Hi @fundacionalcoactivid,

Thanks for reaching out about this, and happy to help.

Typically, a 400 response means something in the request URL is invalid or there could be an issue with your environment. Can you confirm that the registrant ID you’re passing is for a valid registrant for an upcoming meeting? Additionally, when you call the GET Meeting endpoint, can you confirm the occurrence ID for this recurring meeting matches that to which the registrant belongs?

Lastly, have you tried sending this request directly from Postman or cURL to see if you get the same result?

Let me know—Thanks!

Will, thank for your response. I confirm that the id’s are correct, the registrant_id and occurence_id.
All request tried in web of zoom request platform.


Hey @fundacionalcoactivid,

What HTTP method are you using for this request? GET, POST, PATCH, DELTE, etc?
