When I structure my sheet API link it returned a page not found message. I am following the structure presented in the Developer Tools (https://developers.google.com/sheets/api/guides/migration#retrieve_row_data) and yet the continues to show as unaccessible.

Is there a different struct I should follow or has google made changes to the accessibility of if the spreadsheet API?

Any suggestions would be helpful.
