Recently people often asked me how to find user ID and session ID, so, I'll make a tutorial to explain briefly!
This is for every facebook game.
A little note that session ID changes like every 30min or so.
THIS METHOD ONLY WORKS IN GOOGLE CHROME
1. Right click at the spot I've circled and click "View Frame Source"
2. It will open a new tab and then click CTRL + F (Find box)
3. Type "userid' in the find box, that is your facebook id and can be called as userid too.
4. Type "sessionid" in the find box. (It will change like every 30min!!!)
Hope that'll help ya!
