Telegram: 7. Polling Setup

The following tutorial shows how to configure PollingTelegramInterface.

See PollingTelegramInterface for more information.

# installing dependencies
%pip install -q dff[telegram]

Note: you may need to restart the kernel to use updated packages.

import os

from dff.messengers.telegram.interface import PollingTelegramInterface
from dff.pipeline import Pipeline

from dff.utils.testing.common import is_interactive_mode
from dff.utils.testing.toy_script import TOY_SCRIPT_ARGS, HAPPY_PATH
from telebot.util import update_types

PollingTelegramInterface can be configured with the same parameters that are used in the pytelegrambotapi library, specifically:

• interval - time between calls to the API.

• allowed updates - updates that should be fetched.

• timeout - general timeout.

• long polling timeout - timeout for polling.

interface = PollingTelegramInterface(
    token=os.environ["TG_BOT_TOKEN"],
    interval=2,
    allowed_updates=update_types,
    timeout=30,
    long_polling_timeout=30,
)


# testing
happy_path = HAPPY_PATH

pipeline = Pipeline.from_script(
    *TOY_SCRIPT_ARGS,
    messenger_interface=interface,
    # The interface can be passed as a pipeline argument
)


def main():
    pipeline.run()


if __name__ == "__main__" and is_interactive_mode():
    # prevent run during doc building
    main()
