ngrok is an awesome service – it creates secure tunnels to localhost. Zen den. With ngrok, you get a url like http://459387bb.ngrok.com which is actually tunnel to a port to your local machine. So any request you make to that url is served by the app that you run on that port.

I know there are many cool services to debug webhooks like Requestbin – but the main benefit of ngrok is the app keeps running on your app, serving live traffic. So you can debug it in real time.

Tunneling Traffic

Ngrok Mac

Once we have the app running on port 3K, we can ask ngrok to create a tunnel for us. For this we just need to pass the port number to the ngrok command:

Download Ngrok

We would get an url soon afterwards. We can use this url to POST requests. In our case, go to your Mandrill account and create a webhook. Mandrill will send events to this url and it will be served by your app, running locally on your machine. You can make changes to the codes and restart anytime.
