aiogram includes Dispatcher mechanism. Dispatcher is needed for handling incoming updates from Telegram.

With dispatcher you can do:

  • Handle incoming updates;

  • Filter incoming events before it will be processed by specific handler;

  • Modify event and related data in middlewares;

  • Separate bot functionality between different handlers, modules and packages

Dispatcher is also separated into two entities - Router and Dispatcher. Dispatcher is subclass of router and should be always is root router.

Telegram supports two ways of receiving updates:

  • Webhook - you should configure your web server to receive updates from Telegram;

  • Long polling - you should request updates from Telegram.

So, you can use both of them with aiogram.
