Microsoft Teams supports multiple types of scheduled real-time voice and video experiences. These range from ad hoc meetings suitable for a small number of participants to large structured virtual events like webinars and town halls that include thousands of attendees.   

The following table provides a comparison of the types of meetings that Teams supports. 

 To learn more about the differences between each meeting type to help you choose the one that is best suited for your use case, see the feature comparison chart.  

Microsoft Graph APIs for online meetings are already generally available. Developers can use these APIs to programmatically schedule online meetings with the appropriate meeting options. Today, we’re announcing the general availability of new Teams webinar APIs. 

What’s new?  

The following resources are now generally available: 

• virtualEventWebinar  – Used to create, get, update, publish, cancel, and list Teams webinars.  

• virtualEventRegistration – Used to create, get, cancel, and list registration records of registrants of a webinar. Provides the unique Teams webinar join URL for the registered registrant.  

• virtualEventRegistrationQuestion – Used to create, list, and delete either custom registration questions or predefined registration questions for registrants to answer when they register for a webinar.  

• virtualEventWebinarRegistrationConfiguration – Contains information about a webinar registration configuration that stores the registration portal URL of the webinar.  

• virtualEventPresenter – Used to create, get, list, update and delete a presenter for a Teams webinar. 

• virtualEventSession – A webinar created via Microsoft Graph APIs only has one session that inherits the properties of online meetings. 

• meetingAttendanceReport – Each time a webinar ends, an attendance report is generated for the session but doesn’t include attendee data.   

• attendanceRecord – Provides webinar attendee data in the attendance report.  

• Virtual event webhooks – Can receive notifications for changes to a webinar, webinar registration, session, attendance report, and so on.  

Webinar personas 

To make the best use of the Teams webinar APIs, it’s helpful to understand the personas for the users who access the Teams webinar experience:  

• Organizers are employees (in your organization) who manage the webinar. They are the authority on schedule and participants. They configure webinar attributes such as title, theme, attendee experience, and email rules.   

• Presenters are employees (in your organization) or external participants who lead the webinar.   

• Registrants are users (in or outside of your organization) who have registered for a webinar. They can be registered, waitlisted, or rejected. They can choose to cancel their webinar registration.   

• Attendees are registrants who join the webinar. They need to have registered through a portal and answered registration questions. 

• Teams tenant administrator must authorize custom applications with appropriate permissions.
