I have a quiz game and I log in using Facebook SDK. In this way, I can see all my friends that play game and invite them for a match.
My question is: how to invite specific friend and send push notification to him? I have list of friends with their Fb ids, and when I click on one, I want to send push notification, so friend could click on it and compete with me.
I have read a lot on internet, but did not find anything useful. I don't want to write server code. Node or something.
Thanks!
