Description
We have an issue with a specific customer not being able to access recording or voicemail endpoints - let’s say for example https://api.zoom.us/v2/phone/recordings. The response is a 401, with “Invalid access token”
Becuase this is a 401 and not a 403 I considered that there could be a bug in our code, but we have validated that it’s a problem with specific customer (others, and our own test accounts are working fine).
Is it possible to get any more information as to what is going on here? The access token is able to call other endpoints, so it’s a correctly formatted token - we would like to be able to provide some more direct advice than “The user who installed the app does not seems to be missing some permissions that we cannot tell you”
Error
{“code”:124,“message”:“Invalid access token.”}
Which App Type (OAuth / Chatbot / JWT / Webhook)?
Oauth app
Which Endpoint/s?
https://api.zoom.us/v2/phone/recordings
https://api.zoom.us/v2/phone/users/xxxxx-user-id-xxxxx/voice_mails
How To Reproduce (If applicable)
Cannot reproduce with test accounts, is related to a specific app install.
Screenshots (If applicable)
N/A
Additional context
Is there any way I can add a tracking header to perform the request to get a bit more insight into specifically why this is failing?
Much appreciated
