Akamai clear cache after publishing

I'm publishing data from php code to Akamai CDN. I'm looking for a way to clear cache of my data after publish is completed. Can I do it from Akamai user interface? Or should I implement it in my php app?

After few hours of researching and after that I got login credentials to ACCU. This is the snippet that made purge working for me:

    $data = array("type" => "arl", "action" => "invalidate", "objects" => array($file));
    $data_string = json_encode($data);
    $ch = curl_init('https://api.ccu.akamai.com/ccu/v2/queues/default');
    curl_setopt($ch, CURLOPT_USERPWD, "aaa:bbb");
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));

    // Send the request & save response to $resp
    $resp = curl_exec($ch);
    // Close request to clear up some resources
    curl_close($ch);

Thanks all for the help and the guidance
