I’m stuck trying to send messages with the python-telegram-bot library. My goal is to send a message without waiting for user input. Here’s what I’ve tried:

def send_msg(context):
    context.bot.send_message(chat_id=GROUP_CHAT_ID, text='Hello, world!')


def setup():
    bot_updater = Updater(BOT_TOKEN)
    dispatcher = bot_updater.dispatcher

    msg_handler = MessageHandler(Filters.text & (~Filters.command), send_msg)
    dispatcher.add_handler(msg_handler)

    bot_updater.start_polling()
    bot_updater.idle()


setup()

I got the GROUP_CHAT_ID from the Telegram API. The code runs without errors, but no message is sent. What am I doing wrong? Any help would be awesome!

I’ve encountered similar issues when working with python-telegram-bot. The problem lies in your setup - it’s configured to respond to incoming messages rather than send them proactively. To send a message without waiting for user input, you can simplify your code significantly:

from telegram import Bot

bot = Bot(token=BOT_TOKEN)
bot.send_message(chat_id=GROUP_CHAT_ID, text='Hello, world!')

This approach directly creates a Bot instance and sends the message. It’s more straightforward for your use case. Remember to handle potential exceptions, as network issues or incorrect tokens can cause errors. Also, ensure your BOT_TOKEN and GROUP_CHAT_ID are correct. If you’re still having trouble, double-check your bot’s permissions in the group chat.

Hey there! I’ve been using python-telegram-bot for a while now, and I think I see where you’re running into trouble. Your code is set up to respond to incoming messages, but it looks like you want to send a message proactively.

Try this approach instead:

from telegram.ext import Updater


def send_message():
    updater = Updater(BOT_TOKEN, use_context=True)
    updater.bot.send_message(chat_id=GROUP_CHAT_ID, text='Hello, world!')

send_message()

This should send the message right away without waiting for any input. Just make sure your BOT_TOKEN and GROUP_CHAT_ID are correct. Also, remember to handle any potential exceptions that might occur when sending messages.

Hope this helps you out! Let me know if you need any more clarification.

updater = Updater(BOT_TOKEN, use_context=True)
updater.bot.send_message(chat_id=GROUP_CHAT_ID, text='Hello, world!')

this should fire off ur msg right away. lmk if it works!
