How to understand where a variable comes from in a post request?

Question

Python

I need to log in to the site in order to get data from there.
And there you need to pass authorization twice. The first time everything goes well, but the second time this execution appears, which is different all the time. I want to understand how it is generated. Where can you watch it?

Thank you all in advance for your replies!

Answer 1

Go to the Initiator tab and see what JS functions are processed both for the login method itself and before it. Most likely, at some point, the server sends a key to the client, which is used for login, but is not stored anywhere.
