Hey Developers, this is Xsolla's SDK 3.
Hello Developers! We are Xsolla's Developer Relations Team and in this blog we want to tell you about Xsolla's SDK 3, the latest rev of our software toolkit that enables you to add monetization to your mobile and PC games all with one simple integration that takes less than 15 minutes to implement.
Previous versions of Xsolla's SDK duplicated the same logic across every integration target. SDK 3 moves that logic into a single native core and reduces each integration to a thin wrapper over it — one implementation, many bindings. Checkout follows the same principle: instead of shipping our own embedded browser, SDK 3 renders through the surfaces the operating system already provides, and treats link-out as a first-class flow rather than a fallback.
With SDK 3, you can add monetization to your games and start selling powerups, skins, equipment and whatever else suits your game design with four simple steps: Authenticate, Load Catalog, Initiate Purchase, and Finalize Transaction.
Integration Guides
To get you started, we have created a selection of materials covering several different platforms and engines that will walk you through the integration.

Platform Compliance
iOS: Following the April 30, 2025 U.S. court decision, developers may include external payment links in iOS apps. The Xsolla SDK for Mobile is fully compliant with Apple's revised App Store guidelines, supporting both in-app Pay Station flows and link-out payments via Web Shop.
Android: Following the October 29, 2025 Epic v. Google injunction, U.S. Google Play apps may use alternative billing solutions, external payment links, and are no longer subject to anti-steering restrictions. The SDK supports out-of-store APK distribution, Google Play Billing, and browser-based checkout - all in one integration.
