What is a RESTful API?

Understanding Basic Definitions of RESTful API

A RESTful API, or Representational State Transfer Application Programming Interface, is a set of rules that allow different software applications to communicate with each other. This concept might sound complicated, but think of it like a menu in a restaurant. You, as a customer, can make a request (order food) from the menu (API), and the kitchen (server) interprets your request to give you what you want (the response). RESTful API is popular because it’s easy to use and can handle multiple types of calls (requests), return different data formats and can be used over almost any protocol.

Unveiling The Magic Behind RESTful API: Decoding Its Core Concepts

Understanding RESTful API

A RESTful API (Representational State Transfer) is a set of rules that developers follow when they create their API, making it easy to use and manipulate. It revolves around the presentation, performance, scalability, and modification of network-based applications. The REST technology is generally preferred over other similar technologies for its simplicity in the integration of applications using HTTP and its long-term compatibility.

RESTfulness is an architectural style used to create lightweight, maintainable, and scalable web services. Unlike other architecture styles, REST does not enforce any rule regarding how it should be implemented at the lower level. It just puts high-level design guidelines and leaves you to decide how to implement them.

Core Concepts Behind RESTful API

One crucial aspect of RESTful APIs is the concept of statelessness. In other words, the server doesn’t remember anything about the user who uses the API. It doesn’t store any data between requests. So, each request that comes from a client must include all the information needed by the server to process that request, such as authentication and data.

RESTful APIs break down a transaction to create a series of small modules, allowing developers to construct their data interaction methods. Each module addresses a particular underlying part of the transaction. Using these modules, the API makes HTTP requests to GET, PUT, POST and DELETE data.

  • GET retrieves the resource from the server. It is a read-only method and does not affect the data on the server.
  • PUT updates a current resource with new data. It is used when you want to modify a singular, known resource.
  • POST creates a new resource. It is often used when you’re not sure what the URL of the newly created resource will be.
  • DELETE removes a resource from the server.

RESTful APIs provide a great deal of flexibility. Developers are not required to install libraries or additional software to benefit from a REST API design. REST also makes efficient use of bandwidth to conserve resources with a less latency overhead. Driven by the ever-increasing demands of mobile apps, social networking websites, and the Internet of Things, RESTful APIs have become the standard method to connect systems together. Developers who understand RESTful systems are in high-demand, for their adaptability in modern technological infrastructures.
