What is JSON?

JavaScript Object Notation (JSON) is a text format for representing structured data based on the syntax of the JavaScript language. The .json extension is used to identify JSON files. There are many programming languages that use JSON to exchange data, including Java, Python, JavaScript, PHP, C++, C#, Go, and many more.

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

What is REST API?

The REST API is an application programming interface that follows the principles of the REST design style or an architectural style of representational state transfer. With REST APIs, developers have access to a high degree of flexibility and freedom, which has made microservice architecture the standard way to integrate components. REST APIs are independent of browsers and programming languages. Clients of REST APIs interact with resources via HTTP protocol for standard CRUD operations.

What is an API Endpoint?

An API endpoint is a simple URL representing a collection of objects or a single object. The API sends requests to endpoints, which are locations where the resources are located. Each endpoint is a URL where APIs can access resources needed to function.
