SkyScanner API error when called by PHP - php

Question

I did exactly as shown in the API documentation
http://business.skyscanner.net/portal/en-GB/Documentation/FlightsLivePricingList
but when i call it returns this error
HTTP/1.1 100 Continue HTTP/1.1 500 Internal Server Error Cache-Control: private Content-Type: application/json Date: Sat, 04 Jun 2016 06:23:48 GMT Connection: close Content-Length: 2 {}
and here is my code in PHP
<?
$url = 'http://partners.api.skyscanner.net/apiservices/pricing/v1.0/';
$data = array('apiKey' => 'de995438234178656329029769192274', 'country' => 'BR', 'currency' => 'BRL',
'locale' => 'pt-BR', 'originplace' => 'SDU-iata', 'destinationplace' => 'GRU-iata', 'outbounddate' => '2016-09-23',
$headers = 'Content-Type: application/x-www-form-urlencoded; charset=UTF-8';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded', 'Accept: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
printf($result);
?>
any idea what is going wrong?
thanks in advance for any kind

So I think the PHP is sending the wrong request type, because the HTTP headers were being sent as an array (so defaults to 'multipart/formdata'). If you use http_build_query on that array, it is sent correctly as 'x-www-form-urlencoded'.
I've tidied things up, removed some duplication in the curl options, and correctly get a 201 response on your example now:
<?
$url = 'http://partners.api.skyscanner.net/apiservices/pricing/v1.0/';
$data = array('apiKey' => 'de995438234178656329029769192274', 'country' => 'BR', 'currency' => 'BRL',
'locale' => 'pt-BR', 'originplace' => 'SDU', 'destinationplace' => 'GRU', 'outbounddate' => '2016-09-23', 'locationschema' => 'Iata', 'adults' => 1);
$httpdata = http_build_query($data);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $httpdata);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded', 'Accept: application/json'));
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);
?>
