php - Is It possible to find necessary parameters 4 GET/POST requests in jQuery.ajaxSettings?

one text

Let me begin by saying that everything I do is for educational purposes only. It's really interesting and important to understand "how it works". That's all. Nobody, nobody is hurt. So, right know I am learning reverse engineering and I was stooped with understanding of Jquery.ajaxs, 4 example I have a source and I know how to get many Interesting things(go to source and in browser, console puts '> ECProductImpressionTrackingArray'):

Among other things, I found link, Its serves to get product data and now I am interesting, If it possible to find "the right query params" to get data. Maybe I can do it with 'jQuery.ajaxSettings' or should I find it in another place. By the way, why people still use jQuery, is its safety?

Thanks in advance!

P.S. Found smth interesting:
