Currently the Windows Registry setting:
[HKEY_CLASSES_ROOT\zoomus\shell\open\command]
is updated with a Protocol definded as ‘zoom’
which redirects to
“C:\Users{username}\AppData\Roaming\Zoom\bin\Zoom.exe” “–url=%1”
Where is the document or please take a request to write a document that 
Describes the method of ‘deep linking’ via the protocol ‘zoomus://’ to provide a value of the ‘url%1’ parameter, and what are the valid values of the parameter?
the documentation of this “Deprecated Client URL Scheme”
https://developers.zoom.us/docs/client-url-schemes
is gone with the documentation upgrade this year
the page seems not to be archived on www.archive.org
this is what i have used
for desktop: zoommtg://zoom.us/join?confno=[meetingID]&pwd=[passcode]&zc=0&uname=[username]
for mobile: zoomus://zoom.us/join?confno=[meetingID]&pwd=[passcode]&zc=0&uname=[username]
I tried the zoommtg URI on windows and it worked just fine. Thank you!
So dissapointed that this knowledge is now ‘secret’ and there is no documentation on it.
Now I know Zoom refer to the windows protocol registration as “URL Schema” I found a few posts relating to other requests for more documentation:
Which Zoom Client URL Schemes parameters are required? - #6 by will.zoom responded to by @will.zoom I wonder whether the information provided was documented https://developers.zoom.us/docs
Who at Zoom Dev will release the documentation? @will.zoom ?
