**Description**  
We integrate salesforce with zoom. we use the ZOOM API to retrieve the clients attendance for the past meetings . we have the next error message only for one recurring zoom webinar.

**Error**  
{“code”:3001,“message”:“Meeting does not exist: [REDACTED].”}

API Base URL : [https://api.zoom.us/v2](https://api.zoom.us/v2)

We are sure that the zoom id and occurrence id are correct for this webinar , what means this error message and how we can resolve it ?

Just i am noticing that the UUID is containing slash /, is that the reason the API filed to retrive the meeting data ?

Hey @aalamour,

Thank you for reaching out to the Zoom Developer Forum. Just to clarify, you’re seeing this issue when using the [Zoom for Salesforce](https://marketplace.zoom.us/apps/c8ZcoziZQoaFPE8x6INBag) app, correct? Are you able to share a screenshot of the error?

Thanks,  
Max

Hey @anasalamour,

Thank you for clarifying. You’re correct, if a UUID includes a slash you’ll want to double URL encode that UUID before using it with the API:

What API are you using specifically? Are you able to provide the endpoint and method that you’re using? I’ll advise further with that information.

Thanks,  
Max
