Sending a notification message to Telegram using its HTTP API via cURL
  1. Create a bot
  2. Get the bot's API token from @BotFather
  3. Add your bot to the chat you'll be sending messages to
  4. Get the ID of the chat
    a. Fetch bot updates and look for the chat id:
    curl https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/getUpdates | jq '.result[0].message.chat.id'
    
    b. OR, run bot.rb and @-mention your bot in the chat. The chat id will appear in bot.rb's output.
    The bot may need temporary message access: @BotFather > Bot Settings > Group Privacy > Turn off
  5. Send a message using the HTTP API: https://core.telegram.org/bots/api#sendmessage
    curl -X POST \
         -H 'Content-Type: application/json' \
         -d '{"chat_id": "123456789", "text": "This is a test from curl", "disable_notification": true}' \
         https://api.telegram.org/bot$TELEGRAM_BOT_TOKEN/sendMessage
# Use this script to test that your Telegram bot works.
