Demo: @my_id_bot in Telegram.

This is a simple bot written with aiogram 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);
• Sticker ID (they can be re-used with any bot);
• Group to supergroup migrate information (both old and new ID).

• Python 3.7 and above;
• Linux (should work on Windows, but not tested);
• Systemd init system (not necessary).
• Docker (optional, see below).

1. Create a directory for bot: mkdir my-id-bot;
2. cd my-id-bot && python3 -m venv venv;
3. Put bot.py file to my-id-bot directory;
4. source venv/bin/python && pip install -r requirements.txt;
5. chmod +x bot.py;
6. BOT_TOKEN=12345:abcxyz ENABLE_STATS=0 ./bot.py

If you want systemd support for autostart and other tasks: open my-id-bot.service file, change relevant options to match yours, enter correct token.
Now copy that file to /etc/systemd/system enable it with systemctl enable my-id-bot.service and run it: systemctl restart my-id-bot.service. Easy!

Alternatively, you can use Docker (experimental):
Build image: docker build -t my-id-bot-image .
Run container: docker run -e BOT_TOKEN=12345:abcxyz -e ENABLE_STATS=0 -v /path/to/logs/on/host:/logs --name my-id-bot -d --rm my-id-bot-image.
Or use Docker Compose as docker-compose up -d.
