General information

The payment UI is based on the Pay Station product. The choice of available payment methods and other settings are available in Publisher Account in the Pay Station section.

The SDK supports the item purchase from the catalog in one click or via the shopping cart.

To test the purchase process, you can use sandbox mode of payment UI and test cards. The sandbox mode only simulates the behavior of a payment method; no real money is involved. To try sandbox, you don't need to sign any agreements with Xsolla or pay any fees.

After the first real payment is made, a strict sandbox payment policy takes effect. Payments made in sandbox mode are available only to users who are specified in Publisher Account in the Company settings > Users section.

How to set up payments via Steam

Xsolla can act as a payment gateway when players pay for in-game purchases via Steam. In this case, you don’t need to integrate the Steam SDK or take into account the nuances of paying via Steam when setting up an in-game store.

To set up payments via Steam:

  1. Sign an additional agreement with Xsolla.

Xsolla takes a reduced Revenue share when making payments via Steam. Check the details with your Account Manager.

  1. Set up the gateway for Steam in your Publisher Account.
  2. Set up native authentication via Steam.
  3. Go to your Unreal Engine project.
  4. Go to Settings > Project Settings > Plugins > Xsolla Settings and check the Build for Steam box.

After changing the Unreal Engine project settings, the x-steam-userid header will be added to the payment token request.
