I just finished the amazing promote and demote tutorial and it all worked super slick and I’m very thankful to Cookie for making such a great resource. I was wondering how I could go about having a command that works along the lines of: “!rank Name RankID”. I’m presuming I’d need to edit code both in editor and on the repo. Does anyone know how I can do this? Thanks!

Actually, we don’t need to edit the repo.
We need to edit the code within roblox.
We already have the /group/rank/ endpoint.
You can go to, BaseURl/docs to see how that endpoint works.
If you need help scripting the part within roblox, let me know.
It would be great if you could advise me - I’m trying to learn Lua at the moment however I’m struggling with this bit. How could I go about scripting it? I see where I have to put it I think I’m just not sure how. Thanks!
Send me the main script within roblox please.
local HttpService = game:GetService("HttpService")
local ReplicatedStorage = game.ReplicatedStorage
local AppUrl = script.AppUrl.Value
local ApiKey = script.ApiKey.Value
local Groupid = script.GroupId.Value
local MinRank = script.MinRank.Value
local prefix = "!"
local function FindPlr(plr)
local foundPlr = nil
local plrs = game.Players:GetPlayers()
for i = 1, #plrs do
local current = plrs[i]
if string.lower(current.Name):sub(1, #plr) == string.lower(plr) then
foundPlr = current.Name
break
end
end
return foundPlr
end
game.Players.PlayerAdded:Connect(function(player)
player.Chatted:Connect(function(msg)
if player:GetRankInGroup(Groupid) >= 2 then
local LowerCaseMessage = string.lower(msg)
if string.find(LowerCaseMessage, "!promote") then
local SplitMessage = string.split(msg, " ")
local full_player = FindPlr(SplitMessage[2])
if full_player == nil then
local playerInstance = game.Players:FindFirstChild(player.Name)
game.ReplicatedStorage.Notify:FireClient(playerInstance, "Uh-Oh","We couldn't find the player you wanted to promote!")
else
local playerInstance = game.Players:FindFirstChild(player.Name)
game.ReplicatedStorage.Notify:FireClient(playerInstance, "Attempting.","Attempting to promote user...")
local Url = script.AppUrl.Value.."group/promote?user_name="..full_player.."&key=" ..script.ApiKey.Value.."&groupid="..script.GroupId.Value
local success, response = pcall(function()
local response = HttpService:GetAsync(Url)
local data = HttpService:JSONDecode(response)
end)
if success then
game.ReplicatedStorage.Notify:FireClient(playerInstance, "Horrah!","We promoteed the user!")
else
game.ReplicatedStorage.Notify:FireClient(playerInstance, "Uh-Oh","We had problems promoting the user.")
end
end
else if string.find(LowerCaseMessage, "!demote") then
local SplitMessage = string.split(msg, " ")
local full_player = FindPlr(SplitMessage[2])
if full_player == nil then

Alright, so how do you think you would make a new command?
I’d have to create a function with the parameters username and rankId and then somehow use that to update the group rank rather than just adding 1 to the current value. At least I think that’s how it would work?
Exactly, so we need to add a new command, get the the player and to get the rank Id we want to rank, then we need to call the rank endpoint to use the bot.
Can you guide me as to the syntax for that? I’m a bit lost.
I’m making the script right now.
Can you send me your “api link” please, no Api Key please.
https://roblox-ranking-lapd.herokuapp.com/ - is this what you mean?

Thanks a ton by the way! You’ve been the best help.
If you visit the docs endpoint your will get some documentation on the api: FastAPI - Swagger UI (roblox-ranking-lapd.herokuapp.com)
Ahh I see! Man you are a legend. 
Example of docs here:
Just finishing the script now.
I will add tags so you understand.
Try this new script:

local current = plrs[i]
if string.lower(current.Name):sub(1, #plr) == string.lower(plr) then
foundPlr = current.Name
break
end
end
return foundPlr
end
game.Players.PlayerAdded:Connect(function(player)
player.Chatted:Connect(function(msg)
if player:GetRankInGroup(Groupid) >= 2 then

game.ReplicatedStorage.Notify:FireClient(playerInstance, "Uh-Oh","We couldn't find the player you wanted to promote!")

If it works please mark this solution!
Happy new year,
Hey! It’s me on a new account as the old one said I’ve reached the maximum amount of replies for the first day and to wait 9 hours. (Hence the msg, sorry!) Basically, it says “Attempting to demote user” and then nothing happens. Do you know what could have caused this - thanks so much!
