What is the meaning of REST API?

A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services. REST stands for representational state transfer and was created by computer scientist Roy Fielding.

What is a REST API example?

For example, a REST API would use a GET request to retrieve a record, a POST request to create one, a PUT request to update a record, and a DELETE request to delete one. All HTTP methods can be used in API calls. A well-designed REST API is similar to a website running in a web browser with built-in HTTP functionality.

What is REST API and its types?

REST (representational state transfer) is a very popular web API architecture. To be a REST API, an API must adhere to certain architectural constraints, or principles, including: Client-server architecture: the interface is separated from the backend and data storage.

What is REST API why we use it?

One of the key advantages of REST APIs is that they provide a great deal of flexibility. Data is not tied to resources or methods, so REST can handle multiple types of calls, return different data formats and even change structurally with the correct implementation of hypermedia.

Is REST API frontend or backend?

REST and GraphQL are both standard ways to develop backend APIs. But over the past decade REST APIs have dominated as a choice for developing backend API’s. And many companies and developers use it actively in their projects.

What is difference between API and REST API?

The primary goal of API is to standardize data exchange between web services. Depending on the type of API, the choice of protocol changes. On the other hand, REST API is an architectural style for building web services that interact via an HTTP protocol.

What are the principles of REST API?

REST principles are defined by four interface controls, including identifying resources, managing resources through representations, self-descriptive communications, and hypermedia as the engine of the application state.
