title: How to start buidling and app using stackexchange API as it does not support localhost?
body: <p>How can I use <a href="https://api.stackexchange.com/docs/authentication">Stackexchange API</a> when it does not support localhost or any dev URL with port number?</p>
  
  <p>It is very difficult to push code to Heroku as it was suggested in one answer on StackOverflow during development as it slows down development work.</p>
  
  <p>I have registered my application with the API but I cannot specify port number there and therefore I cannot implement the functionality of importing user data into my Rails app.</p>
