Add registrant to a webinar



We need implement in our website a button to allow the logged users to register into a webinar

I have made a test page implementing the javascript code provided in api-reference/zoom-api/webinars/webinarregistrantcreate

But I get this warning message in the console (firefox): Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

We cannot change anything in our server and we cannot use server calls to zoom api, we have to use javascript code jquery (client side)

Please, could you tell me if is possible implement this functionality and what are the steps that we have to do?

Many thanks in advance


Hello @araceli_2,

Unfortunately right now, the only way to add a registrant on the web is through our REST API.

Hello Michael

Many thanks for your reply

As we have a very restricted server rules, we cannot use server calls…

It is possible to send by querystring the form parameters to the registration web address of a webminar?

For example: send name, surname, email, etc by querystring like this in order to avoid the user to enter his data manually?

Thanks and regards



Hi @araceli_2,

Currently, we don’t allow sending in data to add registrants using the web address for security concerns. The only ways are through the web portal, API, or SDK.
