MTProto vs. Bot API#
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:
