Hello, Please use SSL (https) over non-SSL (http) whenever possible. Also, make sure that the user issuing the request (e.g the one specified on the xoauth_requestor_id query parameter) has write access on the domain's shared contacts (it must be an admin user).
Also, please make sure to change the "domain" component of the URL path with your domain name: https://www.google.com/m8/feeds/contacts/<DOMAIN>/full If that doesn't work, make sure that the scope " https://www.google.com/m8/feeds"; has been authorized for the 2-legged OAuth consumer key and secret.
