This is what i'm looking for but this documentation seems outdated... I am logged into my developer account as well as the myspace account associated with my specific application (on a separate browser). I don't see any place where I can create a notification to send out to all my players.There...

I'm getting 409 response code when sending notification via REST API for a one app, for other apps everything is ok, notifications are send without problem. errormessage - The page was not displayed because there was a conflict.
