Using the Config Editor
- In the XGamingServer Panel, click Arma Reforger Config
- Go to the Mods tab
Search & Add Mods

- Results show with thumbnails, names, and IDs
- Click Add — the mod is added to your config
- Dependencies are automatically resolved
Manual Add
If search doesn't find your mod:
- Enter the Mod ID (16-character hex from the Workshop page)
- Optionally enter a name
- Click Add Mod
Manage Mods
- Toggle Required on each mod to control whether clients must have it
- Click Remove to delete a mod from the config
- Use Import/Export to bulk manage mod lists as JSON
- Click Save Changes and restart your server
Via config.json
Add mods to the mods array inside the game block:
"mods": [
{
"modId": "597D72161FD1ED1D",
"name": "My Mod",
"version": "",
"required": true
}
]| Field | Description |
|---|---|
modId | 16-char hex ID from the Workshop page or mod's ServerData.json |
name | Human-readable label (cosmetic only) |
version | Pin to a specific version, or "" for always-latest |
required | If true, clients must have this mod to join |
Finding Mod IDs
- From the Steam Workshop URL: the hex string after the last
/ - From the mod's
ServerData.jsonfile - Via the Config Editor search (easiest)
Key Setting
In config.json:
"modsRequiredByDefault": trueWhen true, all mods in the list are required unless individually set to required: false.
