one_time_keyboard
Boolean
Optional. Requests clients to hide the keyboard as soon as it's been used. The keyboard will still be available, but clients will automatically display the usual letter-keyboard in the chat - the user can press a special button in the input field to see the custom keyboard again. Defaults to false.
Жаль, что такая функция только для нижней клавиатуры, но вдруг пригодится.
