Welcome to the unofficial Yahoo Fantasy Sports API Documentation

This is a work-in-progress but begins as a copy of the archived documentation that lives here:

https://web.archive.org/web/20130622015733/http://developer.yahoo.com/fantasysports/guide/

As unfortunately the guide is no longer online/maintained despite the REST API being active.

In the future this guide may upgrade the documentation to include additional resources that apply today; such as OAuth related changes.
