Create a virtual classroom via Adobe Connect 9 Web Services

The answer of Jorma Jenning is almost correct. I investigated it myself and finally made a working solution.

The trick is that virtual classroom does not have a special type, instead it is a "meeting inside trainings folder with the icon of virtual-classroom". Kinda strange logic and to add another level of hell the "trainings folder" is the one with the type "my-courses", so, finally, we get the the following workflow:

1. Call h-ttps://example.com/api/xml?action=sco-shortcuts and filter sco-s until you find one with the type="my-courses" and remember its sco-id — this will be your folder-id.

2. call  h-ttps://example.com/api/xml?action=sco-update&type=meeting&icon=virtual-classroom&name=October All Hands Meeting

          &folder-id=2006258750&date-begin=2006-10-01T09:00

          &date-end=2006-10-01T17:00&url-path=october

The thing with icon is important.

Note that if you call report-my-training service immediately after sco-update you won't see this virtual-classroom. This is because the default permissions do not allow that. Add yourself to the user list via permissions-update and it will appear in your training list. This is different from creating virtual classroom from web interface as there you are added as a host by default.
