Participant Metrics

The GetCallParticipantSessionMetrics endpoint returns detailed media quality metrics for a single participant session, including published track statistics such as bitrate, framerate, and resolution over time. To discover available sessions and their user_session_id values, use the Call Attendance endpoint.

Response overview

user_id: ID of the user.
user_session_id: ID of the user's session.
publisher_type: Type of publisher (webrtc, rtmp, srt, etc.).
joined_at: Timestamp when the participant joined.
is_publisher: Whether the participant published media.
is_subscriber: Whether the participant subscribed to media.
client: Information about the participant's client:
- name: Client name (e.g. browser or SDK name).
- version: Client version.
- ip: IP address.
- network_type: Network type (e.g. wifi, cellular).
- location: Geographic location derived from the IP address:
  - city, subdivision, country, country_iso_code, continent
  - latitude, longitude, accuracy_radius_meters
published_tracks: Array of published track metrics. Each entry contains:
- track_id: Track identifier.
- track_type: Track type (audio, video, screensharing, etc.).
- codec: Codec used.
- bitrate: Bitrate time series — data_points is an array of [timestamp, value] pairs.
- framerate: Framerate time series (video tracks only).
- resolution: Resolution time series — width and height each contain a data_points array.
- warnings: Array of quality warnings:
  - time: Timestamp of the warning.
  - code: Warning code.
  - warning: Human-readable description.

Time range

Use since and until to narrow the metrics to a specific time window within the session. By default, the last 1 minute of the session is returned. The maximum window is 30 minutes.

const response = await call.getCallParticipantSessionMetrics({
  session: "<session-id>",
  user: "<user-id>",
  user_session: "<user-session-id>",
  since: new Date("2024-01-01T00:00:00Z"),
  until: new Date("2024-01-01T01:00:00Z"),
});
