Memberships represent a person's relationship to a room. Use this API to list members of any room that you're in or create memberships to invite someone to a room. Compliance Officers can now also list memberships for personEmails where the CO is not part of the room. Memberships can also be updated to make someone a moderator or deleted, to remove someone from the room.
Just like in the Webex client, you must be a member of the room in order to list its memberships or invite people.
