Hi everyone, I’m encountering a 400 Bad Request error when trying to retrieve an access token using the authorization code flow in the Zoom API. I’ve verified that the authorization code and other parameters are correct, but I’m still getting this error. Has anyone faced a similar issue or can point out potential causes? I would appreciate any suggestions on how to resolve this. Thanks in advance!
