What is JSON?

JSON (stands for JavaScript Object Notation) is a format for storing and transmitting data over a network, used in almost all scripting languages, including Java, JavaScript, PHP, Python, C++, C#, Go, and many others. Web applications use JSON to exchange data between a web browser and a server and exchange data between servers via REST or JSON APIs. JSON file names use the .json file extension.

JSON Example
{
  "Id": 78912,
  "Customer": "Jason Sweet",
  "Quantity": 1,
  "Price": 18.00
}

APIs are usually readily available to developers, well documented, suitable for use in version control systems, and conform to HTTP and REST standards.

What is JSON API?

JSON API is a specification for how clients should request data from the server and how the server should respond to those requests. JSON API is designed to minimize the number of requests and the amount of data transmitted between clients and servers. The JSON API is fully described on JSONAPI.org
