Questions tagged [google-calendar-api]

Questions related to interacting programmatically with Google Calendar calendars and events. A language tag should also be included, e.g. [google-apps-script]. Questions about general use of Google Apps should be posted on Web Applications Stack Exchange.

Google Calendar is a cloud-based application and service for personal calendar management. The service supports an API for Google Apps Script, and an API for integrating with applications written in a variety of technologies (currently Java, Python, PHP, .NET, Android, Go, iOS, JavaScript, Node.js, and Ruby).

The tag should be applied to questions related to interacting programmatically with the Google Calendar service or problems with Google's API for same. An additional language tag should also be included, representing the primary application implementation language in the question, e.g. , , or .

Usage questions about the web application should be posted at Web Applications Stack Exchange instead of here.
