In order to receive the details of a booking the client system has to send the booking reference in a query with type attribute set to track.
The only data to send back are booking and client reference.
<?xml version="1.0" encoding="UTF-8"?>
<envelope>
<header>
<actor>test</actor>
<user>test</user>
<password>test</password>
<version>1.6.1</version>
<timestamp>20030423170100</timestamp>
</header>
<query type="track" product="hotel">
<reference code="BOOK2005 000001"/>
<booking name="2014-1241"/>
</query>
</envelope>
You can perform a tracking request using one of the two parameters between reference code and booking name. The response is pretty close to the feedback received after the booking stage: a tracking message will describe the status of the booking.
