Telethon is more than just another viable alternative when developing botsfor Telegram. If you haven’t decided which wrapper library for bots to useyet, using Telethon from the beginning may save you some headaches later.

- MTProto is really hard in implementation, but it's really easy to use. Basically, this lib sends serialized structures to Telegram servers (just like gRPC, but from Telegram LLC.). It looks like this: func main client:= & Telegram.
- Telegram is a cloud-based mobile and desktop messaging app with a focus on security and speed.

- HTTP Bot API vs MTProto
- Migrating from Bot API to Telethon
The Telegram Bot API, also known as HTTP Bot API and from now on referredto as simply “Bot API” is Telegram’s official way for developers to controltheir own Telegram bots. Quoting their main page:
The Bot API is an HTTP-based interface created for developers keen onbuilding bots for Telegram.

To learn how to create and set up a bot, please consult ourIntroduction to Bots and Bot FAQ.
Bot API is simply an HTTP endpoint which translates your requests to it intoMTProto calls through tdlib, their bot backend.
MTProto is Telegram’s own protocol to communicate with their API when youconnect to their servers.
Telethon is an alternative MTProto-based backend written entirely in Pythonand much easier to setup and use.
Both official applications and third-party clients (like your ownapplications) logged in as either user or bots can use MTProto tocommunicate directly with Telegram’s API (which is not the HTTP bot API).
When we talk about MTProto, we often mean “MTProto-based clients”.
MTProto clients (like Telethon) connect directly to Telegram’s servers,which means there is no HTTP connection, no “polling” or “web hooks”. Thismeans less overhead, since the protocol used between you and the serveris much more compact than HTTP requests with responses in wasteful JSON.
Since there is a direct connection to Telegram’s servers, even if theirBot API endpoint is down, you can still have connection to Telegram directly. Www malwarebytes org antimalware mac.
Using a MTProto client, you are also not limited to the public API thatthey expose, and instead, you have full control of what your bot can do.Telethon offers you all the power with often much easier usage than anyof the available Python Bot API wrappers.
If your application ever needs user features because bots cannot do certainthings, you will be able to easily login as a user and even keep your botwithout having to learn a new library.
If less overhead and full control didn’t convince you to use Telethon yet,check out the wiki page MTProto vs HTTP Bot API with a more exhaustiveand up-to-date list of differences.
It doesn’t matter if you wrote your bot with requests and you weremaking API requests manually, or if you used a wrapper library likepython-telegram-bot or pyTelegramBotAPI. It’s never too late tomigrate to Telethon!
If you were using an asynchronous library like aiohttp or a wrapper likeaiogram or dumbot, it will be even easier, because Telethon is also anasynchronous library.
Next, we will see some examples from the most popular libraries.
Let’s take their echobot2.py example and shorten it a bit:
After using Telethon:
Key differences:
- The recommended way to do it imports less things.
- All handlers trigger by default, so we need
events.StopPropagation
. - Adding handlers, responding and running is a lot less verbose.
- Telethon needs
asyncdef
andawait
. - The
bot
isn’t hidden away byUpdater
orDispatcher
.
Let’s show another echobot from their README:
Now we rewrite it to use Telethon:
Key differences:
- Instead of doing
bot.reply_to(message)
, we can doevent.reply
.Note that theevent
behaves just like theirmessage
. - Telethon also supports
func=lambdam:True
, but it’s not necessary.
From their GitHub:
After rewrite:
Key differences:
- Telethon offers convenience methods to avoid retyping
bot.send_photo(message.chat.id,..)
all the time,and instead let you typeevent.reply
. - Sending files is a lot easier. The methods for sendingphotos, documents, audios, etc. are all the same!
Showcasing their subclassing example:
After rewriting:
Key differences:
- Telethon method names are
snake_case
. - dumbot does not offer friendly methods like
update.reply
. - Telethon does not have an implicit
on_update
handler, sowe need to manually register one.
We offer two kinds of APIs for developers. The Bot API allows you to easily create programs that use Telegram messages for an interface. The Telegram API and TDLib allow you to build your own customized Telegram clients. You are welcome to use both APIs free of charge.
You can also add Telegram Widgets to your website.
Designers are welcome to create Animated Stickers or Custom Themes for Telegram.
Bot API
This API allows you to connect bots to our system. Telegram Bots are special accounts that do not require an additional phone number to set up. These accounts serve as an interface for code running somewhere on your server.
To use this, you don't need to know anything about how our MTProto encryption protocol works — our intermediary server will handle all encryption and communication with the Telegram API for you. You communicate with this server via a simple HTTPS-interface that offers a simplified version of the Telegram API.
Bot developers can also make use of our Payments API to accept payments Brave browser 80 1 4 96 inches. from Telegram users around the world.
TDLib – build your own Telegram
Even if you're looking for maximum customization, you don't have to create your app from scratch. Try our Telegram Database Library (or simply TDLib), a tool for third-party developers that makes it easy to build fast, secure and feature-rich Telegram apps.
TDLib takes care of all network implementation details, encryption and local data storage, so that you can dedicate more time to design, responsive interfaces and beautiful animations.
TDLib supports all Telegram features and makes developing Telegram apps a breeze on any platform. It can be used on Android, iOS, Windows, macOS, Linux and virtually any other system. The library is open source and compatible with virtually any programming language.
Telegram API
This API allows you to build your own customized Telegram clients. It is 100% open for all developers who wish to create Telegram applications on our platform. Feel free to study the open source code of existing Telegram applications for examples of how things work here. Don't forget to register your application in our system.
