Parsing post request and response in Chrome?

Question

Google Chrome

It is necessary to automatically collect data from the site. Data submitted by contact information about the service points. The page contains a drop-down list of regions, when one of them is selected, a post-request is executed, as I understand it, and the contact information of the nearest service points is loaded.
How can I trace the sent post request with the specified parameter and the response received?
I used the Chrome developer tools. In the Network tab, you can see that the page is sent by a post request, but I still didn’t find what parameters are passed and what response was received, here is a link to the page .

Answer 1

F12, network and make your request. For convenience, you can clear the console before the request, then it will be the first in the list.
