I don’t understand why I am getting a 404 Not Found response for a POST to webinar/{id}/registrants
I am posting user registration data to zoom, and the data does not include any user id, only email, name, etc.
The response is: {“code”:1001,“message”:“User does not exist.”}
This error is intermittent.
What can cause this error and how can i avoid it?
Hi @Aaron5
Thanks for reaching out to us
I have not seen this issue but happy to look further.
Would you be able to share a tracking ID of a failed request with us so we can look furhter into this?

Thank you for looking into it.
Here are tracking ids for a handful of recent errors:
v=2.0;clid=us06;rid=WEB_e4f2bf3e4ee8522c52fc26bb5a8886f6
v=2.0;clid=us06;rid=WEB_566da9fd82e71aa71678ef035e83d410
v=2.0;clid=us06;rid=WEB_56f68828f444b70a278cb27a8ef9f2e4
v=2.0;clid=us06;rid=WEB_02e151bcaeeaee7827b096a52f9c9df5
Lastly, though the 404 errors are confusing, the vast majority of the errors I’m seeing are 429’s.
I’ve posted those details to separate threads in case it’s helpful.
429 errors: 429 error for user who is not registered
I’m also seeing some 401 errors: 401 unauthorized errors all of a sudden, intermittently, then resolving by themselves
