How to use the parse.Parse function in parse

// Parse Cloud Code Webhooks example for Express JS

// Require Node Modules
var https = require('https'),
    fs = require('fs'),
    express = require('express'),
    bodyParser = require('body-parser'),
    Parse = require('parse').Parse;

// Load SSL Certificate details, and the apps Webhook key
var privateKey = fs.readFileSync('private-key.pem'),
    certificate = fs.readFileSync('certificate.pem'),
    webhookKey = fs.readFileSync('webhook.key').toString().trim();

var serverOptions = {
  key: privateKey,
  cert: certificate
};

// Express middleware to enforce security using the Webhook Key
function validateWebhookRequest(req, res, next) {
  if (req.get('X-Parse-Webhook-Key') !== webhookKey) return errorResponse(res, 'Unauthorized Request.');
  next();
}
