  • Social login

    In your application, you can implement user authentication using their account in social networks. If the user’s first login is via a social network, a new account is created automatically. The user doesn't need to enter a username, email address, or other data.

    There are two ways to implement authentication through social networks:

    • Web-based authentication. In this case, the application opens a form in the browser to complete authentication via the selected social network.
    • Native authentication. In this case, authentication is performed via the social network application on the user’s device. This option is only suitable for mobile applications.

    Social login can be your application’s primary or alternative authentication method.

    If you use social login 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 a username/email address and password logged into your application via a social network account.
    • A social network returns an email address.
    • The user’s email address in a social network matches the email address used to sign up in your application.

    You can also implement manual linking of a social network account.

    How to set up web-based authentication via social networks

    SDK supports the following providers for social login:

    • Amazon
    • Apple
    • Baidu
    • Battle.net
    • Discord
    • Facebook
    • GitHub

    • VK
    • Vimeo
    • WeChat
    • Weibo
    • Xbox Live
    • Yahoo
    • Yandex
    • YouTube

    To set up authentication through web services:

    1. In the application interface, add buttons for authentication via social networks.
    2. Set up social connections for a Login project in Publisher Account.
    3. Implement authentication logic on the application side.

    Set up social connections for Login project in Xsolla Publisher Account

    Notice
    In Publisher Account, ensure the Classic login and Social login option are selected for the Login project that you use in your application. You can change the login method later by clicking the Change Login method link. Previously saved settings will not be lost.

    1. Open your project in Publisher Account.
    2. In the side menu, сlick Login.
    3. Click Configure in the panel of a Login project.
    4. On the navigation page, go to the Authentication block and select the Social login section.

    1. Connect social networks that users can use to sign up and log into the application:

      • To connect a social network, click the ⚙ icon and select Connect.

      • To connect several social networks at once, select the required panes (their borders will turn green). Then, from the Manage drop-down menu, select Connect.

      • To connect all available social networks, click Select all. Then, from the Manage drop-down menu, select Connect.

    Note
    Xsolla's Application ID and secret key are used for authentication by default. If your application is set up using a developer account of the social provider, you can specify your own Application ID and secret key. Detailed instructions for locating the Application ID and secret are available in the social network card settings in Publisher Account.

    Integrate on application side

    Implement the following logic when clicking the social login button:

    1. Get the sign-up/login page URL using the GetSocialNetworkAuthUrl SDK method.
    2. Open the sign-up/login page in a browser.

    Note
    Social login isn’t available for external browsers. The SDK contains a built-in browser developed by Xsolla. You can either use Xsolla’s built-in browser or a different built-in browsing solution that allows you to track URL changes.

    1. Track the page URL change after successful user authentication.
    2. Get the authentication code from the URL of the active page. You can use the SDK helper method ParseUtils.TryGetValueFromUrl() to do this.
    3. Exchange the authentication code for a token using the ExchangeCodeToToken SDK method.

    How to set up native authentication via social networks

    Native authentication lets users log in to your application via a social network account configured on a mobile device.

    The first time a user logs in, the social networking application is launched and asks for permission to authenticate the user. After that, authentication is performed automatically without requiring the user to do anything.

    Currently, SDK has implemented native authentication via the following social networks:

    • Google
    • Facebook
    • WeChat
    • QQ

    To configure native authentication:

    1. In the application interface, add buttons for authentication via social networks.
    2. Create your Unity project build for Android.
    3. Configure the application in the developer account for the social network:
      1. For authentication via Facebook:
        1. Register and create a new application.
        2. Set up the application page in your Facebook developer account.
      2. For authentication via Google, set up the project in Google API Console.
      3. For authentication via WeChat:
        1. Register and create a new application.
        2. Submit the application for review.
      4. For authentication via QQ:
        1. Register and create a new application.
        2. Submit the application for review.

    1. Set up authentication via social networks on the Xsolla side:
      1. For Facebook and Google, set up social connections in Publisher Account.
      2. For WeChat and QQ, contact your Account Manager.
    2. Set up the asset for your Unity project.
    3. Implement authentication logic on the application side.

    • Android class name — the class name of the main activity, including the namespace of the application (e.g., com.domain.appname.activity). The class name can be found in AndroidManifest.xml. The main activity’s tag should contain an intent-filter tag with the android.intent.action.MAIN action and the android.intent.category.LAUNCHER category.
    • Android hash key. You can get it with OpenSSL.
