I’m trying to send a request for get List Webinars here: [https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinars](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinars)

But i get:  
{  
“code”: 1001,  
“message”: “User not exist: 9105128131”  
}

Where i can get the right User ID?

Thanks!

Hi @sistemi,

Thank you for reaching out to the Zoom Developer Support Forum.

Please use the [List Users Api](https://marketplace.zoom.us/docs/api-reference/zoom-api/users/users) , to get the value for `userID` .

Once you get the `userID`, use it to retrieve your Webinars.

Please let me know if you have any questions.

Thanks

Hi @avv.lazzari when you use the List Users API, do you see the user you are looking for on your account?

What is the API endpoint you are requesting?

Are you using a JWT or OAuth app?
