I am trying to have a form hosted on my website where the user can sign up for multiple webinars at a time and then once the user submits the form we use the ZOOM API to create/sign up the user for the webinars selected. I was trying to find something like this on the forums but wasn’t having any luck with it.
**Which App Type (OAuth / Chatbot / JWT / Webhook)?**
Currently have JWT but not sure if this is the right APP Type for what I want to be done.
Any help would be greatly appreciated.

Hey @DevCoder,
Thank you for reaching out to the Zoom Developer Forum. You can use the [Add a Webinar Registrant API](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantcreate) in order to sign users up for a webinar programmatically.
Let me know if that helps. 🙂
Thanks,
Max

Thanks for the reply @MaxM
I been trying to get this API post to work on postman to test and I am getting stuck on a error;
```
300
Unsupported Content Type
```
If i take off the content type still get the same result. Any help on moving forward would be greatly appreciated.

I was able to solve the problem, but i had to send the information of the body raw, if I wanted to use form data instead do you know what I would need to do to achieve this? I currenly have the content-type to be application/json, not sure if that would need to get changed.
Thanks!

Hi @DevCoder ,
You’ve found the right solution. Currently our API only supports a **contain type** of application/ json. We’ve reached out to our documentation team to have this corrected. Thank you for bring this to our attention.
Best,
Donte
