Get started

Integrating with Xsolla servers is suitable for partners who want a ready-made server solution for monetization and in-game items management.

After integration of Xsolla SDKs, you can use:

With this integration, all operations are processed on the Xsolla side and you do not have to configure your own server side for these tasks.

Choose and install one of the following assets depending on your needs:

  • Store Unity SDK — contains all the necessary methods to integrate all Xsolla products listed above.
  • Login Unity SDK — designed to implement only the functions of the Xsolla Login.
  • Inventory Unity SDK — designed to implement functions of the Xsolla Login and the Player Inventory. Use this asset if your application is published on a platform that cannot use the Xsolla Pay Station and In-Game Store for some reason.

All assets are not compatible with each other. Choose and integrate only one asset that best suits your needs.
