Xsolla SDK for Windows

🚀 now available

The native Xsolla SDK for Windows is now available, bringing powerful monetization tools to any game published on the Microsoft platform and across Windows stores!

The Xsolla SDK for Windows brings out-of-store commerce, in-app purchases, and global payments to games on the Microsoft platform.

信息

If you are using Unity for your project, we recommend integrating the Xsolla SDK for Unity. For more details, please visit this page.

With a single integration, the SDK empowers developers to connect directly with players, maintain control over the checkout experience, and keep up to 95% of their revenue. It supports side-by-side in-store checkout where allowed, enabling flexible billing strategies and loyalty incentives. Games automatically benefit from updates for new monetization tools, regulatory compliance, and global policy changes.

With built-in IAP catalog sync, streamlined tax onboarding for flexible payouts, and support for more payment methods and local currencies, the Xsolla makes scaling Windows games across stores and regions simple. Developers can focus on building their game, while Xsolla handles the complexity of payments, payouts, and compliance.

Platform Support​

Epic Games Store & 3rd-Party Commerce​

Epic Game Store policy allows developers to use alternative payment methods, including browser-based flows, provided they handle processing and fulfillment. See Epic's official documentation for details.

That means developers can run their own payment system alongside—or instead of—the Store's commerce, giving full control over offers to players via features like dual billing, web shop purchases, and player incentives. Explore this article for more details.

Game Engine Coverage​

  • Unity: Use the Xsolla SDK for Unity for Windows games built with Unity.
  • Custom Engines: Native SDKs available in C++ and C# for full flexibility.
  • Defold: Integrate payments quickly with the Xsolla SDK for Defold, available on Defold Asset Portal.
  • More Coming Soon: Support for additional engines is in progress—stay tuned!
