PHP XML Request Travelport API - php

Question

I'm trying to get a response from Travelports uAPI via XML/SOAP but i'm not just getting anything useful. print_r and var_dump and an echo all just show Resource id #2 which IS something but can't get any further.
I've tried their API Test Tool to send XML requests and it works fine but just can't get it to work in PHP. I've parsed XML before but never send requests.
Code:
<?php
$CREDENTIALS = '******************';
$message = '
<?xml version="1.0" encoding="utf-16"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

</s:Envelope>
';
$auth = $CREDENTIALS; //should base_64_encode() this!
$soap_do = curl_init("https://americas-uapi.copy-webservices.travelport.com/B2BGateway/connect/uAPI/Service");
$header = array(
"Content-Type: text/xml;charset=UTF-8",
"Accept: gzip,deflate",
"Cache-Control: no-cache",
"Pragma: no-cache",
"SOAPAction: \"\"",
"Authorization: Basic $auth",
"Content-length: ".strlen($message),
);
curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 60);
curl_setopt($soap_do, CURLOPT_TIMEOUT, 60);
curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($soap_do, CURLOPT_POST, true );
curl_setopt($soap_do, CURLOPT_POSTFIELDS, $message);
curl_setopt($soap_do, CURLOPT_HTTPHEADER, $header);
curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true);
curl_exec($soap_do);
print_r($soap_do); echo '<br>';
var_dump($soap_do);
echo '<br>'.$soap_do;
?>
Any help just to get me started would be great. :)

Answer 1

I am a Partner Technical Specialist at Travelport, and I understand your frustration. Our previous usage and description of endpoints has been confusing. There are updated PHP samples if you log into our developer portal;

The easiest is to 'Deselect All', then select specifically for 'Sample Code'.
Give those a try!

Just change
$soap_do = curl_init("https://americas-uapi.copy-webservices.travelport.com/B2BGateway/connect/uAPI/Service");
to
$soap_do = curl_init("https://americas-uapi.copy-webservices.travelport.com/B2BGateway/connect/uAPI/AirService");
