TelegramOperator
================

Use the :class:`~airflow.providers.telegram.operators.telegram.TelegramOperator`
to send message to a `Telegram <https://telegram.org/>`__ group or a specific chat.


Using the Operator
^^^^^^^^^^^^^^^^^^

Use the ``telegram_conn_id`` argument to connect to Telegram client where
the connection metadata is structured as follows:

.. list-table:: Telegram Connection Metadata
   :widths: 25 25
   :header-rows: 1

   * - Parameter
     - Input
   * - Password: string
     - Telegram Bot API Token
   * - Host: string
     - Chat ID of the Telegram group/chat
   * - Connection Type: string
     - http as connection type

An example usage of the TelegramOperator is as follows:

.. exampleinclude:: /../../airflow/providers/telegram/example_dags/example_telegram.py
    :language: python
    :start-after: [START howto_operator_telegram]
    :end-before: [END howto_operator_telegram]

.. note::

  Parameters that can be passed onto the operator will be given priority over the parameters already given
  in the Airflow connection metadata (such as ``Host``, ``Password`` and so forth).
