OAuth app, same issue, {“code”: -1,“message”: null} on attempt to create registrant. The error occurs only for some accounts, cannot reproduce on my test account.

Hey @hsintegration, @Ian_SITNB

Can you share the request body payload JSON and the meetingUUID so I can look to see if meeting registration was enabled?

Thanks,
Tommy

Hi @tommy,
POST: https://api.zoom.us/v2/webinars/97401033545/registrants
Body:
{
“email":"test1@gmail.com”,
“first_name”: “TEST”,
“last_name”: “TEST”,
“phone”: “1111111”
}
Result: 400 Bad Request
{
“code”: -1,
“message”: null
}

Same issue here with the same return. It worked 2 days ago. Same endpoint is working with Zoom Meetings but not with Webinar. Meeting registration is definitely enabled.

conventionline · July 23, 2020, 3:17pm

I’m having the same issue. Everything was working fine 3 days ago.

This is what I get when I try to add a registrant to a webinar:

{"code":-1,"message":null}

Also status code 400.

  "email":"test1@gmail.com",
  "first_name": "TEST",
  "last_name": "TEST",
  "phone": "1111111"

I tested in Postman with the exact request & spacing.

Request:

{

“email”: “test1@gmail.com”,

“first_name”: “TEST”,

“last_name”: “TEST”,

“phone”: “1111111” }

Response status:

400 Bad Request

Hey @ecc,

Can you please provide your Zoom account number, and your OAuth / JWT App Name?

Thanks,
Tommy

ecc · July 23, 2020, 4:32pm

Support is providing you with the account details in ticket# 6874839

tommy · July 23, 2020, 4:40pm

Hey @ecc, @conventionline, @Ian_SITNB,

It looks like this issue is happening when the Webinar is set to a paid webinar via our PayPal integration.

Can you all confirm?

In the meantime our engineering team is looking into the issue. (ZOOM-179755)

Thanks,
Tommy

ecc · July 23, 2020, 5:12pm

Issue is still happening when Paypal is turned off. Also we were able to call out to Zoom Webinar with Paypal enabled ~3 days ago. Thanks for all your help!

conventionline · July 23, 2020, 5:32pm

No, my webinar is free, but registration required, manual approval. We’re using a different payment system.

My account number: 110825407
App Name: RegistroAutomatico

I tested it again via Test Request on Zoom API Reference, but it returned the same thing again

michael_p.zoom · July 23, 2020, 11:19pm

@ecc @conventionline Can you provide your full request payload in cURL format (without token)?

ecc · July 23, 2020, 11:40pm

Michael,

Please reference Zoom support case [#6874839] for all those details or Tommy Gaessler on your team as he was working on the case today. Thanks for you assistance!

Ian_SITNB · July 24, 2020, 1:34am

I raised a ticket on Monday #6821441. I didn’t get a single response until webinar is finished yesterday. Quite disappointed.

It seems this issue happens to certain webinar/meeting created in a certain time frame. The webinar which had API issue was created on last Thursday.

I created another webinar on Monday and it’s working fine.

Ian_SITNB · July 24, 2020, 6:48am

@michael_p.zoom @tommy
It’s “Restrict number of registrants.” If it’s turned on API return -1. Turned it off then everything works fine.

conventionline · July 24, 2020, 12:49pm

@Ian_SITNB I turned it off, and it worked!

Thank you! Been struggling with this all morning.

I turned off the restrict registrant count and all is swell on the existing webinars. This came out of nowhere and glad I saw this post.

I created a new webinar and no issue…but if I turn on the “Restrict number of registrants" for the new webinar, the API will return the -1 code for adding registrants.

tommy · July 28, 2020, 10:15pm

Hey @joedone, @conventionline, @Ian_SITNB, @ecc,

The issue was due to the “Restrict number of registrants” setting. We fixed the bug on Sunday and it will work now.

Thanks for all your patience,
Tommy
