JSON (JavaScript Object Notation) is one of the most popular data formats used in web development for transmitting data between clients and servers. Lightweight and easy to parse, JSON has become the standard for APIs and web services. In this guide, we will explore the structure of JSON responses and best practices for creating clear, efficient, and secure JSON data structures in your APIs.
What is a JSON Response?
A JSON response is the data your API returns to the client in the form of key-value pairs. JSON is language-independent, making it versatile for use in different programming environments. It consists of:
- Objects: Represented by {}, containing key-value pairs.
- Arrays: Represented by [], containing lists of objects or values.
- Values: The actual data (e.g., strings, numbers, booleans, null).
