I am using the REST-Library Demos to learn how to get & put files to a Dropbox App. I need to setup a redirect_uri but I can't figure out what to provide.

The App setup page says this 'You must provide a proper URI with an authority or path component' and the hint is 'https:// (http allowed for localhost)';

What do I need to provide?
