Question

Bots

I lost access to my telegram, the sim card is not recoverable, I need to restore contacts, one of them launched my telegram bot. How can I use my bot's api to get his contact. Please tell me it's very necessary.

Answer 1

The list of users of your bot can be obtained if you saved them yourself, to a file, to the database ...
If you did not save the list of users, then no api will help you.

Answer 2

It is necessary to use the base, otherwise nothing.
