How to get a message from Telegram groups by API?

Question

I was looking for some way to listen and catch new messages provided by telegram groups.

I have not found libraries or API in order to do this in Python.

Someone having any suggestion?

Answer 1

There are two ways to achieve your goal:

Method 1:

My suggested library for python: python-telegram-bot

1. Create a bot.
2. Add the bot to the desired group as administrator.
3. Listen to messages as you normally listen in bots.

Method 2:

My suggested library for python: Telethon

1. Join the desired group as a user (not a bot).
2. Create a simple client that listens to new messages.
