Bot to get users/chats IDs in Telegram

Give it a try: @my_id_bot.

This is a simple bot written with aiogram 3.x framework to show some IDs, like:

Your user ID (when asked in inline mode or in private chat with any message);
Group/supergroup ID (when added to that group or with /id command);
Channel ID (when message forwarded from channel to one-to-one chat with bot);
Supergroup ID (when message forwarded from anonymous group admin);
Topic ID for forum supergroups;
Sticker ID (they can be re-used with any bot);
Group to supergroup migrate information (both old and new ID).

Requirements:

Python 3.11 and newer;
Linux (should work on Windows, but not tested);
Systemd init system (optional).
Docker (optional).

Installation:

Just to test (not recommended)

Clone this repo;
cd to cloned directory and initialize Python virtual environment (venv);
Activate the venv and install all dependencies from requirements.txt file;
Copy env_example to .env (with the leading dot), open .env and edit the variables;
In the activated venv: python -m bot

Systemd

Perform steps 1-4 from "just to test" option above;
Copy my-id-bot.example.service to my-id-bot.service (or whatever your prefer), open it and edit WorkingDirectory and ExecStart directives;
Copy (or symlink) that service file to /etc/systemd/system/ directory;
Enable your service sudo systemctl enable my-id-bot --now;
Check that service is running: systemctcl status my-id-bot (can be used without root privileges).

Docker + Docker Compose

Get docker-compose.example.yml file and rename it as docker-compose.yml;
Get env_example file, rename it as .env (with the leading dot), open it and edit the variables;
Run the bot: docker compose up -d;
Check that container is up and running: docker compose ps
