Google Sheets - 'invalid api developer key'

If you are having trouble connecting your Google Sheets, please check -

  1. Third party cookies are enabled in your browser. Help doc on this below:
    Third party cookies are disabled error - Stacker

  2. That there is nothing blocking Google Sheets (i.e. an extension). Test in multiple browsers and/or in incognito mode. If you are able to go through onboarding in a private window or different browser, most likely you have a browser extension that was blocking the pop-up.

If you still have issues, please:

  • Check if it’s only happening for a specific sheet
  • Check if it’s only with a specific google account (e.g. is it a standard account or do you have a business google workspace (gsuite) account)

Send this info to with screenshots of any error messages.
