Google Calendar API Released

John Musser, April 20th, 2006

Google CalendarAs announced on their blog yesterday, the Google Calendar API is officially released.

The API uses their new GData, Google data API model — an XML over HTTP REST-style approach that supports RSS and Atom syndication formats. Their edit model for creating, modifying and deleting events is based on the Atom Publishing Protocol. Any language can be used to access the service but Google does provide Java and C# libraries.

DeWitt Clinton has some interesting observations about the API, including Google’s Account Authentication for Installed Applications and the Account Authentication Proxy for Web Applications, expected later this month.

That’s excellent! Since they launched it, I’ve been hoping for an API that would allow me to include the Google Calendar in Rogue Connect. I’d like to offer all members a calendar, but really don’t see the need to create a whole new service when so many excellent ones are out there already.

Daniel, I agree that it’s one of the most potentially useful APIs published in quite awhile. Will be interesting to see what folks do with it.
