# List webinar participants

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

Note: Someone who rejoins gets a new entry, so add up their durations. `user_email` is empty for people outside the host's account: pass `include_fields=registrant_id` to match registrants. Needs Pro or higher 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: an OAuth access token, sent as `Authorization: Bearer <token>`
- Docs: https://developers.zoom.us/docs/api/

Note: Get the access token from an OAuth app you create on the Zoom App Marketplace. Webinar calls need a Pro or higher plan with the Webinar add-on.

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
