Xsolla SDK for Unity - Mobile

ℹ️U.S. rules for iOS and Android — external payment link-outs and alternative billing solutions

iOS — Effective Apr 30, 2025: Developers may include external payment links in U.S. apps. The Xsolla SDK aligns with Apple’s updated guidelines.

Android — Effective Oct 29, 2025: Following the Epic v. Google injunction, U.S. Google Play apps may guide users to external payment methods via link-outs, use alternative billing solutions, and are no longer subject to anti-steering restrictions.

For both platforms, the fastest recommended non-SDK approach is the Buy Button via link-outs to Web Shop ↗ (https://developers.xsolla.com/solutions/web-shop/other/instant-purchase).
