Back in March, Google made the announcement that it would be shutting down its CalDAV API, which allows developers to fetch Google calendar data, to the public and restricting it to only to whitelisted developers. Today the company has reversed its decision and announced on its Developers Blog that the API will continue to be available to the public.

On top of that announcement, Google is making CardDAV, the open protocol for syncing Google contacts that it introduced last year, available to everyone starting today:

In response to those requests, we are keeping the CalDAV API public. And in the spirit of openness, today we’re also making CardDAV – an open standard for accessing contact information across the web –available to everyone for the first time.

Google outlined some other updates to the APIs:

Both of these APIs are getting other updates as well:

• Integration with the Google APIs Console. To start using CalDAV or CardDAV in your project, just enable it in the Console.
• OAuth 2.0 authentication.

In addition, the CalDAV API now has a new endpoint:
