Telegram Bot on ruby

apt-get install ruby gem ruby-dev make
gem install telegram-bot-ruby

Теперь необходимо получить токен для бота.
Заходим в Telegram, добавляем бота @BotFather, и создаем бота:

Telegram Bot
Telegram Bot

So, let’s write to out bot and get updates

curl -s -X POST https://api.telegram.org/botNNNNN:NZNZNNZNZNZNNZNZ/getUpdates

And we have:

# encoding: utf-8
require 'telegram/bot'
#require_relative 'getimg'

#inputMess = ARGV[0]
puts "fff"
Telegram::Bot::Client.run(token) do |bot|
    #  bot.listen do |chat|
    bot.api.sendMessage(chat_id: "", text: "Hello")
