When we edit “start time” of the webminar, this issue happens. Otherwise it works fine.
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 Donte,
Thanks, I tried that but still same problem. Below is the new request
{
"topic":"CHECK",
"start_time":"2021-05-20T18:00:00Z",
"duration":"1080",
"agenda":"CHECK"
}

Hi, @balavishnu,
Are you able to confirm if the Webinar information updated as expected ?
Thanks,
Donte
Yes, update working as expected. Just the response is not proper
Hi @balavishnu,
The expected response for the Update Webinar endpoint is 204 on success:

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
