invalid_client error

[shahtalebi]

Hello,
I am trying to use the fetch_token method as in the code snippet you provided in the "Authenticating with OAuth" section, but I constantly get InvalidClientError: (invalid_client) error.
Is there any particular action that I have to take to proceed with downloading high quality files?

Hi @shahtalebi,
Are you sure you are using the correct client id (not the client secret) and passing all requested parameters? Maybe you can paste your request code here (removing sensible data) so I can help.
