Once a project is set up, you will still have to follow a few steps before you can actually use Pyrogram to make API calls. This section provides all the information you need in order to authorize yourself as user or bot.
In order to use the API, Telegram requires that users be authorized via their phone numbers.
Pyrogram automatically manages this process, all you need to do is create an instance of the
Client class by passing to it a
session_name of your choice (e.g.: “my_account”) and call
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 in your devices that are already authorized or via SMS:
Enter phone number: +39********** Is "+39**********" correct? (y/n): y Enter phone code: 32768 Logged in successfully as Dan
After successfully authorizing yourself, a new file called
my_account.session will be created allowing Pyrogram to
execute 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.
*.session file is personal and must be kept secret.
The code above does nothing except asking for credentials and keeping the client online, hit CTRL+C now to stop your application and keep reading.
Bots are a special kind of users that are authorized via their tokens (instead of phone numbers), which are created by the Bot Father. Bot tokens replace the users’ phone numbers only — you still need to configure a Telegram API key with Pyrogram, even when using bots.
The authorization process is automatically managed. All you need to do is choose a
session_name (can be anything,
usually your bot username) and pass your bot token using the
bot_token parameter. The session file will be named
after the session name, which will be
my_bot.session for the example below.
from pyrogram import Client app = Client( "my_bot", bot_token="123456:ABC-DEF1234ghIkl-zyx57W2v1u123ew11" ) app.run()
