Piping emails from postfix under Plesk to Ostickets helpdesk - bash

Question

I'm trying to pipe support emails from my production mail server (Plesk 12 and Postfix) to send them to another VPS hosting my helpdesk installation, I have chosen ostickets helpdesk for many reasons (Open source,PHP/MySQL...)
So, the idea is to trigger email reception on some adresses such as contact#company.com, support#company.com... then resend them to ostickets via its API in order to create a new ticket there.
I tried this way
http://blog.absolutedisaster.co.uk/osticket-plesk-9-postfix-pipe-mail-to-a-progr/
It explains how to create a pipe to trigger email, lunch php script ...etc
Because of some permission issues, I kept all this configuration and change just the last thing : php script
So I've replaced this php script by a simple bash script doing the same thing : send a request to API to create a new ticket via CURL.
Now In my production mail server the pipe is recognized and the email is trigged successfully :
The same in the other side, osticket API is receiving the request:
The problem is that the http response is 400 as you can see, which means ans error code #66 in ostickets (malformed email).
So, I think the problem is in my bash script :
exec curl --header 'X-API-Key: API_KEY_HERE' --user-agent 'osTicket API Client v1.7' --data - 'http://support.company.com/api/tickets.email'
the original PHP script I have replaced by this is :
#!/usr/bin/php -q
<?php
# Configuration: Enter the url and key. That is it.
# url => URL to api/tickets.email e.g http://yourdomain.com/support/api/tickets.email
# key => API's Key (see admin panel on how to generate a key)
#
$config = array(
'url'=>'http://support.company.com/api/tickets.email',
'key'=>'API_KEY_HERE'
);
#pre-checks
function_exists('file_get_contents') or die('upgrade php >=4.3');
function_exists('curl_version') or die('CURL support required');
#read stdin (piped email)
$data=file_get_contents('php://stdin') or die('Error reading stdin. No message');
#set timeout
set_time_limit(10);
#curl post
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $config['url']);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_USERAGENT, 'osTicket API Client v1.7');
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Expect:', 'X-API-Key: '.$config['key']));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result=curl_exec($ch);
curl_close($ch);
//Use postfix exit codes...expected by MTA.
$code = 75;
if(preg_match('/HTTP\/.* ([0-9]+) .*/', $result, $status)) {
switch($status[1]) {
case 201: //Success
$code = 0;
break;
case 400:
$code = 66;
break;
case 401: /* permission denied */
case 403:
$code = 77;
break;
case 415:
case 416:
case 417:
case 501:
$code = 65;
break;
case 503:
$code = 69;
break;
case 500: //Server error.
default: //Temp (unknown) failure - retry
$code = 75;
}
}
exit($code);
?>
What is missing in my bash script ? (especially the stdin input)
thank you so much,
UPDATE
The problem was indeed in the bash script, here is the solution I came up with:
#!/bin/bash
data=`cat -`
exec curl --header 'X-API-Key: API_KEY_HERE' --user-agent 'osTicket API Client v1.7' --data "$data" 'http://support.company.com/api/tickets.email'
