API for creating child folder in alfresco

Question

I have a php script that will make curl request to my local copy of Alfresco to create folder. But, the response is 'bad request'. Below is my script,

<?php

$url = 'http://admin:admin123@localhost:8080/alfresco/service/api/site/folder/mysite/documentLibrary';

$postfields = array(
   "name"=> "abc",
);    

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_COOKIESESSION, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($postfields));
$return = curl_exec($curl);
curl_close($curl);
echo $return;
?>

I get the below response:

 {
    "status" : 
  {
    "code" : 400,
    "name" : "Bad Request",
    "description" : "Request sent by the client was syntactically incorrect."
  },

What am I doing wrong?

Ok, figured this one out. For others who might be facing the same issue (or just as a reference for future), what is really needed is to set the proper request header!

curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
