How to disable access to a bot other than Telegram?

Question

PHP

Hello! I am writing a bot in PHP for TELEGRAM. Let's say it's located on my path: https://domain.ru/bot.php .

QUESTION: How can I forbid everyone except the bot from entering here? so that attackers could not send their data here, and so on.

As I understand it, it is necessary to filter IP addresses and close them from everyone except TELEGRAM. But what is his IP address? Or how can it be played?

Answer 1

Generate a long random string and paste it into the filename or url. Then write hook.
https://domain.ru/long_random_string.php
https://domain.ru/long_random_string/bot.php .

Answer 2

There, where the least study will distract from their affairs. You can develop yourself much faster than a university does. And in our Soviet space, the crust is still not superfluous.
