DataLayer.Google Spreadsheet - Getting a Google API Key
In order to use the DataLayer.Google Spreadsheet in your application, you'll need a Google API key for the Sheets API.
In July 2018, Google changed its licensing scheme, ending the free API access previously offered at some usage levels. This specifically affected geocoding in Logi applications. Information about how to get a Google Sheets API key is available in Google Connections. Please read that topic and take the necessary steps before proceeding to use data from Google Spreadsheets in your Logi application.
