}How to Find an Arma Reforger Mod ID
Every Workshop mod has a 16-character hexadecimal GUID that uniquely identifies it. To find a mod's ID, open the mod's page on the Arma Reforger Workshop and look at the URL. For example:
https://reforger.armaplatform.com/workshop/59B657D731E2A11D-Overthrow
The part between /workshop/ and the dash is the mod ID: 59B657D731E2A11D. Paste either the full URL or just the 16-character GUID into the input above — this tool will extract the GUID automatically.
Or just use the search box in this tool — it queries Bohemia's Workshop database directly via the XGamingServer mod API. Paste a URL, GUID, or type a name and the tool fills in name, version and size for you.
Mod JSON Format
Arma Reforger servers load mods via the mods array in config.json. Each entry is an object:
"mods": [
{
"modId": "59727DAE364DEADB",
"name": "ACE Reforger",
"version": "1.2.3",
"required": true
}
]- modId — Required. The 16-character hex GUID from the Workshop URL.
- name — Optional. Human-readable label for logs and admin UIs. Not used for matching.
- version — Optional. Pin a specific version. Omit to always use the latest.
- required — Optional. If
false, the server skips this mod if it can't be downloaded instead of refusing to start.
Required vs Optional Mods
The per-mod required field and the top-level modsRequiredByDefault option control what happens when a mod is missing or fails to download:
- Required (default) — the server will refuse to start until every required mod is present and valid.
- required: false — the server logs a warning and keeps starting without the mod. Clients who do have it will still load it; clients who don't will play without it.
- modsRequiredByDefault: false — flips the default for every entry, so only mods with
required: trueare mandatory. Useful for heavily modded sandboxes where individual cosmetic packs are optional.
Mod Dependencies and Load Order
Reforger loads mods top-to-bottom from the mods array. Dependencies must appear before the mods that rely on them. The most common example is Overthrow: faction packs and enhancements extend the base Overthrow framework, so the base 59B657D731E2A11D entry must be listed first. This tool will flag that situation automatically.
When in doubt, check the mod's Workshop description — authors almost always list required dependencies there.
Why PS5 Players Can't Use Mods
Sony does not allow user-generated Workshop content on the PlayStation Store. When your server's supportedPlatforms list includes PSN, PS5 clients silently ignore every entry in the mods array. Xbox and PC players on the same server will still get the mods.
If your server is mod-heavy and you want a consistent experience, remove PSN from supportedPlatforms so PS5 players can see at a glance that the server won't work for them.
FAQ
How do I find the mod ID for an Arma Reforger mod?
Open the mod on reforger.armaplatform.com/workshop and copy the 16-character hex string from the URL, right after /workshop/. It looks like 59B657D731E2A11D. You can also paste the full URL into this tool — it extracts the GUID automatically and resolves the mod's name, version and size from the Workshop API.
Should I include a version number?
Usually no. Leave version empty so the server always uses the latest build. Only pin a version if you need to freeze the modpack for a scheduled event or if a newer release broke compatibility.
What does required: false do?
It tells the server to skip the mod (and keep starting) if the download fails or the mod has been removed from the Workshop. Clients that have the mod still load it. Use this for optional cosmetic packs.
Why won't my server start after adding mods?
Usually a typo in the GUID (Reforger IDs are strict 16-char hex), a missing dependency (Overthrow add-ons without the base Overthrow mod), or a mod that was delisted. Check the server log — it names the offender. You can also set required: false on suspect mods to isolate the problem.
What order should I list mods?
Dependencies first, add-ons second. For Overthrow servers: base Overthrow at the top, then faction/map packs. For ACE-based servers: ACE core first, then ACE extensions, then gameplay mods that read ACE settings.
Can console players use mods?
Xbox players can. PS5 players cannot — Sony policy forbids Workshop content on PlayStation. If PSN is in your supportedPlatforms, mods are silently ignored on PS5 clients only.
What is modsRequiredByDefault?
A top-level config.json flag that sets the default for every mod entry without an explicit required field. Set it to false if most of your pack is optional cosmetics, then opt-in individual core mods with required: true.
