1. Open your Unity project.
2. Click Window > Xsolla > Edit Settings in the main menu.

1. 1. In the Project ID field, specify the project ID that can be found in Publisher Account next to the name of your project.
   2. In the Login ID field, specify the ID of the Login project. To get it, open Publisher Account, go to the Login > Dashboard section, and click Copy ID next to the name of the Login project. If you use your own authorization system, leave the Login ID field empty.

The value must match the one specified in Publisher Account in the Login > your Login project > Callback URLs section.
