With the deprecation of XML API there remains no tool to programmatically push the user to logged-in status on a Meetings site.
Currently we are using the "GetloginTicket" XML API (returning a "ticket") and the "AT=LI&TK={ticket}" URL API, and this method works fine, but the XML API will go away, and the URL API does not accept OAuth access token. I see two possible solutions:
1. The URL API accepts the OAuth access token. Please see my FR at https://ciscocollabcustomer.ideas.aha.io/ideas/WXCUST-I-7075
2. The CH managed Meetings site accepts the SAML 2.0 Assertion in IdP initiated scenario. This FR is about to ask for this feature.
