Add clickable buttons to telegram-bot – Telegram API

I’m developing a simple telegram bot with node.js telegram-bot.
https://github.com/yagop/node-telegram-bot-api
For now I want user to stop typing messages (with letters), just pressing one of a few buttons. And when he clicks on the button, his telegram’s client has to send back to my bot another message (something like “clicked yes” or “clicked no”).
I’ve found that it can be made with 

var options = {
      reply_markup: JSON.stringify({
        inline_keyboard: [
          [{ text: 'Some button text 1', callback_data: '1' }],
          [{ text: 'Some button text 2', callback_data: '2' }],
          [{ text: 'Some button text 3', callback_data: '3' }]
        ]
      })
    };
bot.sendMessage(msg.chat.id, "answer.", option);

So user receives 3 kind of messages, and when he clicks them, he doesn’t send me back anything.
I need another type of buttons (which will be in the bottom of client’s app).

    You need to listen for the callback_query .. As outlined : 

    bot.on('callback_query', function onCallbackQuery(callbackQuery) {
  const action = callbackQuery.data;
  const msg = callbackQuery.message;
  const opts = {
    chat_id: msg.chat.id,
    message_id: msg.message_id,
  };
  let text;

  if (action === '1') {
    text = 'You hit button 1';
  }

  bot.editMessageText(text, opts);
});

    More info can be found in the library itself. : https://github.com/yagop/node-telegram-bot-api/blob/0174b875ff69f6750fc80a049315c9a0d7a5e471/examples/polling.js#L78

    Some further reading indicates : https://core.telegram.org/bots/api#callbackquery

    TelegramBot emits callback_query when receives a Callback Query

    This relates to this documentation here : https://core.telegram.org/bots/api#callbackquery

    If the button was attached to a message sent via the bot (in inline mode), the field inline_message_id will be present.

    Exactly one of the fields data or game_short_name will be present.

    You are using inline keyboard, instead you can try reply keyboard markup which appears in the bottom of telegram screen as you said.

    It is implemented easily and you can find some useful information about it here and here.

    I’ve used telegraf library while working on telegram-bot, most of the libraries are same so you can consider it for reference.

    You will get callback_data as an input when user click on the button

    await bot.telegram.sendMessage(ctx.chat.id, "Please click on button below.", {
    reply_markup: {
        inline_keyboard: [
            [   
                {
                    text: "Yes",
                    callback_data: "btn_yes"
                },
                {
                    text: "No",
                    callback_data: "btn_no"
                },
               
            ]
        ]
    }
});
