The Google Drive CMS is a Google Sheet with a custom menu option to publish the content of that spreadsheet to your site's API.
This template provides the Apps Scripts and basic structure to publish content to your API endpoint.
Either use the big yellow buttons on this page, or make a copy of a pre-existing Google Drive CMS template in your Drive.
On the CMS sheet of your new Google Drive CMS template add headers, which will be used as the keys in the JSON object sent to your API.
Think of these headers like field names in a database.
Open the sheet on the Spreadsheet called SETTINGS and edit the endpoint value to the API you want the Spreadsheet's content sent to.
info_outlineNote! You need to wire-up how your chosen endpoint handles the sent data. Google Drive CMS is unopinionated in this regard.
