Hello, Please have a look at the developer's guide as it explains how to delete<http://code.google.com/apis/contacts/docs/3.0/developers_guide.html#Deleting>a contact. If you don't want to delete a contact but remove this contact from a group, you should only update this contact by removing the reference to the group you want to remove.
