Configuration

Environment Variables

You need to set up the following environment variable:

TELEGRAM_BOT_TOKEN=your_bot_token

You can get your bot token by talking to @BotFather on Telegram and creating a new bot.

Creating a new bot

Use the /newbot command to create a new bot. @BotFather will ask you for a name and username, then generate an authentication token for your new bot.

The name of your bot is displayed in contact details and elsewhere.

The username is a short name, used in search, mentions and t.me links. Usernames are 5-32 characters long and not case sensitive – but may only include Latin characters, numbers, and underscores. Your bot's username must end in 'bot', like 'tetris_bot' or 'TetrisBot'.

The token is a string, like 110201543:AAHdqTcvCH1vGWJxfSeofSAs0K5PALDsaw, which is required to authorize the bot and send requests to the Bot API. Keep your token secure and store it safely, it can be used by anyone to control your bot.

Unlike the bot's name, the username cannot be changed later – so choose it carefully. When sending a request to api.telegram.org, remember to prefix the word 'bot' to your token.
