HttpService is not allowed to access ROBLOX resources

What the message means

ServerScriptService.GroupRank:8: HttpService is not allowed to access ROBLOX resources

This is a deliberate block, not a setting you forgot. Turning on Allow HTTP Requests is still needed for any HTTP call, but it does not lift this one. If you see Http requests are not enabled first, fix that, and this message is the next thing you hit when the address is a Roblox website API.

The built-in services are also faster and have their own limits, so switching to them usually removes a whole class of rate-limit problems too.

Causes and fixes

Three things cause this error in practice. Each one below has the smallest code that triggers it, then the fix.

• Calling a roblox.com API that a Luau service already covers
• Calling Open Cloud without an API key, or on a web API address
• A proxy that forwards to roblox.com stopped working

Calling a roblox.com API that a Luau service already covers

Tutorials written for websites or bots use the public web APIs, and the same URLs get pasted into a game Script. From a game server, these are refused.

local HttpService = game:GetService("HttpService")

local GROUP_ID = 1234567

local function getRank(userId: number): number
	-- HttpService is not allowed to access ROBLOX resources
	local body = HttpService:GetAsync("https://groups.roblox.com/v2/users/" .. userId .. "/groups/roles")
	local data = HttpService:JSONDecode(body)
	for _, entry in data.data do
		if entry.group.id == GROUP_ID then
			return entry.role.rank
		end
	end
	return 0
end

print(getRank(156))

Use the Luau function for it. Group roles come from GroupService:GetRolesInGroupAsync, which Roblox now recommends over the older Player:GetRankInGroupAsync because a member can hold more than one role. It returns IsMember and a Roles list ordered from the highest role down.

local GroupService = game:GetService("GroupService")
local Players = game:GetService("Players")

local GROUP_ID = 1234567

Players.PlayerAdded:Connect(function(player: Player)
	local ok, result = pcall(function()
		return GroupService:GetRolesInGroupAsync(player.UserId, GROUP_ID)
	end)
	if not ok then
		warn("[GroupRank] could not read roles for", player.Name, result)
		return
	end
	local topRole = result.IsMember and result.Roles[1]
	player:SetAttribute("GroupRank", if topRole then topRole.Rank else 0)
	player:SetAttribute("GroupRoleId", if topRole then topRole.Id else 0)
end)

Common replacements: a name from a UserId with Players:GetNameFromUserIdAsync, display names and more with UserService:GetUserInfosByUserIdsAsync, item and game pass details with MarketplaceService:GetProductInfoAsync, ownership with MarketplaceService:UserOwnsGamePassAsync, group info with GroupService:GetGroupInfoAsync, and friends with Players:GetFriendsAsync.

Calling Open Cloud without an API key, or on a web API address

Some actions, such as changing a member's group role or reading another experience's data store, have no Luau function. Roblox supports a list of Open Cloud endpoints from HttpService, but only at apis.roblox.com/cloud/..., and only with an Open Cloud API key in an x-api-key header, which must be a Secret.

local HttpService = game:GetService("HttpService")

-- an old web API address, and the key typed into the script
local response = HttpService:RequestAsync({
	Url = "https://groups.roblox.com/v1/groups/1234567/users/156",
	Method = "PATCH",
	Headers = { ["Content-Type"] = "application/json", ["x-api-key"] = "paste-your-key-here" },
	Body = HttpService:JSONEncode({ roleId = 42 }),
})
print(response.StatusCode)

Create an Open Cloud API key in Creator Hub with permission for that endpoint, add it to the experience's Secrets (Creator Hub, your experience, Secrets), and read it with HttpService:GetSecret. Then call the Open Cloud address from the supported list.

local HttpService = game:GetService("HttpService")

local GROUP_ID = "1234567"

local function setRole(membershipId: string, roleId: string): boolean
	local headers: { [string]: Secret | string } = {
		["Content-Type"] = "application/json",
		["x-api-key"] = HttpService:GetSecret("APIKey"),
	}
	local ok, response = pcall(function()
		return HttpService:RequestAsync({
			Url = "https://apis.roblox.com/cloud/v2/groups/" .. GROUP_ID .. "/memberships/" .. membershipId,
			Method = "PATCH",
			Headers = headers,
			Body = HttpService:JSONEncode({ role = "groups/" .. GROUP_ID .. "/roles/" .. roleId }),
		})
	end)
	if not ok then
		warn("[Promote] request failed to send:", response)
		return false
	end
	return response.Success
end

print(setRole("your_membership_id", "your_role_id"))

Only x-api-key and content-type headers are allowed on these calls, and the key must come from GetSecret. Never type an API key into a script: anyone with edit access to the place can read it. Open Cloud calls from a game server have their own limit of 2,500 a minute, separate from the 500 a minute for other HTTP requests.

A proxy that forwards to roblox.com stopped working

A common workaround swaps roblox.com for a community proxy domain that forwards the request. That is not a Roblox resource, so it passes this check, but the proxy can rate-limit you, go offline or be blocked, and it sees everything you send. When it fails you get an HTTP error from the proxy instead.

local HttpService = game:GetService("HttpService")

-- works only while someone else's proxy is up and willing
local body = HttpService:GetAsync("https://users.example-proxy.com/v1/users/156")
print(HttpService:JSONDecode(body).name)

Replace proxy calls with the built-in service or an Open Cloud endpoint wherever one exists. Keep any proxy you still need behind pcall, and decide what the game does when it is down.

local Players = game:GetService("Players")

local ok, name = pcall(function()
	return Players:GetNameFromUserIdAsync(156)
end)
if ok then
	print(name)
else
	warn("[UserInfo] lookup failed:", name)
end

How to find the line that causes it

1. Click the red line in Output to open the script at the GetAsync, PostAsync or RequestAsync call.
2. Read the address it calls. Anything on a roblox.com subdomain is blocked from game servers.
3. Search your place for roblox.com with Ctrl+Shift+F (Find All) to catch the other calls before they fail too.

How the code was checked: every block marked Fixed passes Luau's strict type checker against Roblox's API definitions (luau-lsp, 5 November 2026), and every block marked Breaks compiles and fails only when it runs. The message wording was checked against the message strings in Roblox Studio itself (macOS build installed 2 November 2026), and the Open Cloud rules against the In-game HTTP requests docs page, on 5 November 2026. A type check catches misspelt APIs and wrong types, not game logic, so playtest in Studio before you publish.
