# Event Webhook Node.js Code Example

## 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);
});
```
