I need to use the Unsplash API to display a list of pictures that come to me, the title and the author. The problem is that I do not understand how to create a model for converting JSON that comes to me so that I can get the picture, author and title. JSON has nested elements and I don't understand how to do it. How can i do this? My JSON for one picture:

 {
