Youtube API 401 Error - php

Question

I'm using the Youtube API to try some things out and I can't get to do anything without getting the error. Expected response code is 200, got 401: User authentication required.
I have authenticated my Youtube channel though
session_start();
$clientLibraryPath = 'Youtube/library';
$oldPath = set_include_path(get_include_path() . PATH_SEPARATOR . $clientLibraryPath);
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata_YouTube');
$yt = new Zend_Gdata_YouTube();
Zend_Loader::loadClass('Zend_Gdata_AuthSub');
function getAuthSubRequestUrl()
{
$next = 'LINK';
$scope = 'http://gdata.youtube.com';
$secure = false;
$session = true;
return Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session);
}
function getAuthSubHttpClient()
{
if (!isset($_SESSION['sessionToken']) && !isset($_GET['token']) ){
echo 'Login!';
return;
} else if (!isset($_SESSION['sessionToken']) && isset($_GET['token'])) {
$_SESSION['sessionToken'] = Zend_Gdata_AuthSub::getAuthSubSessionToken($_GET['token']);
}
$httpClient = Zend_Gdata_AuthSub::getHttpClient($_SESSION['sessionToken']);
return $httpClient;
}
getAuthSubHttpClient();
$cID = "Client ID";
$aID = "App ID";
$dK = "DEV KEY"; // Hidden
$yt = new Zend_Gdata_YouTube($httpClient, $aID, $cID, $dK);
Anyone know what I'm doing wrong here to login into my account?

Make sure you have your code hosted in the exact same URL as you set in the Google Code Console
If your javascript origins is set to http://example.com, make sure your code isn't being hosted at http://example.com/something or http://something.example.com! This seemed to work for me :)
