List contacts only for "My Contacts" group using Google Contacts API v3

Question

Whenever I list my contacts using Google Contacts Api v3, the query returns 480 results, while I just have 269 contacts on My Contacts list.

I'm trying to filter them so it only shows contacts from My Contacts group, so I'm querying for the groups that I have, to check My Contacts group Id. I'm using this query for that purpose:

https://www.google.com/m8/feeds/groups/default/full/

The problem is that it returns all groups except My Contacts group.

Right now I'm struggling for help... How can I get My Contacts group id so I can filter the contacts query?

Answer 1

I finally found the problem.

I was not passing the &v=3.0 parameter to the query, so the final query I had to use was:
