The Contacts Data API allows client applications to view and update a user's contacts. Contacts are stored in the user's Google Account; most Google services have access to the contact list. Your client application can use the Contacts Data API to create new contacts, edit or delete existing contacts, and query for contacts that match particular criteria.
