Find an Arma Reforger mod ID (GUID) for your server

A Reforger mod ID is a 16-character code. Read it from the ID line on the mod's Workshop page or the ArthOS Mods page, then use it in config.json.

Updated , checked on Arma Reforger 1.8.0.13

A mod ID, also called a GUID, is the 16-character code that identifies one Workshop mod, for example 5AAF6D5352E5FCAB. It is listed as ID on the mod’s page on the Arma Reforger Workshop, and the same code is the last part of the page’s address.

On the Workshop

  1. Open https://reforger.armaplatform.com/workshop and find the mod.
  2. Open its page. Below the description is a block of details: Version, Game Version, Version size, Subscribers, Downloads, Created, Last Modified and ID.
  3. Copy the value next to ID. It uses the digits 0 to 9 and the letters A to F.

For example, the page for Project Redline - Core at https://reforger.armaplatform.com/workshop/5AAF6D5352E5FCAB lists the ID 5AAF6D5352E5FCAB.

Bohemia’s server documentation names two other places for mod authors: the Workbench options while a mod is running, and the mod’s .gproj file.

In the ArthOS panel

Open your server, choose Mods, then the On this server tab. Every row shows the mod’s ID (1) in small type under its name, next to its size, the game version it was built for and whether it is installed.

On this server list: each mod with its load order number, picture, name, ID and size
  1. Mod ID line
  2. Search by name or ID

To find one mod in a long list, type part of its name or ID into the search box (2).

The Workshop tab does not show IDs. It searches by name, and each card has an external link, Open on the Workshop, that goes to the mod’s Workshop page where the ID is printed.

Use the ID

Put it in the modId key of an entry in game.mods in config.json:

{ "modId": "5AAF6D5352E5FCAB", "name": "Project Redline - Core" }

The name key does nothing; it is only a note for you. Full steps are in how to install Arma Reforger mods.

Bohemia’s startup parameter -addons, used when starting the game yourself, takes the same GUIDs, comma separated.

If it does not work

  • The server will not start and the log names an ID. The ID is wrong or the mod was removed from the Workshop. Check it against the Workshop page, or follow find the mod that stops your server.
  • You have a name but no ID. Open the mod’s Workshop page and read the ID line.
  • An ID from a forum post does not match any mod. Check you copied all 16 characters, with no spaces.
