High-level Code

Xsolla provides a solid and extensive API for advanced control. General basic knowledge of the game engine is a prerequisite. Easy start with:

  • classes and methods for API calls
  • easy-to-use callbacks
  • components to synchronize GameObjects and Remote Procedure Calls (RPCs)


The included demo showcases one possible example of how the included and distinct Xsolla products work together. Use it for reference only, or as an initial quick start version that you can expand and customize as needed.

  • Xsolla Login & Account System is already included as part of Xsolla Game Commerce (XGC). You can download the XGC plugin if you need a broader set of features, but do NOT install these plugins separately.
