Make sure you’re using the [panelist’s `/webinars/{webinarId}/panelists` endpoint](https://developers.zoom.us/docs/api/rest/reference/zoom-api/methods/#operation/webinarPanelistCreate), not the registrant’s [`/webinars/{webinarId}/registrants` endpoint](https://developers.zoom.us/docs/api/rest/reference/zoom-api/methods/#operation/webinarRegistrantCreate).
