Attendee - Amazon Chime SDK
ContentsSee Also

Attendee

An Amazon Chime SDK meeting attendee. Includes a unique AttendeeId and JoinToken. The JoinToken allows a client to authenticate and join as the specified attendee. The JoinToken expires when the meeting ends, or when DeleteAttendee is called. After that, the attendee is unable to join the meeting.

We recommend securely transferring each JoinToken from your server application to the client so that no other client has access to the token except for the one authorized to represent the attendee.

AttendeeId

The Amazon Chime SDK attendee ID.

Type: String

Pattern: [a-fA-F0-9]{8}(?:-[a-fA-F0-9]{4}){3}-[a-fA-F0-9]{12}

Required: No

Capabilities

The capabilities assigned to an attendee: audio, video, or content.

Note

You use the capabilities with a set of values that control what the capabilities can do, such as SendReceive data. For more information about those values, see AttendeeCapabilities.

When using capabilities, be aware of these corner cases:

  • If you specify MeetingFeatures:Video:MaxResolution:None when you create a meeting, all API requests that include SendReceive, Send, or Receive for AttendeeCapabilities:Video will be rejected with ValidationError 400.

  • If you specify MeetingFeatures:Content:MaxResolution:None when you create a meeting, all API requests that include SendReceive, Send, or Receive for AttendeeCapabilities:Content will be rejected with ValidationError 400.

  • You can't set content capabilities to SendReceive or Receive unless you also set video capabilities to SendReceive or Receive. If you don't set the video capability to receive, the response will contain an HTTP 400 Bad Request status code. However, you can set your video capability to receive and you set your content capability to not receive.

  • If meeting features is defined as Video:MaxResolution:None but Content:MaxResolution is defined as something other than None and attendee capabilities are not defined in the API request, then the default attendee video capability is set to Receive and attendee content capability is set to SendReceive. This is because content SendReceive requires video to be at least Receive.

  • When you change an audio capability from None or Receive to Send or SendReceive , and if the attendee left their microphone unmuted, audio will flow from the attendee to the other meeting participants.

  • When you change a video or content capability from None or Receive to Send or SendReceive , and if the attendee turned on their video or content streams, remote attendees can receive those streams, but only after media renegotiation between the client and the Amazon Chime back-end server.
