Using Steam Workshop Collections Print

In this guide, I’ll show you how to install and manage Steam Workshop Collections for your Garry’s Mod server using the FinnishHost Game Panel. Workshop collections make it easy to manage multiple addons with one ID and keep them automatically updated.

Step 1: Create or Find a Workshop Collection

Go to the Garry’s Mod Workshop on Steam.

Either create your own collection or use an existing one. Copy the numeric ID from the collection’s URL. Example:

https://steamcommunity.com/sharedfiles/filedetails/?id=123456789

In this case, the Workshop Collection ID is 123456789.

Step 2: Add the Collection to Startup Parameters

1. Open your FinnishHost Game Panel.
2. Go to Commandline / Startup Parameters.
3. Add or edit the following line:

+host_workshop_collection 123456789 +authkey YOUR_STEAM_API_KEY

Replace 123456789 with your collection ID, and YOUR_STEAM_API_KEY with your key from https://steamcommunity.com/dev/apikey.

Step 3: Save and Restart

Click Save, then Start your server. During startup, your server will automatically download and mount all Workshop content listed in the collection.

Step 4: Verify Workshop Downloads

Open the Web Console during startup and look for lines such as:

Downloading Workshop Addon: 123456789 (Addon Name)

If you see “HTTP Error” or “Failed to download addon,” double-check your API key or verify the collection’s visibility is set to “Public.”

Step 5: Keep Addons Updated

Steam Workshop content updates automatically when your server restarts. If an addon update causes problems, temporarily remove its ID from the collection and restart your server.

Step 6: Common Issues

• Collection not loading: Ensure the Workshop collection is public on Steam.
• Invalid API key: Your Steam key must belong to the account that owns or subscribes to the collection.
• Addon dependency errors: Some addons require specific base packs (e.g., @DarkRP, @TTT base).
• Missing textures: Install missing Source content such as Counter-Strike: Source (see our “Missing Content” guide).

Notes

We provide support for Workshop configuration, hosting, and startup only. We don’t provide support for broken addons, scripting conflicts, or third-party content errors. Always make backups of your Workshop collection IDs before making major changes.
