JSON
A simple text format for data, used by most APIs, like {"name": "Anna", "age": 31}.
Definition
JSON (JavaScript Object Notation) represents data as keys and values, lists and nested objects. Testers read JSON responses to check that data is correct and complete, and edit request bodies to test validation.
In practice
The product page shows no price. The JSON response has "price": null, so the problem is in the data, not the app's layout.
