How to Capture ForceReply Responses in a Python Telegram Bot

I’m creating a Telegram bot using python-telegram-bot and I need to catch the reply from a ForceReply message. The idea is simple:

  1. The user sends the /start command
  2. The bot replies with a message prompting a response via ForceReply
  3. The user answers
  4. The bot processes that reply

I’ve tried something like this:

reply_text = "Hello! Please reply to proceed with your registration."

def initiate_handler(update: Update, context: CallbackContext):
    chat_identifier = update.message.chat.id
    print(update.message.from_user.username)
    context.bot.send_message(chat_id=chat_identifier, text=reply_text, reply_markup=ForceReply())

Based on my experience, using a ConversationHandler can help structure your implementation to capture ForceReply responses effectively. Instead of expecting the reply in the same function that sends out the ForceReply, setting up a separate handler for the next state simplifies maintaining context across messages. The ConversationHandler lets you define states and map incoming messages to specific functions, creating a robust framework even if a user’s response deviates or times out. This modular approach generally reduces errors and keeps your code cleaner and more maintainable.

hey i solved it by checking update.message.reply_to_message id match, so only response to your force reply gets processed. not the fanciest way but works well for basic bots

I found an alternative strategy that worked well in my project. I implemented a custom message handler to detect replies by verifying that the reply message actually refers to the original ForceReply message. My approach used the update object’s reference field to match the message IDs, ensuring that only the intended reply was processed. It took some trial and error to iron out unexpected messages, but the solution is quite robust. Using this filtering method, I was able to reliably capture the user response without much overhead.

My solution involved storing the promised message id when sending a ForceReply message. When the bot prompts the user, I save the id of the ForceReply message in an external cache associated with that chat. In the subsequent update, I check if the incoming message has a reply_to_message attribute and then compare its id with the stored id. This method allowed me to capture the intended response without adopting a full ConversationHandler. It simplifies managing state across messages while ensuring that only valid replies are processed.

hey, try comparing reply msg id with the stored id from teh forcereply. i did this in a simple bot and it captured only relevant responses. works good for small setups and keeps it straight-forwards
