What is a REST API vs API?

A REST API (also known as RESTful API) is an application programming interface that conforms to the constraints of REST architecture. REST stands for representational state transfer. An API, or application programming interface, is a set of definitions and protocols for building and integrating application software.

What is the difference between @RequestParam and @RequestBody?

@RequestParam makes Spring to map request parameters from the GET/POST request to your method argument. @RequestBody makes Spring to map entire request to a model class and from there you can retrieve or set values from its getter and setter methods.

What is body parameter in REST API?

Types of REST API Parameters Query parameters – These are separated from the hierarchy parameters by a question mark. Request body parameters – they are included in the request body and are used to send and receive data via the REST API.


REST or RESTful API design (Representational State Transfer) is designed to take advantage of existing protocols. While REST can be used over nearly any protocol, it usually takes advantage of HTTP when used for Web APIs. … REST API Design was defined by Dr. Roy Fielding in his 2000 doctorate dissertation.

What is RESTful API example?

Examples: a GET request to /user/ returns a list of registered users on a system. a POST request to /user/123 creates a user with the ID 123 using the body data. a PUT request to /user/123 updates user 123 with the body data.

When should I use RESTful API?

REST allows for building APIs with any method, including HTTP, URLs, and JSON. SOAP only uses XML for sending data. REST is considered a simpler, more efficient alternative to SOAP because it requires writing less code to complete tasks and follows a less rigid structure and logic than SOAP.

What does a delete request do?

DELETE is for deleting the request resource: The DELETE method requests that the origin server delete the resource identified by the Request-URI. This method MAY be overridden by human intervention (or other means) on the origin server.

How do I pass body parameters in Web API?

You can pass parameters to Web API controller methods using either the [FromBody] or the [FromUri] attributes. Note that the [FromBody] attribute can be used only once in the parameter list of a method.

What is difference between REST API and RESTful API?

What’s the difference between a REST API and a RESTful one? … The short answer is that REST stands for Representational State Transfer. It’s an architectural pattern for creating web services. A RESTful service is one that implements that pattern.

What is a request body in HTTP?

Request Body is the part of the HTTP Request where additional content can be sent to the server. For example, a file type of JSON or XML. Request body tries to send additional information required by the server to process current request properly.

What is swagger API?

Swagger allows you to describe the structure of your APIs so that machines can read them. … Swagger does this by asking your API to return a YAML or JSON that contains a detailed description of your entire API. This file is essentially a resource listing of your API which adheres to OpenAPI Specification.
