Hi @nguyenann13
Thanks for reaching out to the Zoom Developer Forum, I am happy to help here!
From the request URL that you are sharing here, I noticed that you did not include the “to” parameter, could you please add it as its a required field and try again.
Best,
Elisa
Even with the ‘to’ parameter it is not returning
Hi @nguyenann13
Thanks for reaching out back to me.
Make sure to add tracking fields when scheduling the meeting so you will be able to see them in your response.
