Get started

This integration option allows you to take advantage of Xsolla Pay Station if you use a third-party backend solution.

After integrating Xsolla SDKs, you can use Xsolla Pay Station for processing in-game purchases in combination with other BaaS providers responsible for game logic.

Currently, Xsolla provides integration with PlayFab services.
