Hello, I am doing some tests with this service and it caused me an error, could someone give me a hand, what am I doing wrong? :frowning:

local HttpService = game:GetService('HttpService')
local URL = 'https://pokeapi.co/api/v2/pokemon/1'

function httpRequest(getAsync, service, urlLink)
	local success, errorMessage = pcall(getAsync, urlLink)
	
	if not success then
		warn('Something went wrong!')
		return warn(errorMessage)
	else
		warn('Everything works perfect!')
		local decodedTable = service:JSONDecode(success)
		print(decodedTable)
	end
end

httpRequest(HttpService:GetAsync(), HttpService, URL)

Here is my version of your code

local HttpService = game:GetService('HttpService')
local URL = 'https://pokeapi.co/api/v2/pokemon/1'


function httpRequest()
	local response
	local data
	local success, errorMessage = pcall(function()
		response = HttpService:GetAsync(URL)
		data = HttpService:JSONDecode(response)
	end)
	
	if not success then
		warn('Something went wrong!')
		return warn(errorMessage)
	else
		warn('Everything works perfect!')
		print(data)
	end
end

httpRequest()

The problem is quite simple.

You can’t pass HttpService:GetAsync() through a function like this. You’re passing the result, not the actual method, which doesn’t work. It’s also completely pointless. In reality, you’re looking to do this:

local HttpService = game:GetService("HttpService")
...
local success, errorMessage = pcall(HttpService.GetAsync, HttpService, urlLink)

This calls the method inside of the pcall as it should. Note that you have to pass HttpService as a parameter, because you are calling the method with a dot . rather than a colon :.

the p call has to be in a function otherwise it wont work

Another reason why it may not work is because Roblox recently restricted some of the ports for HttpService.

Here’s the full announcement:

This is using the default :443 port which is allowed.
