I am developing an application that has a function to send their connections(contacts/friends) a message. I have followed the YDN's example that can be found at http://developer.yahoo.com/yap/guide/caja-ready-code-exs.html#wall_to_wall_app
However, I am having difficulties retrieving connections.
I'm currently using OpenSocial 0.9, with my app hosted on PHP Fog. I'm not sure if PHP Fog or Yahoo! has any limitation on those APIs/used. I have also successfully verified the domain.
