==================
_`Getting started`
==================

View the last release API documentation at: https://core.telegram.org/bots/api

------
_`API`
------

The API is exposed via the ``telegram.Bot`` class.

To generate an Access Token you have to talk to `BotFather <https://telegram.me/botfather>`_ and follow a few simple steps (described `here <https://core.telegram.org/bots#botfather>`_).

For full details see the `Bots: An introduction for developers <https://core.telegram.org/bots>`_.

To create an instance of the ``telegram.Bot``::

    >>> import telegram
    >>> bot = telegram.Bot(token='token')

To see if your credentials are successful::

    >>> print bot.getMe()
    {"first_name": "Toledo's Palace Bot", "username": "ToledosPalaceBot"}

Bots can't initiate conversations with users. A user must either add them to a group or send them a message first. People can use ``telegram.me/<bot_username>`` links or username search to find your bot.

To fetch text messages sent to your Bot::

    >>> updates = bot.getUpdates()
    >>> print [u.message.text for u in updates]

To fetch images sent to your Bot::

    >>> updates = bot.getUpdates()
    >>> print [u.message.photo for u in updates if u.message.photo]

To reply messages you'll always need the chat_id::

    >>> chat_id = bot.getUpdates()[-1].message.chat_id

To post a text message::

    >>> bot.sendMessage(chat_id=chat_id, text="I'm sorry Dave I'm afraid I can't do that.")

To post a text message with markdown::

    >>> bot.sendMessage(chat_id=chat_id, text="*bold* _italic_ [link](http://google.com).", parse_mode=telegram.ParseMode.MARKDOWN)

To post an Emoji (special thanks to `Tim Whitlock <http://apps.timwhitlock.info/emoji/tables/unicode>`_)::

    >>> bot.sendMessage(chat_id=chat_id, text=telegram.Emoji.PILE_OF_POO)

To post an image file via URL (right now only sendPhoto supports this)::

    >>> bot.sendPhoto(chat_id=chat_id, photo='https://telegram.org/img/t_logo.png')

To post a voice file::

    >>> bot.sendVoice(chat_id=chat_id, voice=open('tests/telegram.ogg', 'rb'))

To tell the user that something is happening on bot's side::

    >>> bot.sendChatAction(chat_id=chat_id, action=telegram.ChatAction.TYPING)

To create `Custom Keyboards <https://core.telegram.org/bots#keyboards>`_::

    >>> custom_keyboard = [[ telegram.Emoji.THUMBS_UP_SIGN, telegram.Emoji.THUMBS_DOWN_SIGN ]]
    >>> reply_markup = telegram.ReplyKeyboardMarkup(custom_keyboard)
    >>> bot.sendMessage(chat_id=chat_id, text="Stay here, I'll be back.", reply_markup=reply_markup)

To hide `Custom Keyboards <https://core.telegram.org/bots#keyboards>`_::

    >>> reply_markup = telegram.ReplyKeyboardHide()
    >>> bot.sendMessage(chat_id=chat_id, text="I'm back.", reply_markup=reply_markup)

To download a file (you will need its file_id)::

    >>> file_id = message.voice.file_id
    >>> newFile = bot.getFile(file_id)
    >>> newFile.download('voice.ogg')

There are many more API methods, to read the full API documentation::

    $ pydoc telegram.Bot

-----------
_`Logging`
-----------

You can get logs in your main application by calling `logging` and setting the log level you want::

    >>> import logging
    >>> logger = logging.getLogger()
    >>> logger.setLevel(logging.INFO)

If you want DEBUG logs instead::

    >>> logger.setLevel(logging.DEBUG)

-----------
_`Examples`
-----------

Here follows some examples to help you to get your own Bot up to speed:

- `echobot <https://github.com/leandrotoledo/python-telegram-bot/blob/master/examples/echobot.py>`_ replies back messages.

- `roboed <https://github.com/leandrotoledo/python-telegram-bot/blob/master/examples/roboed.py>`_ talks to `Robô Ed <http://www.ed.conpet.gov.br/br/converse.php>`_.

- `Simple-Echo-Telegram-Bot <https://github.com/sooyhwang/Simple-Echo-Telegram-Bot>`_ simple Python Telegram bot that echoes your input with Flask microframework, setWebhook method, and Google App Engine (optional) - by @sooyhwang.

- `DevOps Reaction Bot <https://github.com/leandrotoledo/gae-devops-reaction-telegram-bot>`_ sends latest or random posts from `DevOps Reaction <http://devopsreactions.tumblr.com/>`_. Running on `Google App Engine <https://cloud.google.com/appengine>`_ (billing has to be enabled for fully Socket API support).
