Hey! I have tried using your code but got error on "HTTP.Request someRequest = new HTTP.Request( "get", "http://ip-api.com/json" );" and its saying "error CS0234: The type or namespace name Http' does not exist in the namespace System.Net'. Are you missing an assembly reference?" I have tried to solve it by using "System.Net.Http" and added dll for it but failed.Please Help me in this regards. Thankyou

Thanks! Very useful indeed.
I was able to use your code to make a PlayMaker action to detect the user's country!
Nice work.
:D

ThunderboxEntertainment: I'm having the same issue as Zaidiii. How did you solve it?

Http library is available since 4.6 .Net version. For older version you have to use old Unity way to request data: https://docs.unity3d.com/Manual/UnityWebRequest-RetrievingTextBinaryData.html

@Zaidiii / @ThunderboxEntertainment / @IridiumStudios / @regy42 - I have only just seen these comments..

I’m not actively developing in Unity any more, and I can't remember the library that was used for this sample.

I would suggest using a library like Best HTTP, this will make things work better cross-platform:
https://assetstore.unity.com/packages/tools/network/best-http-10872

I hear that net standard libraries are coming to Unity if that is the case the built-in HTTP ones might work, but don't take my word for it :)

How many request we can make with our game to http://ip-api.com/json ?
