# Add a webinar registrant

Registers a person for a webinar and returns their registrant ID and personal join URL.

`email` and `first_name` are required. 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: `POST /webinars/{webinarId}/registrants`
- 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.
