Not able to register participants


We are registering users using Add a meeting registrant API, but we are getting

    "code": 1001,
    "message": "User does not exist:"

Meeting ID: 97188027858
Reason for the same?

@elisa.zoom Can you please check this?

Hey @sunstone.zoom
Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!
Could you please share the request URL and request body that you are sending so I can help debug this issue further?

Hi @elisa.zoom

Here’s the curl for your reference

curl --location --request POST '' \
--header 'Authorization: Bearer xxx' \
--header 'Content-Type: application/json' \
--data-raw '{
    "first_name": "Aparna",
    "last_name": "Pavani",
    "email": ""

Hey @sunstone.zoom

Thanks for sharing some more details with me.
It looks like the meeting that you are trying to add registrants to, does not exist.
Could you please confirm with me that you are calling this endpoint with an existing meeting?

Hi @elisa.zoom
It might have been deleted for some reason, here’s one more entry from my system logs

{"url": "", "json": {"email": "", "last_name": "Kairi", "first_name": "Vivek", "auto_approve": true}, "method": "POST", "headers": {"Content-Type": "application/json", "Authorization": "Bearer xxx"}}

with response

{"id": 96024388005, "topic": "Class for T4 - Introduction to Retail Management", "join_url": "", "start_time": "2022-08-04T13:30:00Z", "registrant_id": "bdEX0uReSBynwR-pTG1mEg"}

and same meeting for another user

{"url": "", "json": {"email": "", "last_name": "Sai", "first_name": "c", "auto_approve": true}, "method": "POST", "headers": {"Content-Type": "application/json", "Authorization": "Bearer xxx"}}

with response

{"code": 1001, "message": "User does not exist:"}

I have a lot of cases for which this is happening and it’s random, can you please check it on urgent basis?
