Unable to create yahoo Application

I am a web developer and I want to add a yahoo sign in for my website. I am currently developing website and running it on local host. When I am creating the Yahoo App it is not allowing to put the address in the URL. How should I proceed?

Solution

Your site needs to be hosted on an externally facing location. Localhost doesn't mean anything to yahoo. It also looks like they won't let you enter just an IP address so they may require you to be on a domain.

If yahoo is going to be trusting you with user data they want you to be as legitimate as possible.
