Using Django and Telegram bots as a notification service
Telegram
- Telegram is a messaging app. It’s simple and free. Open source
- You can use Telegram on all your devices at the same time: phones, tablets or computers.
- Multiplatform
- Send messages, photos, videos and files of any type
- Create groups for up to 200 people or channels
- Find people by their usernames
- As a result, Telegram is like SMS and email combined
What is a Telegram bot?
Bots are simply Telegram accounts operated by software – not people – and they'll often have AI features. They can do anything – teach, play, search, broadcast, remind, connect, integrate with other services, or even pass commands to the Internet of Things.

Let's start coding...

tb.send_message(settings.EDITOR_CHAT_ID, message)

Telebot daemon
