+const bodyParser = require("body-parser");
+const MessagingResponse = require("twilio").twiml.MessagingResponse;
+
+const authToken = process.env.TWILIO_AUTH_TOKEN;
+
+const express = require("express");
+const app = express();
+const port = 3000;
+
+app.use(
+  bodyParser.json({
+    verify: (req, res, buf) => {
+      req.rawBody = buf;
+    },
+  })
+);
+
+app.get("/", (req, res) => {
+  res.send("Hello World!");
+});
+
+app.post("/message", twilio.webhook(authToken), (req, res) => {
+  // Twilio Messaging URL - receives incoming messages from Twilio
+  const response = new MessagingResponse();
+
+  response.message(`Your text to me was ${req.body.Body}.
+                    Webhooks are neat :)`);
+
+  res.set("Content-Type", "text/xml");
+  res.send(response.toString());
+});
+
+app.listen(port, () => {
+  console.log(`Example app listening at http://localhost:${port}`);
+});
