Description I was trying to create webinar registrants via API. Error 400 Bad Request Body: { “code”: -1, “message”: null } Which App Type (OAuth / Chatbot / JWT / Webhook)? JWT Which Endpoint/s? POST: https://api.zoom.us/v2/webinars/xxxxxxxxx/registrants How To Reproduce (If applicable…

@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.

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.

Hey @Ian_SITNB , @ecc , @conventionline , I am not able to reproduce the issue: POST https://api.zoom.us/v2/webinars/95197907800/registrants { "email":"test1@gmail.com", "first_name": "TEST", "last_name": "TEST", "phone": "1111111" } Status 201 Response: { "registrant_id": "gBQKCFcNSK…

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 [Postman response to test]

Hey @ecc , Can you please provide your Zoom account number, and your OAuth / JWT App Name? Thanks, Tommy

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

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

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.
