Telethon

.. epigraph::

⭐️ Thanks everyone who has starred the project, it means a lot!

|logo| Telethon is an asyncio_ Python 3 MTProto_ library to interact with Telegram_'s API as a user or through a bot account (bot API alternative).

.. important::

If you have code using Telethon before its 1.0 version, you must
read `Compatibility and Convenience`_ to learn how to migrate.
As with any third-party library for Telegram, be careful not to
break `Telegram's ToS`_ or `Telegram can ban the account`_.

What is this?

Telegram is a popular messaging application. This library is meant to make it easy for you to write Python programs that can interact with Telegram. Think of it as a wrapper that has already done the heavy job for you, so you can focus on developing an application.

Installing

.. code-block:: sh

pip3 install telethon

Creating a client

.. code-block:: python

from telethon import TelegramClient, events, sync

# These example values won't work. You must get your own api_id and
# api_hash from https://my.telegram.org, under API Development.
api_id = 12345
api_hash = '0123456789abcdef0123456789abcdef'

client = TelegramClient('session_name', api_id, api_hash)
client.start()

Doing stuff

.. code-block:: python

print(client.get_me().stringify())

client.send_message('username', 'Hello! Talking to you from Telethon')
client.send_file('username', '/home/myself/Pictures/holidays.jpg')

client.download_profile_photo('me')
messages = client.get_messages('username')
messages[0].download_media()

@client.on(events.NewMessage(pattern='(?i)hi|hello'))
async def handler(event):
    await event.respond('Hey!')
