Steam browser protocol
There are numerous system-wide commands available that interact with Steam. All of them open up Steam if it is not open. They can either be typed into a command box (Start-> Run) or through your browser's address bar (you can normally create links to them as you would web page links). Use a Steam Application ID in place of <id> (i.e. 211 for the Source SDK).
steam:<commands>This opens Steam with command line arguments, which can be found here: Steam Command Line OptionsNote: If you forget the closing quote on a steam:"<command>", you will get an assertion failed error from Steam.exe/BootStrapperApp.cpp.
steam://advertise/<id>This opens up the store for an app.
steam://appnews/<id>This opens up the appnews web page for an app.
steam://backup/<id>This opens up Steam's backup utility. If an AppId is specified then the product is checkmarked automatically.
steam://connect/<IP or DNS name>[:port]This connects the user to the server specified by the IP or DNS name. Using this, you can connect to servers for third party mods without needing to know the mod's installation path.
steam://defrag/<id>This defragments the GCFs associated with an installed application.
steam://install/<id>This installs an app.
steam://installaddon/<addon>This installs the specified add-on. Example: Template:Steamlink installs HL High-Def Pack
steam://open/<component>Opens a Steam window. Known <component> values:
steam://openurl/<url>Opens URL in default web browser.
Cancels an ongoing PayPal transaction.
steam://preload/<id>This preloads an app.
steam://publisher/<name>Loads the specified publisher catalogue in the Store. Type the publisher's name in lowercase, e.g.
steam://purchase/<id>This opens a dialog box to buy an app from Steam.
steam://purchase/subscription/<id>This opens up a dialog box to buy a subscription to a Steam product/service. None are available yet.
steam://removeaddon/<addon>This uninstalls the specified add-on. Example: Template:Steamlink uninstalls HL High-Def Pack
steam://run/<id>This opens an app.
steam://runsafe/<id>This resets CVARs of an app.
steam://open/settings, but also allows for subcommands for each page:
steam://store/<id>This opens up the store for an app, if no app is specified then the default one is opened.
steam://support/<params>Launches the Steam Support utility, running all tests. Enter [[Steam:// Support Strings|valid support string]] to filter results.
steam://updatenews/<id>This opens the news about the latest updates for an app.
steam://validate/<id>This validates the GCFs of an app.
The following commands are community suggestions and are not presently featured in Steam:
steam://connect/<IP or DNS name>[:port]/<password>
- Connects to the specified server with the right password --Semi
steam://connect/<IP or DNS name>[:port]/'command1 "arg1" "arg2";command2 "arg1";password "blah";etc..'
- Connects to the specified server after executing the specified commands --ts2do
- Open title page on the VDC. -- AiusEpsi and ts2do
steam://gameinfo/<IP or DNS name>[:port]
- Opens the "Game Info" dialog for the specified server. Maybe also integrated into the server browser, so you don't have to add a server to the favorites to have access to that window. --Koraktor
- Runs an app, then shuts down Steam once the game closes. -- AiusEpsi
- Forces update (if autoupdate fails) of all files (including all linked .gcf) for defined AppID. -- Dwarden
- Restarting Steam would be simpler, and have the same effect. --TomEdwards 08:23, 13 Sep 2006 (PDT)
- i'm afraid it's not that simple, see my post there http://forums.steampowered.com/forums/showthread.php?s=&threadid=485982 -- Dwarden
- Compares actual local build of AppID with latest version available at Steam servers for defined AppID.
- Results displayed in way: '<AppID> - <ActualLocalBuild>:<LatestBuildAtSteamServers>
- and if they not match it offers user dialog to force update to latest build.
