I'm trying the same as the user to complete the purchase redirect you to a page. I used the code @Javier
$ App = JFactory :: getApplication ();
$ App-> redirect ( 'http://test.net/test/test);
but this does not work. As is actually written?, my knowledge of php are rather scarce.
This is how it looks now
<?php

defined('_JEXEC') or die('Restricted access');
?><?php
$app = JFactory::getApplication();
$ App-> redirect ( 'http://test.net/test/fin-de-compra');
