In order to cancel a booking the client system has to send the booking references in a query with type attribute set to cancel.
<?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="cancel" product="hotel"> <reference code="BOOK2005 000001"/> <booking name="2014-1241"/> </query> </envelope>
You can ask for a cancellation sending one of the two parameters returned in the track response: reference code or booking name. The response is pretty close to the feedback received during the booking stage: so it does not confirm the cancellation but it only acknowledge the reception of the cancellation request. A tracking message will confirm the cancellation in a later stage.
