I am creating a new extension to add a new SMS provider. Since different parameters are passed during callback, I need to override run method of the CRM_SMS_Page_Callback class. Since it is a part of CRM Core, what is the best way to do it?


class CRM_SMS_Page_Callback {

  public function run() {
    $provider = CRM_SMS_Provider::singleton($_REQUEST);

    if (array_key_exists('status', $_REQUEST)) {
    else {

When you say parameters do you mean http get/post parameters? You would just access those in your callback the usual way in php. Or see for example the callback function for clickatell


  • Yes, I mean GET parameters. My SMS provider does not use 'status' parameter necessary for the callback() method to fire. Dec 12, 2017 at 19:38
  • Then in your inbound() function you could also branch and call callback() as necessary.
