I saw GetGlobalStatsForGame WEBAPI in
https://developer.valvesoftware.com/wiki/Steam_Web_API
I want some global stats for CSGO but i dont know the param NAME Can any one tell me what's the param for name[0] or where I can get the name list?
If you looking for the name argument is the name of the stat you want to retrieve.
For example if you want to retrieve the "Total Galil AR Kills" you would do something like this:
http://api.steampowered.com/ISteamUserStats/GetGlobalStatsForGame/v0001/?format=json&appid=730&count=1&name[0]=total_shots_galilar
However, I do not think CSGO aggregates "global" stats. For a single game you can go to the site SteamDB and check the stats pages:
https://steamdb.info/app/730/stats/
