# Event Webhook Node.js Code Example

## Parse Webhook

This example shows how to parse inbound emails with Node.js, the Express framework, and the Twilio SendGrid Inbound Parse Webhook.

In this example, we want to parse all emails at `address@email.sendgrid.biz` and post the parsed email to `http://sendgrid.biz/parse`. We will be using Node and the Express framework.

Given this scenario, the following are the parameters you would set at the [Parse API settings page](https://sendgrid.com/developer/reply):

```bash
Hostname: email.sendgrid.biz
```

```bash
URL: http://sendgrid.biz/parse
```

To test this scenario, we sent an email to `example@example.com` and created the following code:

```javascript

var express = require('express');
var multer  = require('multer');
var app = express();

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.use(multer());
});

app.post('/parse', function (req, res) {
  var from = req.body.from;
  var text = req.body.text;
  var subject = req.body.subject;
  var num_attachments = req.body.attachments;
  for (i = 1; i <= num_attachments; i++){
    var attachment = req.files['attachment' + i];
    // attachment will be a File object
  }
});

var server = app.listen(app.get('port'), function() {
  console.log('Listening on port %d', server.address().port);
});
```

## Event Webhook

To use the Event Webhook, you must first [setup Event Notification](/docs/sendgrid/for-developers/tracking-events/event/#setup).

In this scenario, we assume you've set the Event Notification URL to go the endpoint `/event` on your server. Given this scenario the following code will allow you to process events:

```javascript

var express = require('express');
var app = express();

app.configure(function(){
  app.set('port', process.env.PORT || 3000);
  app.use(express.bodyParser());
});

app.post('/event', function (req, res) {
  var events = req.body;
  events.forEach(function (event) {
    // Here, you now have each event and can process them how you like
      processEvent(event);
  });
});

var server = app.listen(app.get('port'), function() {
  console.log('Listening on port %d', server.address().port);
});
```
