Making Google’s CalDAV and CardDAV APIs available for everyone

In June 2013, Google announced the public availability of its CalDAV and CardDAV APIs, reversing a prior decision to restrict CalDAV to a select group of partners due to its predominant use by a few large developers. This decision came after numerous requests from developers highlighted various use cases, prompting Google to embrace a more open approach. Both APIs, designed for accessing calendar and contact data across the web, respectively, are now integrated with the Google APIs Console, allowing developers to enable them easily in their projects. They also support OAuth 2.0 authentication, with CalDAV featuring a new endpoint for improved functionality. Piotr Stanczyk, the Tech Lead of Google Calendar APIs, emphasized the importance of providing next-generation tools that simplify developers' tasks, while also contributing to the CalConnect consortium.
