Enterprise-level SDK for Unreal Engine / Overview

Enterprise-level SDK for Unreal Engine

Xsolla SDK for Unreal Engine is a ready-to-use library for applications/games that allows you to easily embed Xsolla services.

The SDK makes it easier to integrate Xsolla products into your Unreal Engine project by providing out-of-the-box data structures and methods for working with Xsolla API.

After integration, you can use:

  • Login to authenticate users and manage user accounts.
  • In-Game Store to manage in-game purchases in your application.
  • Pay Station to set up payments.
  • Subscriptions to provide users with access to a package of services under specified conditions (subscription cost and duration).




  • OAuth 2.0 protocol-based authentication.
  • Classic login via username/email and password.
  • Social login.
  • Social login on the user’s device via a social network client.
  • Login via a device ID.
  • Passwordless login via a one-time code or a link sent via SMS or email.
