The Domain Shared Contacts API feed is a private read/write feed that an administrator can use to view and manage a domain's shared contacts. Because the feeds are private, you can access them only by using an authenticated request. The request must contain an authentication token for a domain administrator. For more information about authenticating, see Learn about authentication and authorization.
Projection values indicate what data is included in the representation of a contact. For a list of values, see Projection values.
The URL for a contact feed has the following form:
https://www.google.com/m8/feeds/contacts/DOMAIN/PROJECTION
Replace the following:
DOMAIN: The URL for your domain—for example, example.com.PROJECTION: The projection value that specifies thegd:extendedPropertyelements. For a list of supported values, see Projection values.
