python-telegram

Python API for the tdlib library. It helps you build your own Telegram clients.

tdlib connects to Telegram over MTProto, the same protocol the official apps use. This library signs in as a full Telegram account with a phone number, and it can do what a regular client can do.

It is not a wrapper around the HTTP Bot API. If you only need a bot, python-telegram-bot is a better fit. You can still sign in as a bot here by passing bot_token instead of phone.

Installation

This library requires Python 3.10+. Windows is not supported.

pip install python-telegram

See documentation for more details.

tdlib

Four wheels bundle a tdlib binary. Each one works on Python 3.10 through 3.14:

Those binaries link OpenSSL and zlib statically, so they need nothing from the system.

Anywhere else, pip installs the source distribution, which carries no binary. On musl, on 32-bit ARM, or with an older glibc, compile tdlib yourself.

python-telegram looks for the library in this order, and logs which one it used:

1. the library_path argument
2. the PYTHON_TELEGRAM_TDLIB_PATH environment variable
3. a system-wide tdjson
4. the bundled binary

A system-wide tdlib therefore wins over the bundled one. To point at a specific build, pass its path. The file is called libtdjson.so on Linux and libtdjson.dylib on macOS:

tg = Telegram(
    # ...
    library_path="/usr/local/lib/libtdjson.so",
)

If nothing can be found, TDJson() raises TDLibNotFoundError, an OSError subclass whose message names the platform, the paths tried and the overrides.

Docker

This library has a docker image:

docker run -i -t --rm \
            -v /tmp/docker-python-telegram/:/tmp/ \
            akhmetov/python-telegram \
            python3 /app/examples/send_message.py $API_ID $API_HASH $PHONE $CHAT_ID $TEXT

How to use the library

First, register a new Telegram application to get your api_id and api_hash. Check out the tutorial for more details.

Basic example:

from telegram.client import Telegram
from telegram.text import Spoiler

tg = Telegram(
    api_id=123456,
    api_hash="api_hash",
    phone="+31611111111",  # you can pass 'bot_token' instead
    database_encryption_key="changekey123",
    files_directory="/tmp/.tdlib_files/",
)
tg.login()

# The chat must be in the tdlib database before you can send a message to it.
# `get_chats` loads up to `limit` chats from the main chat list.
result = tg.get_chats(limit=100)
result.wait()

chat_id = 123456789
result = tg.send_message(chat_id, Spoiler("Hello world!"))

# `tdlib` is asynchronous, so `python-telegram` always returns an `AsyncResult` object.
# You can receive a result with the `wait` method of this object.
result.wait()
print(result.update)

tg.stop()  # You must call `stop` at the end of the script.

You can also use call_method to call any tdlib method:

tg.call_method("getUser", params={"user_id": user_id})

More examples can be found in the /examples/ directory.
