How to get information from the site?

Question

Parsing

I'm making a bot to make my job easier. I ran into a problem that I can’t figure out how to make it so that I can transfer information to the site, “click” on the button and get information from the next page. Moreover, it is necessary to do it in such a way that the process is executed inside the program, selenium will not work.

https://cerberus.vetrf.ru/cerberus/actualObject/pu... page where you need to enter a special key

after entering the key,
we will get to the data page and you will need to pull out one line with the words "Confirmed", if not, then there will be "Not Confirmed".
