Example 3: Invite participants to an existing group call, replacing an existing Peer-to-Peer call

The invite API supports only one participant when replacing an existing peer-to-peer call. When multiple participants are provided in the request body, only the first participant will be read and the rest of the participants will be ignored.

Note: The invite API supports only one participant when replacesCallId is provided. For details about using replacesCallId to replace an existing peer-to-peer call, see invitationParticipantInfo.

Note: With a completed status, you can expect to receive notifications about how your original peer-to-peer call has been terminated and deleted.

Example 5: Move one participant from one meeting to another

You can move one participant from one meeting to another if these two meetings have been created by the same application. For more information about how to create an online meeting, see Create onlineMeeting.

Note: The invite API can move only one participate per request. If you provide more than one participant in the request body, the invite API will move only the first one.
