I am making a telegram bot who will work like schedule and it is deployed on heroku. When server is restarting, chat id is clearing and the bot is not working
So I have a question. Can I somehow get chat id without user message? And is it even real?

2User must interact with bot in order to get chat id of the user – Swapnil Soni Aug 27 '21 at 09:49

You need to chat with the user (at least once) then save the chat_id for future usage, see https://stackoverflow.com/a/64681056/9095551 – Beppe C Aug 27 '21 at 11:41

Welcome! Could you add some minimal reproducible code? In that way it's easier for us to help you out. – JW Geertsma Aug 27 '21 at 12:46

you must back up those id's and your session files
the session file contains information about all your interactions with telegram (chats , massages ,....)
before server restarts , save the session files remember saving the session files and coping them again to their directory after the restart is like nothing has happend to the bot , because everything is saved into these files .
connect your bot to a database system . mysql ,..... or just save chat id (or peer id ) number (which is inside the update array ) into a file (txt , json ,...) then use them after server restarts .
if you lose the session files it's like the memory of bot is erased
