How to write code for InCall and AfterCall webhook url for Myoperator

InCall Webhook Myoperator

public function inCallWebhook(Request $request)
{
  $data = array();
  $data['data'] = json_decode(Request::createFromGlobals()->getContent());
  $input = array();
  try{
  $input['incall_id'] = $data['data']->id;
  $input['uid'] = $data['data']->uid;
  $input['reference_id'] = $data['data']->reference_id;
  $input['company_id'] = $data['data']->company_id;
  $input['clid_raw'] = $data['data']->clid_raw;
  $input['clid'] = $data['data']->clid;
  $input['rdnis'] = $data['data']->rdnis;
  $input['call_state'] = $data['data']->call_state;
  $input['event'] = $data['data']->event;
  $input['status'] = $data['data']->status;
  $input['users'] = $data['data']->users;
  $input['created'] = $data['data']->created;
  $input['call_time'] = $data['data']->call_time;
  $calIncallWebhook = new CalIncallWebhook($input);
  $calIncallWebhook->save();
  }
  catch(Exception $ex)
  {
  $fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/public/incall.txt","w");
  //fwrite($fp, Request::createFromGlobals()->getContent());
  fwrite($fp, $ex->getMessage());
  fclose($fp);
  }
 
 return $this->sendResponse($data, 'Successfully');   
}

AfterCall Webhook Myoperator

public function afterCallWebhook(Request $request)
{
  $data = array();
  $data['data'] = json_decode(Request::createFromGlobals()->getContent());
  $input = array();
  try{
  $input['aftercall_id'] = $data['data']->_ai;
  $input['company_id'] = $data['data']->_ci;
  $input['caller_cr'] = $data['data']->_cr;
  $input['caller_cl'] = $data['data']->_cl;
  $input['calllocation_se'] = $data['data']->_se;
  $input['status_su'] = $data['data']->_su;
  $input['call_st'] = $data['data']->_st;
  $input['call_et'] = $data['data']->_et;
  $input['time_ss'] = $data['data']->_ss;
  $input['duration_dr'] = $data['data']->_dr;
  $input['calltype_ev'] = $data['data']->_ev;
  $input['reference_ri'] = $data['data']->_ri;
  $calAftercallWebhook = new CalAftercallWebhook($input);
  $calAftercallWebhook->save();
  }
  catch(Exception $ex)
  {
  $fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/public/aftercall.txt","w");
  //fwrite($fp, Request::createFromGlobals()->getContent());
  fwrite($fp, $ex->getMessage());
  fclose($fp);
  }
  return $this->sendResponse($data, 'Successfully');     
}

public function InCallWebhookCode(Request $request)
{
  $data = array();
  $data['data'] = json_decode(Request::createFromGlobals()->getContent());
  $fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/public/incall.txt","w");
  fwrite($fp, Request::createFromGlobals()->getContent());
  fclose($fp);  
  return $this->sendResponse($data, 'Successfully'); 

}

public function inCallWebhook(Request $request)
{
  $data = array();
  $aaaa['raw'] = json_decode(Request::createFromGlobals()->getContent());
  $data['data'] = json_decode($aaaa['raw']->message->data);
  $fp = fopen($_SERVER['DOCUMENT_ROOT'] . "/public/incall.txt","w");
  fwrite($fp, Request::createFromGlobals()->getContent());
OR
  fwrite($fp,  $aaaa['raw']->message->data);
  fclose($fp);
  return $this->sendResponse($data, 'Successfully');   
}
