Ubivox has a number of feed options, which can be used to fetch data to your website. An example is a feed containing archived newsletters. Below is an example of what to do.
<?php
// Edit these constants, to match your account
define('URL', 'https://ubivox.clients.ubivox.com');
define('LISTID', '402');
$archive_url = URL.'/feeds/archived_deliveries_list/json/list_id='.LISTID.'/';
$json = file_get_contents($archive_url);
$newsletters = json_decode($json, true);
foreach ($newsletters as $newsletter) {
print '<table width="100%>';
print '<tr>';
print '<td><a href="'.$newsletter['url'].'">'.utf8_decode($newsletter['subject']).'</a></td>';
print '<td>'.date('d/m/Y', strtotime($newsletter['send_time'])).'</td>';
print '</tr>';
print '</table>';
