Как я могу заставить работать Yahoo OAuth при локальной разработке, когда мой локальный домен не зарегистрирован в Yahoo?

Я работаю над приложением, которое использует Yahoo OAuth. "Custom port is not allowed or the host is not registered with this consumer key."

The issue is because my call back URL is to a domain that is not registered with Yahoo (http://localhost:8080/welcome).

I'm not sure what to do. I'm also new to development so if you could be specific with suggestions that would be awesome! Any help is greatly appreciated.
