Zoom Meeting ID is invalid error-HTTP Status 3001

We have integrated zoom in our application. When we try to get the participant details we are getting the below error.

When the instructor/host is the only attendee, it should reflect in the participants list.

{ “code”: 3001,
“message”: “Meeting does not exist: cmiSCZ3fR9mJw0cccW0wPQ==.”

Which App Type (OAuth / Chatbot / JWT / Webhook)?

Which Endpoint/s?

How To Reproduce (If applicable)
Steps to reproduce the behavior:

  1. Set up a live chat
  2. Joined as a host, No participants has joined.
  3. Host awaited and ended the meeting.
  4. It should return the host details in participants list.

Hi @qadonotreply05,

Thanks for reaching out about this, and happy to clarify.

As it turns out, this endpoint will not return participant info for meetings with just 1 participant, which is currently expected behavior. Currently, only our List Meeting Participants (with query parameter pastOne) will return meetings with 1 participant:

I hope this helps to clarify,

Hi Will,
Thanks for the quick response.

Do i have to call like below -

  1. Do GET by additional param - type=past
  2. if it throws error ‘3001, Meeting does not exist’ Do GET again with type=pastOne
  3. It will return the single participant detail.

is there any other way to get the list in single stretch?


Hi @qadonotreply05,

That’s correct, you would need to use type=pastOne. The logic you’ve shared would be my suggestion as well.
