Steps
Identify the webinarKey and, for recurring/series webinars, the specific sessionKey you want attendance for.
Call the session attendees endpoint (scoped under organizers/{organizerKey}/webinars/{webinarKey}/sessions/{sessionKey}/attendees) for per-attendee join/leave times and total duration.
Cross-reference attendee records against the registrant list to compute registered-vs-attended rates.
Archive attendance data you need to retain long-term, since GoTo's session history retention window is limited.
Fall back to the Attendee Report CSV export in the dashboard for fields not exposed by the API.
Known gotchas
Attendance is reported per session, not per webinar series — a recurring webinar with 10 occurrences needs 10 separate attendee-report calls.
Historical attendance/session data has a retention limit (historically documented around 12 months); don't assume it's queryable indefinitely.
