Skyscanner API для всех мест в аэропортах и ​​Travel API с использованием CURL

 i have replace api key with my apikey.

PHP-код:

    <?php

$varApiKey = '?apiKey=API KEY';
$country_code = 'IR';
$originplace = '51.845159,-8.492835-latlong';
$curency = 'EUR';
$destination = 'DUB-iata';
$start_date = date('Y-m-d');
$dateOneMonth = strtotime($start_date);
//$end_date = date("Y-m-d", strtotime("+1 month", $dateOneMonth));
$end_date = '';
$audult = '1';
$cabinclass = 'Economy';
$locationschema = 'iata';
$grouppricing = $preferDirects = 'true';

$query = "&country=" . $country_code;
$query .= "&currency=" . $curency;
$query .= "&locale=en-IE";
$query .= "&originplace=" . $originplace;
$query .= "&destinationplace=" . $destination;
$query .= "&inbounddate=" . $end_date;
$query .= "&outbounddate=" . $start_date;
$query .= "&adults=" . $audult;
$query .="&locationschema=" . $locationschema;
$query .="&cabinclass=" . $cabinclass;
$query .="&preferDirects=" . $preferDirects;
$query .="&grouppricing=" . $grouppricing;$apiParamsUrl = "http://partners.api.skyscanner.net/apiservices/pricing/v1.0/" . $varApiKey . $query . "";

$apiParamsStr = parse_url($apiParamsUrl, PHP_URL_QUERY); // get the query string parametures
parse_str($apiParamsStr, $apiParamsArray);// parse into an array
// the api url. First we need to request for a session
$apiSessionUrl = 'http://partners.api.skyscanner.net/apiservices/pricing/v1.0';

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $apiSessionUrl);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded', 'Accept: application/json')); // make api return json data
curl_setopt($ch, CURLOPT_POST, count($apiParamsArray)); // set how many fiels
curl_setopt($ch, CURLOPT_POSTFIELDS, $apiParamsStr);    // set the fields
// caputre the headers
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

//execute post
$response = curl_exec($ch);// get the headers
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

//close connection
curl_close($ch);

//    print_r($response);
//    die();
// get the api session url
preg_match('~Location: ([^\s]+)~', $header, $matches);
$apiSessionUrl = $matches[1];

// add on the api key for the session
$apiSessionUrl .= $varApiKey;

// get the json data
$data = file_get_contents($apiSessionUrl);

// decode the json
$array = json_decode($data, true);

// dump json array`enter code here`
printf('<pre>Poll Data  %s</pre>', print_r($array, true));?>

после запуска кода я получаю эту ошибку
