Roblox Web API: How to Auth with Cookie?

[callmehSpear (Ted)]

I am trying to use this API:
https://users.roblox.com/v1/users/authenticated

What how do I add the .ROBLOSECURITY cookie into the headers?

Well how do I auth with the API then?

headers = {
    Cookie: ".ROBLOSECURITY=cookie value here" 
}
