What is RESTful API?

RESTful API, or Representational State Transfer, is an architectural style used for designing networked applications. It provides a set of guidelines and best practices for building web services that can be consumed by other applications over the internet.

Key Concepts

RESTful APIs are based on the following key concepts:

• Resources: APIs are built around resources, which can be any information or entity that needs to be exposed to other applications. Resources are typically identified by unique URLs.
• HTTP Methods: RESTful APIs use standard HTTP methods to perform actions on resources. The most common methods are GET (retrieve), POST (create), PUT (update), and DELETE (remove).
• Uniform Interface: APIs follow a uniform interface that defines how clients interact with resources. This includes using standard HTTP status codes for response messages and providing self-descriptive messages using hypermedia.
• Statelessness: RESTful APIs are stateless, meaning that each request from a client to the server should contain all the necessary information needed to process that request. The server does not store any session state for the client.
• Hypermedia: RESTful APIs may include hypermedia links in the responses, allowing clients to discover and navigate related resources dynamically.

Benefits of RESTful API

RESTful APIs offer several benefits:

• Scalability: RESTful APIs are designed to be scalable, allowing applications to handle a large number of concurrent requests.
• Interoperability: RESTful APIs use standard protocols and formats like HTTP and JSON, making them easily consumable by a wide range of client applications.
• Simplicity: The use of standard HTTP methods and status codes simplifies API development and makes it easier to understand and use.
• Flexibility: RESTful APIs allow clients to retrieve and manipulate resources in various formats, enabling them to integrate seamlessly with different platforms and technologies.
• Decoupling: APIs decouple the client and server, allowing them to evolve independently. This enables easier maintenance and updates without impacting the clients.
