I don't know how I read a nested dictionary or a nested JSON file?

[Betina]

I was reading previously similar topics but I can't figure out a solution. I'm sorry if I'm redundant. I’m developing an APP that looks for a ISBN number at Google Books APIs and storages the book info title, authors, cover image link in a dictionary.
What should I do to get the data from “title”, “authors” and “smallThumbnail" labels. The only value I can read is items but I can’t access the nested labels.

URL: https://www.googleapis.com/books/v1/volumes?q=isbn:9788418915086&fields=items(volumeInfo(title,authors,imageLinks/smallThumbnail))

Text from URL :
{
"items": [
{
"volumeInfo": {
"title": "Tú serás mi muerte / You'll Be the Death of Me",
"c": [
"Karen M. McManus"
],
"imageLinks": {
"smallThumbnail": "http://books.google.com/books/content?id=gmSREAAAQBAJ&printsec=frontcover&img=1&zoom=5&source=gbs_api"
}
}
}
]
}

make request like this

https://www.googleapis.com/books/v1/volumes?q=isbn:9788418915086&fields=items(volumeInfo(title,authors,imageLinks/smallThumbnail))

and you will get data like this

Summary

{
  "items": [
    {
      "volumeInfo": {
        "title": "Tú serás mi muerte / You'll Be the Death of Me",
        "authors": [
          "Karen M. McManus"
        ],
        "imageLinks": {
          "smallThumbnail": "http://books.google.com/books/content?id=gmSREAAAQBAJ&printsec=frontcover&img=1&zoom=5&source=gbs_api"
        }
      }
    }
  ]
}

and for the above response design blocks like this

Are you looking to load a list view?

[Betina]

List or dictionary, whatever that works.
I'm testing the previous suggestion. I'm sending feedback soon.
Thanks.

[Betina]

I was totally stuck. It works! Thank you so much!
I have been trying to use "list be walking key path" without success. I followed your instructions and I see progress!
