Steps
Ensure the webinar's approval_type is set to require registration — registration endpoints behave differently for auto-approve vs. manual-approval webinars.
POST to https://api.zoom.us/v2/webinars/{webinarId}/registrants with first_name, last_name, and email as the minimum required fields.
Read registrant_id and join_url from the 201 response and deliver it to the registrant.
For manual-approval webinars, call PUT /webinars/{webinarId}/registrants/status with action set to approve, cancel, or deny to move registrants between states.
List registrants with GET /webinars/{webinarId}/registrants, filtering by status (pending/approved/denied), since a single call doesn't return all statuses at once.
Known gotchas
webinar:write scope plus a Pro-or-higher plan with the Webinar add-on are both required — missing either produces an auth-looking error that's actually a plan/scope issue.
Once a registrant is approved or denied/canceled, there is no API action to revert them back to "pending".
