Created using:

• maven
• java 17
• Spring boot
• telegram bot library for java(https://github.com/rubenlagus/TelegramBots)

Run:

1. Create bot via BotFather (t.me/BotFather)
2. Specify token and username in application.yml
3. Run Application.main()
4. Bot will be automatically registered, because it contains telegrambots-spring-boot-starter
5. Now navigate to your bot and try to send some text to the bot

Troubleshooting

If you observe issues during application start like error removing old web-hook, then make sure only one instance of bot is running, also check if you have provided good token.
