Hi, @balavishnu,  
Thank you for posting in the Developer Forum. It looks like the start\_time field is missing the seconds. Can you try to update the webinars with the start time formatted like so: start\_time": “2021-05-15T10:00:00Z”

For reference, I’ve included a Patch request below :  
{  
“topic”: "Updated The Webinar Date : ",  
“start\_time”: “2021-05-15T10:00:00Z”,  
“duration”: “30”,  
“agenda”: “Updated Agenda”  
}

Please give that a try and let us know if that resolves the problem.

Best,  
Donte

Hi @balavishnu,

The expected response for the [Update Webinar](https://marketplace.zoom.us/docs/api-reference/zoom-api/webinars/webinarupdate) endpoint is 204 on success:  
 ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/f/3/f3fb4f0daa01a7cb93f7961b44bd5ddb358d4b5e.png)

You should not expect a payload in response, but note that the webinar will have been successfully updated if you receive a 204.

Let us know if you have further questions about this.

Thanks!  
Will
