WL API Issies

Hello Polly,
Let me explain the issues ive been having with the API. 
Here is my HTML code for fetching the list id for the name 'Today':

$tomorrow_id;

$today_id;

$ch2 = curl_init();

curl_setopt($ch2, CURLOPT_URL, "https://a.wunderlist.com/api/v1/lists");


//return the transfer as a string
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_HTTPHEADER, array(
        'X-Access-Token: 346bcca426d064414b530eaab710db7e462e8a002975bcd0e0d94ffabb58',
        'X-Client-ID: ed14a2c61edd76501b1f'
    ));
// $output contains the output string
$output2 = curl_exec($ch2);
$json = json_decode($output2, true);
// close curl resource to free up system resources

curl_close($ch2);
foreach ($json as $key => $val) {
    if ($val['title'] == "Today"){
        //  echo ("Today! \n");
        $today_id = $val['id'];
    }else if ($val['title'] == "Tomorrow"){
            //  echo ("Tomorrow! \n");
            $tomorrow_id = $val['id'];
        }

}
