4. BotFather will reply with your bot token. It looks like: 123456789:ABCdefGHIjklMNOpqrsTUVwxyz

Save this token — you’ll use it as TELEGRAM_BOT_TOKEN when configuring the extension.

2. Get your chat ID with getUpdates

1. Open a chat with your new bot and send it any message (for example: hello).
2. In a browser, open: https://api.telegram.org/bot<YOUR_BOT_TOKEN>/getUpdates Replace <YOUR_BOT_TOKEN> with the token from BotFather.

In the JSON response, find "chat":{"id": ... }. That number is your chat ID.

If result is empty ([]), send another message to the bot and refresh the URL.
