I want to create contact group for user. I am using oauth 2.0. I have added 'https://www.google.com/m8/feeds' scope also.
Below is my code.
contactService.setAuthSubToken("access Token");
But i am getting below exception.
<p>Your client does not have permission to get URL <code>/m8/feeds/groups/abc@xyz.com/full</code> from this server.
<ins>That's all we know.</ins></p>
