Pre-fill Webinar Registration Forms

This is more of an inquiry than an error, but I’m wondering if it’s possible to have webinar registration forms pre-filled with user data when navigating to the registration form page Is this possible through the use of url parameters?

I found this endpoint (, but using that assumes a webinar registrant has a Zoom account, which is not actually a requirement when registering for Zoom webinars.

Any help with this would be greatly appreciated, as we’re hoping to add this functionality to our product ASAP.

Thanks in advance,

Hey @andrew1, thanks for posting and using Zoom!

As of now we do not have a way to pre-fill webinar registration forms via query params.

Although, the POST /meetings/{meetingId}/registrants does not require the registrant to have a Zoom account, so you can customize or pre-fill this experience on your end.


Hi @tommy,

Thanks for the info. It looks as though that endpoint requires an oauth_access_token to be passed in. Won’t users have to go through the OAuth flow to get this token(meaning they’ll need to create or sign in to a zoom account)?

Thanks again

Hey @andrew1,

You can use your JWT token to make authenticated requests to register users without them having to OAuth into your application. As long as you own the meetingID :slight_smile:
