Every convoy setting is in one file, server_config.sii. It is written by the server the first time it starts, so start the server once before you look for it.
1. Open the file
- Stop the server in the Game Panel.
- Open the Files tab and find
server_config.sii. It sits next toserver_packages.siiin the server's data folder. - Click the file to open the editor.
2. The settings you will actually change
| Setting | What it does |
|---|---|
lobby_name | The name shown in the Convoy browser. |
description | One line under the name. |
welcome_message | Shown to a player as they join. |
password | Leave empty for an open session. |
max_players | Player slots. Convoy supports up to 8. |
player_damage | Whether trucks damage each other. |
traffic | AI traffic on or off. |
hide_in_company | Hides trucks inside company areas so they do not collide. |
friends_only | Restricts the session to your Steam friends. |
show_server | Whether the session is listed at all. |
server_logon_token | Your Steam game server token. Without it the session is not published. |
Values in quotation marks keep their quotation marks. Numbers and true or false do not take them.
3. Adding moderators
Moderators are listed by Steam64 ID at the end of the same file. The count line has to match the number of entries:
moderator_list: 1
moderator_list[0]: 76561198000000000
For two moderators the count becomes 2 and you add a moderator_list[1] line. A count that does not match the entries makes the file fail to load.
4. Getting a Steam game server token
- Go to the Steam game server account management page on your own Steam account.
- Create a token for App ID 270880, which is American Truck Simulator.
- Paste the token into
server_logon_tokeninserver_config.sii.
The token belongs to your Steam account and can be revoked by you at any time. Keep it private.
5. Save and restart
- Save the file.
- Start the server.
- Check the console for the session name and the Session Search ID.
Editing while the server is running does not work. The server rewrites the file when it shuts down.
