We have opened a bug around a recent undocumented change in the Web Services API actions.
The action, sco-session-seminar-list, which prior to 9.2.2 returned all seminar sessions for which the authenticated user had Host permissions, now requires the alternative action: sco-seminar-sessions-list. Use sco-seminar-sessions-list instead of sco-session-seminar-list until we resolve the open issue around this change; we have logged bug number: Watson: 3772441.
Consider this sample action (wherein FQDN designates your fully qualified domain name) as an example: Instead of running the action: https://FQDN/api/xml?action=sco-session-seminar-list&sco-id=1369951914 to get all the seminar sessions under the seminar license with the sco-id of 1369951914 you ought to run this API instead: https://FQDN/api/xml?action=sco-seminar-sessions-list&sco-id=1369951914
To list all the sessions that are linked to a meeting room under one license, put a filter on the source-sco-id as in this example action: http://FQDN/api/xml?action=sco-seminar-sessions-list&sco-id=sco-id-of-the-seminar-license&filter-source-sco-id=sco-id-of-the-meeting-room
