I wrote a little PHP script: (wm=PTiqU is my "campaign")
<?PHP
$json = file_get_contents('https://chaturbate.com/affiliates/api/onlinerooms/?format=json&wm=PTiqU');
//var_dump(json_decode($json));
$jsonD = json_decode($json,true);
print '$jsonD<xmp><pre>' . print_r($jsonD,true) . '</pre></xmp><p>$jsonD<p>';
?>
the file is pretty huge.
