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.

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 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.
