Hi,
I'm trying to build some kind of a social game in facebook, where I need that every user that has approved my APP is able to receive notifications from me.
When the user approves my App, I save his UID in the DB for future reference.
At some later time, I want to make it possible for other users find partners for a game - so I need a way to pick randomly some user from my DB and check if he's online. Then, send him a message and propose to play with the current player.
So 2 questions:
- How can I check if some user is online, using Javascript SDK? It seems that in the new Graph API I can't get the users' online status.
- How can I then send him a message and propose to play the game? When he approves to play - he is being forwarded to the game page.
Many thanks in advance,
Roman
