In order to get data back you need to be authenticated as you appear to know. However you are tagging on the access token using &token=

the correct way to do it is &access_token=

Example:

$curl = curl_init('https://www.google.com/m8/feeds/contacts/default/full?alt=json&max-results=50&access_token='.$token->access_token);
