Build Reply Keyboard

Quick Start

Use replyKeyboardMarkup { } or replyKeyboardMarkup(block). Attach via markup() or replyKeyboardMarkup { } on send actions.

message("Choose an option:")
    .replyKeyboardMarkup {
        +"Option A"
        +"Option B"
        newLine()
        "Share contact" requestContact true
        options { resizeKeyboard = true; oneTimeKeyboard = true }
    }
    .send(user, bot)

Simple Buttons

Use unary plus to add plain text buttons:

+"Button 1"
+"Button 2"
newLine()
+"Next row"

Special Buttons

Type	Syntax	Availability
Request contact	"Share contact" requestContact true	Private chats only
Request location	"Share location" requestLocation true	Private chats only
Request user	"Select user" requestUser KeyboardButtonRequestUsers(...)	Private chats only
Request chat	"Select chat" requestChat KeyboardButtonRequestChat(...)	Private chats only
Request poll	"Create poll" requestPoll KeyboardButtonPollType(...)	Private chats only
Web App	"Open app" webApp "https://..."	Private chats only

Options

Configure via options { }:

• resizeKeyboard = true — keyboard resizes to fit screen
• oneTimeKeyboard = true — keyboard hides after one use
• inputFieldPlaceholder = "Type here..." — placeholder in input field (1-64 chars)
• selective = true — show only to @mentioned users or reply target
• isPersistent = true — keyboard stays visible (for oneTimeKeyboard)

Rows

Use newLine() or br() to start a new row, same as inline keyboards.

Removing the Keyboard

When done, send a message with replyKeyboardRemove():

message("Keyboard removed")
    .replyKeyboardRemove()
    .send(user, bot)

Or replyKeyboardRemove(selective = true) for selective removal.
