This class provides access to the full Telegram Bot API. All methods of the API have an equivalent on this class, with the most important parameters pulled up into the function signature, and the other parameters captured by an object.

When your bot receives a message, Telegram sends an update object to your bot. The update contains information about the chat, the user, and of course the message itself. There are numerous other updates, too: https://core.telegram.org/bots/api#update

This object represents a file ready to be downloaded. The file can be downloaded via the link https://api.telegram.org/file/bot/<file_path>. It is guaranteed that the link will be valid for at least 1 hour. When the link expires, a new one can be requested by calling getFile.

Represents the raw Telegram Bot API with all methods specified 1:1 as documented on the website (https://core.telegram.org/bots/api).

API call transformers are functions that can access and modify the method and payload of an API call on the fly. This can be useful if you want to implement rate limiting or other things against the Telegram Bot API.
