I Gave My Site Access to My Gmail's Google Contacts... Now What?

I'm trying to use the Google Contacts API to pull a list of contacts from Gmail. I figured out how to give my site access to my Gmail account's contacts. I'm not sure what the next step is.

What do I do next to allow my site to download a list of contacts?

Thanks in advance,

John

EDIT: Not开发者_如何学Go sure if it's relevant to my question, but I am using PHP. I've read up on how Google Contacts API delivers its results in XML format, but I'm not sure how to pull it using PHP.

To get a complete list of all contacts, do the following GET

GET https://www.google.com/m8/feeds/contacts/myname%40gmail.com/full

(replacing myname%40gmail.com with the relevant gmail address.)
