I got an following error while I am executing webinar registration API.

**API URL:** [https://api.zoom.us/v2/webinars/{webinarId}/registrants](https://api.zoom.us/v2/webinars/%7BwebinarId%7D/registrants)

**Response**  
Client error: `POST https://api.zoom.us/v2/webinars/675293803/registrants` resulted in a `404 Not Found` response:  
{“code”:1001,“message”:“The email address has not been used as a Zoom account”}

I wonder more about this, but never got why I got this response.

Hi @mukund.topiwala ,

Since troubleshooting this issue would require requesting private credentials from us, can you please send a support ticket at [developersupport@zoom.us](mailto:developersupport@zoom.us) ?

Thanks!

Are registrants required to have an existing Zoom account?

I actually noticed this when reviewing the webinar api documentation and came to the forum to see if other developers ran into this issue - - this implies the user must already have a zoom account to join a webinar - - or does the registration process create a Zoom account?

If registration is required for the Webinar, yes, they will need to have a Zoom account.
