I am encountering an issue while adding participants via the Zoom API. For most participants, I am receiving the following response: { "registrants": [] } - Status 201 However, a few participants are being successfully registered, received 200 response

We’re encountering an issue when creating meetings through the Zoom API. We are currently facing some technical issues with zoom integration, where some of the users do not get any response in a random manner, the API returns a 201 empty response, However, a few participants are being successfully registered, and I receive a proper success response for them with status 200. Could you please help identify the reason for this behavior and provide a resolution?

Hi @Test3
Thanks for reaching out to us and welcome to the Zoom Developer Forum. I am happy to look into this
Would you be able to help a request URL sample and a request body you are sending when getting these 201 codes.
If you could also grab the tracking ID in the response headers, that will make it easier for me to troubleshoot

Sure Elisa. I attached details below. Kindly do the needful.

URL:
baseurl/{meetingid}/batch_registrants

Sample JSON input Payload:
{
“auto_approve”: true,
“registrants_confirmation_email”: true,
“registrants”: [
{
“email”: “janarth.ramasamy@gmail.com”,
“first_name”: “Jana”,
“last_name”: “R”
}
]
}

Hi @Test3
Thanks for sharing more details with me.
It looks like your request URL is incomplete.
Make sure to follow this format:
