10. The Telegram Bot
1. The bot uses the Telegram Bot API with the "long
pooling method" for managing the bot interactions
with the backend Spring Boot application.
2. The Telegram Bot
• Is bootstrapped with the Spring Boot application
on the same main entry point class.
• A default session with the Telegram platform is
created.
• A controller that implements the Telegram Bot
functionality is registered as a bot. It uses the
Telegram Bot Token you got from the Telegram
platform.
• The controller makes REST calls to remote API
implementation.
