screen
Small screen
using UnityEngine;
using Xsolla.Auth;
using Xsolla.Core;
using Xsolla.Inventory;

namespace Recipes
{
	public class VirtualCurrenciesPage : MonoBehaviour
	{

		public Transform WidgetsContainer;

		public GameObject WidgetPrefab;

		private void Start()
		{
			// Starting the authentication process

			XsollaAuth.Instance.SignIn("xsolla", "xsolla", true, null, null, OnAuthenticationSuccess, OnError);
		}

		private void OnAuthenticationSuccess(string token)
		{
			// After successful authentication starting the request for virtual currencies

			Token.Instance = Token.Create(token);
			XsollaInventory.Instance.GetVirtualCurrencyBalance(XsollaSettings.StoreProjectId, OnBalanceRequestSuccess, OnError);
		}

		private void OnBalanceRequestSuccess(VirtualCurrencyBalances balance)
		{
			// Iterating the virtual currencies list and assign values for appropriate ui elements

			foreach (var balanceItem in balance.items)
			{
				var widgetGo = Instantiate(WidgetPrefab, WidgetsContainer, false);
				var widget = widgetGo.GetComponent<VirtualCurrencyWidget>();

				widget.NameText.text = balanceItem.name;
				widget.AmountText.text = balanceItem.amount.ToString();

				ImageLoader.Instance.GetImageAsync(balanceItem.image_url, (url, sprite) => widget.IconImage.sprite = sprite);
			}
		}

		private void OnError(Error error)
		{
			UnityEngine.Debug.LogError($"Error message: {error.errorMessage}");
		}
	}
}

The following picture shows the result of the script’s work.
