Installation

1. Clone or download the project

lol_queue_acceptor/
├── accept.py
└── launch.vbs

2. Install Python dependencies

pip install requests psutil websocket-client urllib3

tkinter and win32api come pre-installed with standard Python on Windows. If you get a win32api error run:

pip install pywin32

3. Set up ntfy on your phone

• Download the ntfy app (iOS or Android)
• Open the app and subscribe to a topic name of your choice (e.g. lol-queue-yourname)
• Make it unique so others can't accidentally subscribe to it

Usage

Option A — run directly

python accept.py

Option B — launch silently from taskbar (recommended) - WINDOWS

1. Right click Desktop → New → Shortcut
2. Set the location to:

   wscript.exe "C:\Users\YOUR_USERNAME\Desktop\lol_queue_acceptor\launch.vbs"
   

3. Name it Queue Accepter
4. Right click the shortcut → Pin to taskbar

Configuration

When you open the app you'll see the following options:

Setting	Description
Game Mode	Select ARAM or TFT — controls notification behaviour
Send phone notifications	Toggle ntfy notifications on or off
Auto-accept only	Accepts the queue but skips the notification
Ntfy Topic	Your unique ntfy topic name — must match what you subscribed to in the app

Hit Launch once League is open and you're in a queue. The app connects to the League client and listens for a queue pop. Hit Stop at any time to disconnect.

How it works

League of Legends runs a local API server (called the LCU API) on your machine while the client is open. It writes a lockfile to disk containing a port and one-time password that resets each session.

This app reads those credentials from the lockfile and opens a WebSocket connection to the LCU. When a queue pops, the LCU pushes a ready-check event in real time — the app catches it, calls the accept endpoint, and handles notifications based on your selected mode.

For ARAM champion detection, the app polls /lol-champ-select/v1/session and waits until the FINALIZATION phase when your champion and bench are assigned, then looks up champion names via Riot's Data Dragon CDN.

Troubleshooting

"Lockfile not found — is League open?" The app must be launched after League of Legends is already open. The lockfile only exists while the client is running.

Notification not received

• Double check your ntfy topic matches exactly (case-sensitive)
• Make sure your phone has the ntfy app open and is subscribed to the topic
• Check you don't have "Auto-accept only" ticked

WebSocket error

• Make sure League is open and you're logged in
• Try hitting Stop and Launch again to reconnect

pythonw not found when using launch.vbs Find your full Python path with:

where pythonw

Then update launch.vbs replacing pythonw with the full path e.g:

CreateObject("WScript.Shell").Run """C:\Users\YOUR_USERNAME\AppData\Local\Programs\Python\Python312\pythonw.exe"" ""C:\Users\YOUR_USERNAME\Desktop\lol_queue_acceptor\accept.py""", 0, False
