**Description**  
I am trying to register users for a Webinar using API. I am able to successfully register the user.  
I want to add custom questions in the registration process as well.  
I want to to have multiple “Required” custom questions".

I started with adding 1 custom question, made it “Required” and it worked.  
As soon as I try to make 2nd question “Required” my API fails.

**Error**

{  
“code”: 300,  
“message”: “The parameter is required in custom\_questions: Ques2 to answer?.”  
}

**Which App Type (OAuth / Chatbot / JWT / Webhook)?**  
OAuth

**Which Endpoint/s?**

**How To Reproduce (If applicable)**

Hi @mohit.punj,

Can you please ensure that you’re using this endpoint to update custom questions for your registration?

> **[Update Registration Questions - Webinars - Zoom API - API Reference](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarregistrantquestionupdate)**
>
> Scheduling a Webinar with registration requires your registrants to complete a brief form with fields and questions before they can receive the link to ...

The endpoint you’re referencing is intended for adding a webinar registrant, not updating the webinar’s custom questions.

Let me know if this helps!  
Will
