I'm trying to create a telegram bot just by using the API and no external packages. I've done creating basic functions and my bot is able to send text messages.
I just want to know how to use ReplyKeyboardMarkup. as the documentation mentioned I should use some parameters but I don't know how to use them or if I should send them in a request.
Could someone please tell me what exactly should I do to use this API stuff in my code either than using external packages such as telebot.
