Telethon API

This documentation was generated straight from the scheme.tl provided by Telegram. However, there is no official documentation per se on what the methods, constructors and types mean. Nevertheless, this page aims to provide easy access to all the available methods, their definition and parameters.

Please note that when you see this:

---functions---
users.getUsers#0d91a548 id:Vector<InputUser> = Vector<User>

This is not Python code. It's the "TL definition". It's an easy-to-read line that gives a quick overview on the parameters and its result. You don't need to worry about this. See here for more details on it.

Methods

Currently there are {method_count} methods available for the layer {layer}. The complete list can be seen here.

Methods, also known as requests, are used to interact with the Telegram API itself and are invoked through client(Request(...)). Only these can be used like that! You cannot invoke types or constructors, only requests. After this, Telegram will return a result, which may be, for instance, a bunch of messages, some dialogs, users, etc.

Types

Currently there are {type_count} types. You can see the full list here.

The Telegram types are the abstract results that you receive after invoking a request. They are "abstract" because they can have multiple constructors. For instance, the abstract type User can be either UserEmpty or User. You should, most of the time, make sure you received the desired type by using the isinstance(result, Constructor) Python function. When a request needs a Telegram type as argument, you should create an instance of it by using one of its, possibly multiple, constructors.

Constructors

Currently there are {constructor_count} constructors. You can see the full list here.

Constructors are the way you can create instances of the abstract types described above, and also the instances which are actually returned from the functions although they all share a common abstract type.

Core types

Core types are types from which the rest of Telegram types build upon:

• int: The value should be an integer type, like 42. It should have 32 bits or less. You can check the bit length by calling a.bit_length(), where a is an integer variable.
• long: Different name for an integer type. The numbers given should have 64 bits or less.
• int128: Another integer type, should have 128 bits or less.
• int256: The largest integer type, allowing 256 bits or less.
• double: The value should be a floating point value, such as 123.456.
• Vector<T>: If a type T is wrapped around Vector<T>, then it means that the argument should be a list of it. For instance, a valid value for Vector<int> would be [1, 2, 3].
• string: A valid UTF-8 string should be supplied. This is right how Python strings work, no further encoding is required.
• Bool: Either True or False.
• flag: These arguments aren't actually sent but rather encoded as flags. Any truthy value (True, 7) will enable this flag, although it's recommended to use True or None to symbolize that it's not present.
• bytes: A sequence of bytes, like b'hello', should be supplied.
• date: Although this type is internally used as an int, you can pass a datetime or date object instead to work with date parameters.
  Note that the library uses the date in UTC+0, since timezone conversion is not responsibility of the library. Furthermore, this eases converting into any other timezone without the need for a middle step.
