Setup
=====
Once you successfully `installed Pyrogram`_, you will still have to follow a few steps before you can actually use
the library to make API calls. This section provides all the information you need in order to set up a project
with Pyrogram.
API Keys
--------
The very first step requires you to obtain a valid Telegram API key.
If you already have one you can skip this step, otherwise:
#. Visit https://my.telegram.org/apps and log in with your Telegram Account.
#. Fill out the form to register a new Telegram application.
#. Done. The Telegram API key consists of two parts: the **App api_id** and the **App api_hash**.
.. important:: This key should be kept secret.
Configuration
-------------
There are two ways to configure a Pyrogram application project, and you can choose the one that fits better for you:
- Create a new ``config.ini`` file at the root of your working directory, copy-paste the following and replace the
**api_id** and **api_hash** values with `your own <#api-keys>`_. This is the preferred method because allows you
to keep your credentials out of your code without having to deal with how to load them:
.. code-block:: ini
[pyrogram]
api_id = 12345
api_hash = 0123456789abcdef0123456789abcdef
- Alternatively, you can pass your API key to Pyrogram by simply using the *api_id* and *api_hash*
parameters of the Client class. This way you can have full control on how to store and load your credentials:
.. code-block:: python
from pyrogram import Client
app = Client(
"my_account",
api_id=12345,
api_hash="0123456789abcdef0123456789abcdef"
)
.. note:: The examples below assume you have created a ``config.ini`` file, thus they won't show the *api_id*
and *api_hash* parameters usage.
User Authorization
------------------
In order to use the API, Telegram requires that Users be authorized via their phone numbers.
Pyrogram automatically manages this access, all you need to do is create an instance of
the :class:`Client <pyrogram.Client>` class by passing to it a ``session_name`` of your choice
(e.g.: "my_account") and call the :meth:`run() <pyrogram.Client.run>` method:
.. code-block:: python
from pyrogram import Client
app = Client("my_account")
app.run()
This starts an interactive shell asking you to input your **phone number** (including your `Country Code`_)
and the **phone code** you will receive:
.. code::
Enter phone number: +39**********
Is "+39**********" correct? (y/n): y
Enter phone code: 32768
After successfully authorizing yourself, a new file called ``my_account.session`` will be created allowing
Pyrogram executing API calls with your identity. This file will be loaded again when you restart your app,
and as long as you keep the session alive, Pyrogram won't ask you again to enter your phone number.
.. important:: Your ``*.session`` file(s) must be kept secret.
Bot Authorization
-----------------
Being written entirely from the ground up, Pyrogram is also able to authorize Bots.
Bots are a special kind of users which also make use of MTProto, the underlying Telegram protocol.
This means that you can use Pyrogram to execute API calls with a Bot identity.
Instead of phone numbers, Bots are authorized via their tokens which are created by BotFather_:
.. code-block:: python
from pyrogram import Client
app = Client("123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11")
app.run()
That's all, no further action is needed. The session file will be named after the Bot user_id, which is
``123456.session`` for the example above.
