pushcrew - send notification with PHP curl - php

Question

This is the code:
$title = 'Du hast neue Nachricht';
$message = 'Besuch meine Website';
$url = 'https://www.bla.com';
$subscriberId = 'xxx51a002dec08a1690fcbe6e';
$apiToken = 'xxxe0b282d9c886456de0e294ad';
$curlUrl = 'https://pushcrew.com/api/v1/send/individual/';
//set POST variables
$fields = array(
'title' => $title,
'message' => $message,
'url' => $url,
'subscriber_id' => $subscriberId
);
$httpHeadersArray = Array();
$httpHeadersArray[] = 'Authorization: key='.$apiToken;
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $curlUrl);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($fields));
curl_setopt($ch, CURLOPT_HTTPSHEADER, $httpHeadersArray);
//execute post
$result = curl_exec($ch);
$resultArray = json_decode($result, true);
if($resultArray['status'] == 'success') {
echo $resultArray['request_id']; //ID of Notification Request
}
else if($resultArray['status'] == 'failure')
{
echo 'fail';
}
else
{
echo 'dono';
}
echo '<pre>';
var_dump($result);
echo '</pre>';
And I get:
dono
string(36) "{"message":"You are not authorized"}"
And nothing in the console and no other errors. The apitoken is 100% correct. What could be the trouble here? Do I have to wait till pushcrew decide to allow my website or something?
Ignore this: I must add some more text to ask this question..

Answer 1

There is typo here:
curl_setopt($ch, CURLOPT_HTTPSHEADER, $httpHeadersArray);
Correct is with
CURLOPT_HTTPHEADER
(without the S)
