MS Teams Live - adding attendees

Question

Hi,

Are there API interfaces to control MS Teams Live events? We would like to create a bespoke event registration page (kind of a middle-man), that would then automatically register user for MS Teams Live event. There's a lot of extra info we would like to collect, some of it from a dropdown with pre-set options.

Has anyone ever done anything like this? Are there any examples using Microsoft Graph API?

Thanks in advance

Don't know why I didn't try reverse engineering the MS Teams Live event registration page in the first place. You can manually register attendees for a MS Team live events. You need to get a skypeToken first:

• Make POST request to https://authsvc.teams.microsoft.com/v1.0/authz/visitor with your tenantId in POST body:

{"tenantId": "<tenant_id>"}

• Make POST request to https://teams.microsoft.com/api/webinar/prod/beta/webinar/<event_id>/attendee

Set x-skypetoken header to skypeToken returned from first request Include all required information in POST body:

{"Questions": [ {"InternalName":"PredefinedQuestionFirstName","Value":"foo"} ... ], "TimezoneOffset":0,"LocalizedTimezone":"(UTC+00:00) Dublin, Edinburgh, Lisbon, London","Language":"en-us","TimeZoneDetails":{"TimeZone":"GMT Standard Time","UtcOffset":0}}

If you're not sure what the POST for second request should look like, you can always register for event in browser, with Developers Console open, and check value of POST body in request.
