Get group rank from offline player

[Executive_II (Executive)]

Hello, I’ve been looking everywhere to see how I would be able to get the rank from an offline player, using UserID. I’ve seen mentions of using GetGroupsAsync which provides a table of all the user’s groups. Great, now I have to search through to find my group and the rank associated with it. This is where I am stuck at, I am not exactly sure how I would go about doing this.

local Group = 0 -- My group ID, ofc
local function checkRank(userId)
	
	local success, rank = pcall(function()
		local UserGroups = game:GetService("GroupService"):GetGroupsAsync(userId)

		local UserGroupData = table.find(UserGroups, Group)
		if UserGroupData ~= nil then
			local rank = table.find(UserGroupData, "rank")
			-- To find the rank value here..?
		end
	end)

	if success then
		return rank
	else
		warn("Failed to check rank for UserID:", userId, " issue: "..rank)
	end
end

Hopefully, someone can provide some helpful information on finding the group rank through the GetGroupsAsync function

pretty sure GetGroupsAsync returns a list of tables, so you couldnt just use table.find (which only works on lists, not tables).
you may have to do smth like

function FindTableInListByKey(List, KeyName, KeyValue) --list is UserGroups, keyname is 'Id' (make sure its a string), keyvalue is your groups id
    for _,table in iparis(List) do
        if table[KeyName] == KeyValue then
            return table
        end
    end
    return nil
end

to find UserGroupData, then do UserGroupData['Rank'] for the numerical rank (ie 255) or UserGroupData['Role'] for the rank name (ie Owner)

i havent tested anything ive said yet and have based all my info off the roblox wiki page, so be warned.

I see, I’ll go ahead and test to see if this can work, thank you in advance.

I found the solution to this problem, after combining things together and such. Here is my final result:

local function checkRank(userId, group)

		local success, rank = pcall(function()
			local UserGroups = game:GetService("GroupService"):GetGroupsAsync(userId)

			for _,v in ipairs(UserGroups) do
				if v.Id == group then
					return v.Rank 
				end
			end
		end)

		if success then
			return rank
		else
			warn("Failed to check rank for UserID:", userId, " issue: "..rank)
		end
	end
