Hi,

And what have you done regarding authentication? You followed https://developers.google.com/identity/sign-in/web/devconsole-project or tried https://developers.google.com/classroom/guides/auth ?

Hi ThisIsYusuf, 

Google APIs use the OAuth 2.0 protocol for authentication and authorization.You need to use OAuth 2.0 to Access Google APIs.
