Telepot - read text of a sent message

Question

I use telepot python library with my bot, in python 3.5. I want to read the text of a message that is already in a chat, knowing the id of the telegram chat and the id of the message. How can I do?

Answer 1

The telepot library is a wrapper around the Telegram Bot HTTP API and unfortunately the API doesn't have such method available at the moment. (see here for full list of all available methods). Additionally, telepot is no longer actively maintained.

Nonetheless, you can directly make requests to the telegram servers (skipping the intermediary HTTP API) by using mtproto protocol based libraries (such as Telethon, Pyrogram, MadelineProto, etc..) instead.

Here is an example using Telethon to give you an idea:

from telethon import TelegramClient

API_ID = ...
API_HASH = ' ... '

BOT_TOKEN = ' ... '

client = TelegramClient('bot_session', API_ID, API_HASH).start(bot_token = BOT_TOKEN)

async def main():
    message = await client.get_messages(
        -10000000000, # channel ID
        ids=3 # message ID
    )
    print("MESSAGE:\n---\n")
    print(message.text)

client.start()
client.loop.run_until_complete(main())

[user@pc ~]$ python main.py
MESSAGE:
---

test message

You can get values for API_ID and API_HASH by creating an application over my.telegram.org (see this page for more detailed instruction)
