Is there any "official" tutorial about how to get the contact list of the logged in user. My customer wants me to implement the yahoo contact list getter. The user will log in and mark his/her friends. Invitation email will be sent to his/her friends.
I got the yahoo application key, secret etc but couldn't succeeded. I followed a tutorial but it seems the token is changing everytime I refresh a page. I got some "libraries" for yahoo oauth and for that thing but I didn't downloaded them from yahoo officially.
Also by the way where is yahoo email/application api link on the site: http://developer.yahoo.com/
