Passing XML code to Get Repose from API using Coldfusion

I had the following PHP code that posts XML data and retrieves the status as successful post or not This is a valid code and running fine using PHP. This code was sent by the company to test the api, but as the development is done using ColdFusion I wrote a code, given below in ColdFusion, Its sends an OK response but returns an error code as per behavior or the API.

PHP Code:

<?php
define('blueEx', "http://benefit.blue-ex.com/api/post.php");
$xml = '<?xml version="1.0" encoding="utf-8"?>
<BenefitDocument>
<AccessRequest>
<DocumentType>1</DocumentType>
<TestTransaction>Y</TestTransaction>*For Testing purpose, after testing leave it blank

$c = curl_init(); 
  curl_setopt($c, CURLOPT_URL, blueEx );
  curl_setopt($c, CURLOPT_RETURNTRANSFER, 1 );
  curl_setopt($c, CURLOPT_USERPWD, "sphere.technologies:sphere.tech");
  curl_setopt($c, CURLOPT_POST, 1 );
  curl_setopt($c, CURLOPT_POSTFIELDS, array('xml'=>$xml) );
  curl_setopt($c, CURLOPT_HTTPHEADER, array('Content-Type=application/soap+xml', 'charset=utf-8'));
  $result = curl_exec ($c);
  $xres = simplexml_load_string($result);
  $st = $xres->status;
  $no = $xres->message;

  echo $st . ' - ' . $no;
?>
