Use chrome
F12 or console window.
I made this for TS1 try to make something similar for TS2 by looking at how their game launch button gets the paramaters for launcher then adapt the below.
It will be in one of the js files.
Copy paste into chromes console window
$.post(APPLICATION_CONTEXT + "/Launcher/auth", {
timestamp : new Date().getTime() / 1000
}, function(data){ window.location = data.launcherAuthUrl; });
Or to see the data for your self
$.post(APPLICATION_CONTEXT + "/Launcher/auth", {
timestamp : new Date().getTime() / 1000
}, function(data){ console.log(data.launcherAuthUrl); });
