Trying to create a slash command in hipchat following https://developer.atlassian.com/hipchat/tutorials/building-a-simple-add-on-using-a-wizard
I created my own http server responding to : "http://localhost:8000/test"
However, when I fill this url in the slash command attributes the messages are not being caught in my web server
any idea why it's not working ? does the url must be public so the hipchat servers will be able to have access to ?
