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:
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
Followup up here with another wrinkle:
Sometimes the 404 response includes the 1001 error code, and sometimes there is no error code or any additional context.
Here are recent tracking ids for 404 response with error code:
v=2.0;clid=us06;rid=WEB_0ab3a1ebba3afe9cbbab92c22bfb0d61
v=2.0;clid=us06;rid=WEB_dde98b92a24f1214da908143dc460b17
v=2.0;clid=us06;rid=WEB_0642d4fbba0c5433b30da2ae75f75e49
And here are recent tracking ids for 404 response without any error code:
v=2.0;clid=us06;rid=WEB_5d766faafc427b56e080b0089625f192
v=2.0;clid=us06;rid=WEB_9467039f05a855dfeb486fc39b2ea01e
@Elisa any input here?
my zoom support tickets have not led to anything helpful.
seems like this forum is my only hope.
Would love to have some help navigating this issue please and thanks Zoom
Hi @Aaron5
Thank you for your patience and apologize for the late reply here.
I reported this to our Engineering team ( ZSEE-195502 internal ticket number for reference)
I will get back to you as soon as I have an update from the team
Hi, thanks @elisa.zoom - any updates for me ?
Hi Aaron, I do not have any updates at themoment but I have re engaged with the engineering team and hoping to hear back from them soon
Hey @Aaron5
The Engineering team updated me and said that this error is expected, which I believe it should not, since the endpoint you are calling is the Add a registrant endpoint
Would you happen to have a more recent tracking ID when you get this error “user does not exist” when calling the Add a registrant endpoint so I can share this new request to our team?
It could also be a screenshot of the issue if you have it
Here are 3 tracking IDs from this morning with 404 errors, all with the “1001: User does not exist” error code:
v=2.0;clid=us06;rid=WEB_3ded153a20c8d1a47fbd409db0590574
v=2.0;clid=us06;rid=WEB_4d9dca36f0aa521e8a0b21ca61bc6b51
v=2.0;clid=us06;rid=WEB_3df22ed3db5fe0b57d421105674e0da1
All 3 are POSTs to the endpoint webinars/{webinar_id}/registrants
All 3 contain email addresses which are not already registered to the webinars, though may have been registered for other webinars.
The requests are to 2 separate webinars, ids 88103772725 and 86836646266, each 3000-attendee capacity and less than 500 registrants for each, most of whom have been registered successfully with the same endpoints.
I have 71 failed registrations for webinar 88103772725 and 85 failed registrations for webinar 86836646266.
I’m not sure what other information I can provide, but please let me know what might be helpful.
That said, by far the more prevalent error (4x as often) is 429 Too many requests, described elsewhere. Just in the past 2 hours, 16 registrations have failed to post with 429 errors.
Thanks @Aaron5
I just added this new information to the ticket ZSEE-195502
Hi @Aaron5
Thanks for your patience here
I just heard back from our Engineering team and they shared the following:
There are two possible causes for the issue you are seeing:
1.the webinar host does not exist.
2.webinar enables meeting authentication with login to join, if the registrant email was not a zoom user email.
Then the error “user does not exist” pops up.
Given that 300 other registrations were posted successfully, i think we can rule out #1
Is that this setting on the webinar “Require attendees to authenticate to join”?
And, in order to register for a webinar, a zoom user for the registrant email must exist beforehand?
Seems like this would be a useful information to have in the documentation for this endpoint.
Looks like there’s no API for me to confirm whether an arbitrary user exists, and no way for me to create an account on the user’s behalf other than adding them to my zoom account (which we don’t want to do).
Can you please help me understand the options for resolving this, so that I can present to my client?
Option 1: uncheck this checkbox
Option 2, assuming they want to keep this checked: is there any way to support these registrations from the application?
Hi @Aaron5
Thanks for your patience here. Yes, you are correct If this setting is turned on, in order to register for a webinar and to avoid the error, a zoom user for the registrant email must exist beforehand.
If you want to keep this checked then you must ensure the users they’re registering are valid zoom accounts or else they will continue to get the error.
Alternatively, you can turn off the setting “Require attendees to authenticate to join”
I will make sure to make a note so our Docs team can update the documentation for the endpoint.
