Pyrogram is a framework written from the ground up that acts as a fully-fledged Telegram client based on the MTProto
|
|
|
|
|
API. This means that Pyrogram is able to execute any official client and bot API action and more. This page will
|
|
|
|
|
therefore show you why Pyrogram might be a better choice for your project by comparing the two APIs, but first, let's
|
|
|
|
|
make it clear what actually is the MTProto and the Bot API.

What is the MTProto API?

`MTProto`_, took alone, is the name of the custom-made, open and encrypted communication protocol created by Telegram
|
|
|
|
|
itself --- it's the only protocol used to exchange information between a client and the actual Telegram servers.

The MTProto API on the other hand, is what people for convenience call the main Telegram API in order to distinguish it
|
|
|
|
|
from the Bot API. The main Telegram API is able to authorize both users and bots and is built on top of the MTProto
|
|
|
|
|
encryption protocol by means of `binary data serialized`_ in a specific way, as described by the `TL language`_, and
|
|
|
|
|
delivered using UDP, TCP or even HTTP as transport-layer protocol. Clients that make use of Telegram's main API, such as
|
|
|
|
|
Pyrogram, implement all these details.

What is the Bot API?

The `Bot API`_ is an HTTP(S) interface for building normal bots using a sub-set of the main Telegram API. Bots are
|
|
|
|
|
special accounts that are authorized via tokens instead of phone numbers. The Bot API is built yet again on top of the
|
|
|
|
|
main Telegram API, but runs on an intermediate server application that in turn communicates with the actual Telegram
|
|
|
|
|
servers using MTProto.

Advantages of the MTProto API

Here is a non-exhaustive list of all the advantages in using MTProto-based libraries -- such as Pyrogram -- instead of
|
|
|
|
|
the official HTTP Bot API. Using Pyrogram you can:
