DO NOT USE THIS TAG ALONE. Use for questions regarding programmatic manipulation of Google Apps Scripts through the REST-Google Apps Script API. Use in addition to the language tag (like [python], [java], [c#]) and the google-api library tag(like [google-api-java-client]) that is used to do the said manipulation.
The Apps Script API offers programmatic control of Google Apps Script projects to 3rd party applications via a REST API. It is an extension of the previous "Execution API," now enabling client applications to perform actions that were previously only available inside the Apps Script editor, such as create projects or manage deployments.
