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](https://support.zoom.us/hc/en-us/articles/360018597111-Configuring-Zoom-Webinars-with-PayPal). Can you all confirm? In the meantime our engineering team is looking into the issue. (ZOOM-179755) Thanks, Tommy ---

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 ---

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. ---

@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. ---

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. ---

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.
