Modifying inline button text after user input in a Telegram bot

I’m working on a Telegram bot using the telebot library, and I’m trying to update an inline button’s text after a user enters their input. I need a solution to ensure the button’s label changes accordingly.

Here’s a sample version of my code to illustrate my approach:

@bot.message_handler(commands=['start'])
def begin(message):
    keyboard = types.InlineKeyboardMarkup()
    login_btn = types.InlineKeyboardButton(text='Login', callback_data='login')
    keyboard.add(login_btn)
    bot.send_message(message.chat.id, "Main menu:", reply_markup=keyboard)


def ask_wallet(message):
    keyboard = types.InlineKeyboardMarkup()
    back_btn = types.InlineKeyboardButton(text='Back', callback_data='go_back')
    keyboard.add(back_btn)
    bot.edit_message_text(chat_id=message.chat.id, message_id=message.id,
                          text='Please enter your wallet address', reply_markup=keyboard)
    bot.register_next_step_handler(message, process_wallet)


def process_wallet(message):
    keyboard = types.InlineKeyboardMarkup()
    back_btn = types.InlineKeyboardButton(text='Back', callback_data='go_back')
    keyboard.add(back_btn)
    bot.edit_message_text(chat_id=message.chat.id, message_id=message.id,
                          text='Invalid wallet address', reply_markup=keyboard)


@bot.callback_query_handler(func=lambda call: True)
def handle_buttons(call):
    if call.data == 'login':
        ask_wallet(call.message)

How can I implement the change so that the inline button’s label updates once the user inputs text?

I managed a similar issue in one of my Telegram bot projects by implementing a state management approach. Instead of directly using register_next_step_handler, I stored user states in a dictionary so that when a user was expected to supply a wallet address, the state was updated accordingly. This allowed a general message handler to check the state and process the input. After validating the input, I updated the inline keyboard’s button text dynamically. Although it requires some additional setup, this approach results in a smoother user experience and better conversation flow.

Hey there! i had a similar problem. What worked for me was using a dict to keep track of user states. When they input the wallet, update the state and use edit_message_reply_markup to change the button text. It’s a bit tricky but works great once you get it set up. Good luck!

To update an inline button’s text after a user input in a Telegram bot, you can use a conversation-based approach rather than relying on bot.register_next_step_handler. One method involves tracking the state of each user with a dictionary, where you store their current step in the interaction. When the user provides the wallet address, check the stored state and update the button label in the edited message accordingly. This method keeps the inline keyboard persistent while dynamically changing its content based on user input.
