How to put the data that I see in the response preview?

There is a slider on the website. When the page is initialized it is not loaded completely. For example slide 3 of 100. When you switch the slide, a post request is sent and the response coming for the next slide.

I can see these data in the response preview. And how do I get them from there to put?

To send a post request in a cycle in which vozvrashenie fields will be inherited by subsequent queries.
