How to get a token to get a captcha from a site?

Question

JavaScript

It is necessary to receive captcha from the site https://www.reestr-zalogov.ru in the ios application . The request for this captcha looks like this: https://www.reestr-zalogov.ru/Captcha/Generate?t=4...
where t is the token. However, it does not seem to be transmitted in clear form anywhere. How can I get it, please?
PS: apparently, the link to the captcha is valid only 1 time, after which, when you go to this URL, you see only a black square instead of the image with the captcha, that is, the token should change every time, as I understand it.

Answer 1

captcha once
but nothing prevents you from updating it,
put www.telerik.com/fiddler and see what and how it is called
PS do not joke with state sites, this is not Avito to parse ;-)
