title: Read a Google Sheet with Python using API Key instead of OAuth Client ID [Python]
body: <p>While there are several useful articles on how to use OAuth Client IDs to generate credentials needed for reading and writing to Google Sheets, I have been unable to make sense of how one would use the alternative API Key (token) in such a context.</p>
  
  <p>I've blindly attempted to simply pass the token string into <code>gspread.authorize(TOKEN)</code> but, not surprisingly, received an error: <code>AttributeError: 'str' object has no attribute 'access_token'</code></p>
  
  <p>Thanks in advance for any advice</p>
