What Are Rest APIs and How do Rest APIs Work?

REST API is a type of web service that enables communication between software applications over the internet. It follows the REST architectural style, providing principles for building scalable and flexible distributed systems. At its core, REST APIs use HTTP methods (such as GET, POST, PUT, and DELETE) to allow clients to perform operations on server-hosted resources. These resources are exposed through unique Uniform Resource Identifiers (URIs) that act as addresses for accessing and manipulating them.

When a client wants to interact with a REST API, it sends an HTTP request to the server, specifying the desired method and resource URI. The server processes the request, which may involve retrieving data, updating records, or executing business logic. Once the server completes processing, it returns an HTTP response with a status code indicating the success or failure of the request, along with any data or error messages. REST APIs commonly use JSON or XML as data formats for request and response bodies.

An important characteristic of REST APIs is their stateless nature, where each request is independent and doesn’t rely on previous requests or server-stored information. This allows for easier scalability and distribution of the system. By adhering to REST principles, APIs provide a standardized and uniform way for different applications to communicate and exchange data. They have become widely adopted for building web services used by various clients, including web browsers and mobile apps.

What is API Integration Meaning?

API integration allows different software systems to collaborate and share information effortlessly. It connects various applications using a set of rules and protocols called an Application Programming Interface (API).
