<h3>Translations</h3>
<p>Notice that the JSON response for trail requests includes available translations under the key <code>translations</code>. In the request illustrated above, Spanish (es) is listed as an available translation. In order to retrieve this translation, we will send a <code>GET</code> request: <code>GET <?php
echo $baseurl;
?>
api/translation/?id=2&lang=es</code></p>
<pre>
<?php
echo json_encode($GetTrail->getTranslation("es", "Array"), JSON_PRETTY_PRINT);
?>
