[tommy (Tommy Gaessler)]

Hey @Ian_SITNB, @ecc, @conventionline,

I am not able to reproduce the issue:

POST https://api.zoom.us/v2/webinars/95197907800/registrants

{
  "email":"test1@gmail.com",
  "first_name": "TEST",
  "last_name": "TEST",
  "phone": "1111111"
}

Status 201

Response:

{
    "registrant_id": "gBQKCFcNSKOxVK6V9F9n1w",
    "id": ***********,
    "topic": "My Webinar",
    "start_time": "2020-07-23T17:00:00Z",
    "join_url": "https://tommygaessler.zoom.us/w/95197907800?tk=1HxYzeNtQrNUJqeHjvAza38AVlaCb4D888XXXXXXXX"
}

Can you please provide your request body JSON that is throwing the error, your Zoom account number, and your OAuth / JWT App Name?

Thanks,
Tommy
