Receive text message with Twilio node module and respond with a text message

var http = require('http');
var twilio = require('twilio')(ACCOUNT_SID, AUTH_TOKEN);
var qs = require('querystring');

http.createServer(function (req, res) {
  var body = '';
  req.setEncoding('utf8');

  req.on('data', function(data) {
    body += data;
  });

  req.on('end', function() {
    var data = qs.parse(body);
    var jsonString = JSON.stringify(data);
    var jsonDataObject = JSON.parse(jsonString);

    // log the received message
    console.log(jsonDataObject.Body);


      twilio.messages.create({
      to:'MY_PHONE_NUMBER',
      from:'TWILIO_NUMBER',
      body:'Hello World'
      }, function(error, message) {
        if (error) {
          console.log('There was an error.')
          console.log(error.message);
        }
      });

      res.writeHead(200, {'Content-Type': 'text/xml'});
      res.end();
  });

}).listen(1337, '127.0.0.1');

console.log('TwiML servin\' server running at http://127.0.0.1:1337/');

I'm trying to use the Twilio node module to receive a text message and in turn respond to that text message once received. There seems to be no problem receiving the message as I'm able to log the body. But, I get a 401 Authenticate error when I try and respond to that message. I'm using ngrok to expose my localhost so I can hook it into Twilio's API. Please see below:

Where am I going wrong here?

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
const MessagingResponse = require('twilio').twiml.MessagingResponse;


var server = app.listen(80, function () {
   var host = server.address().address
   var port = server.address().port
   console.log(" web app listening at http://%s:%s", host, port)


})

app.post('/txt', urlencodedParser,(req, res) => {
  const twiml = new MessagingResponse();

  twiml.message('Finally Twilio works!');
  res.status(200);
  res.send(twiml.toString());

  });

Under your phone number in the console. You can click webhooks and change it to the http://"putyourserverhere"/txt This will automatically text back the inbound user. Enjoy. Make sure you have the newest version of twilio installed.

Twilio developer evangelist here.

You actually don't need to use the REST API in order to reply to an incoming message to a Twilio number. You can, in fact, respond to the incoming HTTP request with TwiML that describes the message in response.

To do this, you need to use the <Message> verb. In your application, this would look like:

First, just require the twilio module without the account credentials:

var twilio = require("twilio");

Then, respond to the incoming request with TwiML, like so:

  req.on('end', function() {
    var data = qs.parse(body);
    var jsonString = JSON.stringify(data);
    var jsonDataObject = JSON.parse(jsonString);

    // log the received message
    console.log(jsonDataObject.Body);

    var twiml = new twilio.TwimlResponse();
    twiml.message("Hello world");

    res.writeHead(200, {'Content-Type': 'text/xml'});
    res.end(twiml.toString());
  });

Let me know if this helps at all.
