PostAsync() error code 401: "Authorization has been denied for this request"

Ok so I want to know why does it give error code 401 and how to fix it

I’m trying to make a friend request system through http service but it gives me this error: https://gyazo.com/c574ba75d2e34c6793365e0e81fa4baa (“HTTP 401 (Unauthorized)”)

I’ve already looked at all the topics but they didn’t help me

local result = HttpService:PostAsync("https://friends.rprxy.xyz/v1/users/1107776636/request-friendship", "https://rprxy.xyz/users/1416129327/profile")
	print(result)

You can’t really do that inside of a game. That is used mostly for automation, like in discord bots. Even if you wanted to, you would need a ROBLOSECURITY. You can do it another way, look into PromptSendFriendRequest in StarterGui:SetCore().
