fantasysports

Hi,

I am working on an app for providing users with analytics and visualizations for their fantasy leagues and am having some problems. I have created an app in the Yahoo Developer dashboard and it works for my yahoo account however when other accounts try to use my app there are errors saying that additional credentials are required. Is this intended and is what I am trying to achieve impossible or perhaps I am doing things incorrectly. Users are able to login via oauth however trying to call any of the fantasy api's gives this error. I am happy to provide more details if needed.

Thanks

K
