We’re happy to announce the availability of our Google Contacts Data API that gives programmatic access to your contact list. The contact list is shared among Google applications like Gmail, Reader, Calendar, and more.
The Google Contacts Data API allows you to own your own contact data. We expect the API to be useful for a big range of applications. For example, developers can use it to:
- Import a user’s Google contacts into their web or desktop application
- Export their application’s contact list to Google
- Write sync applications for mobile devices or popular, desktop-based contact management applications
