How to implement Telegram WebHook on heroku?

Question

Digital certificates

I have a telegram bot hosted on heroku. Running heroku with the free package won't let my app run 24/7 in worker mode, so we can't afford polling. The solution could be WebHook, but it requires a TLS certificate. where to get it or make it work? I've read the node-telegram-bot-api and heroku documentation on this topic, but I didn't understand anything.

Answer 1

Obviously, you need to select the Hobby package or higher, which ensures that the application does not fall asleep and also solves the problem with the certificate.
