Command line switch for GoToMeeting to join a meeting by ID?

Question

My colleagues and I have a recurring weekly meeting set up. I'd like to set up a shortcut to that meeting (in Windows 7). I can make a URL shortcut like this

https://www2.gotomeeting.com/join/123456789 

but that fires up a browser window which then has to be closed - it would be cleaner to just call g2mstart.exe with a command line argument to join meeting 123456789. I've tried guessing at the syntax to join a specific meeting but haven't found it, and haven't found a guide to command-line switches anywhere online. Clearly g2mstart.exe takes arguments - the standard shortcut looks like this:

"C:\Program Files (x86)\Citrix\GoToMeeting\457\g2mstart.exe" 
"/Action Host" "/Trigger Shortcut" "/Product G2M" 

Is there a guide somewhere to these switches? And is there one that allows joining a specific meeting by ID?

Answer 1

I found it after a little more trial and error:

"C:\Program Files (x86)\Citrix\GoToMeeting\457\g2mstart.exe" 
"/Action Join" "/MeetingID 123456789"

Answer 2

Similar to what Marco Valtas said you can simply create a shortcut on the desktop (or anywhere else) with the URI gotomeeting://SALaunch?Action=Join&MeetingID=123456789 this works great for me on Windows. No browser or anything, straight into the meeting.

Answer 3

It looks like in OSX the simplest way is to use the URL registred by GoToMeeting application on the LaunchServices which by using open you can pass the arguments. After some digging and trimming I could narrow down to this:

 open 'gotomeeting://SALaunch?Action=Join&MeetingID=123456789'

Answer 4

I guess you will still have to register (the same way as you would have if you used Join... from menu)

I tried and this works flawlessly: /UserID 123456789

Would love to find how this could've been done on a Macintosh
