What is the Contacts Data API?
The Google Contacts Data API allows client applications to view and update Contacts content in the form of Google Data API feeds. Your client application can request a list of a user's contacts, edit or delete content in an existing contact, and query the content in an existing contact.
Here are some of the things you can do with the Contacts Data API:
- Synchronize Google contacts with contacts on a mobile device
- Maintain relationships between people in social applications
- Give users the ability to communicate directly with their friends from external applications using phone, email, and IM
