The Google People API provides access to information about profiles and contacts. With the API, your apps can do the following programmatically:
- Create a new contact or a new contact group owned by the authenticated user
- Delete an existing contact or contact group owned by the authenticated user
- Get information about a contact, a contact list or list all contact groups of authenticated user
- Modify the members of a contact group owned by the authenticated user
