# List webinar participants

Returns the people who attended a past webinar, with name, email, join and leave times and seconds attended.

`duration` is in seconds per session: someone who leaves and rejoins appears again with a new entry, so add their durations up. `user_email` is empty for people outside the host's account, with some exceptions, so pass `include_fields=registrant_id` to match attendees to registrants. Needs a Pro or higher plan with the Webinar add-on.

## Set up

Use the first option your agent supports.

### API (official)

- Base URL: https://api.zoom.us/v2
- Endpoint: `GET /past_webinars/{webinarId}/participants`
- Auth: OAuth; sign in when the agent asks
- Docs: https://developers.zoom.us/docs/api/

Before doing anything else, make one read-only call to confirm access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data.
- Never print API keys.
