You don't need to know that port number. Within the process, Heroku requires you to bind that process. But their router will expose ports 80 and 443 and route requests properly to the process(es) running your app.

In order words: you bind to $PORT in a single process. Heroku's router binds to 80 and 443, and routes to one of many processes (or dynos).

All you have to do is make a request to your-app-name.herokuapp.com.
