Workshop Browser

The Steam Workshop browser allows your users to download and install mods and maps from Steam with a single click.


Configure the Workshop Browser

Go to Settings > Default Steam Settings. Enter your Steam API key.

Go to Settings > Games > select the game > Steam Settings. Set the following values:

  • Store Id - Set the game's id in the Steam store. For example: https://store.steampowered.com/app/4000/Garrys_Mod/
  • Enable Workshop Browser - Enables the Workshop browser.
  • Stop before installing Workshop content - Specify if you want to stop the service before installing content.
  • Skip Workshop download - If enabled the content is not downloaded automatically. Use this option if the game can download content automatically.
  • Workshop file id format - Format used on the file id. For example if the file id needs @ at the beginning use @![FileId]
  • Workshop file id separator - Specify the characters used to separate file ids. Use ![NewLine] to separate with a new line character.

Go to Settings > Games > select the game > Feature Permissions and enable Workshop browser for users, resellers and sub admins. (If you want to test this feature as admin don't enable these options)

Sample Scripts

The Workshop browser downloads the content to ServiceRoot/steamapps/Workshop/content/STOREID/FILEID. It is up to the administrator to configure a script that moves the files to the correct location and update the config file. Contact TCAdmin support if you need help creating a script.
