REST stands for Representational State Transfer.
REST is one of the most commonly used approaches for building APIs because it is simple, scalable, and widely supported.
Most modern web applications communicate with external services using REST APIs to exchange information and perform actions.
A REST API exposes resources through endpoints.
An endpoint is a specific URL that allows applications to access or manage data.
For example, an application may use one endpoint for customers, another for products, and another for orders.
REST APIs use HTTP methods to define actions.
Each method represents a specific type of operation performed on a resource.
The most common methods are GET, POST, PUT, PATCH, and DELETE.
Understanding these methods helps developers design and integrate APIs effectively.
When a request is sent to a REST API, the server processes the request and returns a response.
The response usually contains information about the requested resource, operation status, or validation results.
Applications use these responses to display information and perform business operations.
REST APIs are designed to be stateless.
Each request contains all information needed to complete the operation.
The server does not rely on previous requests to understand the current request, which improves scalability and reliability.
REST APIs have become the standard communication method for modern applications.
They allow businesses to connect websites, mobile applications, SaaS platforms, payment systems, CRM tools, and countless other services.
Understanding REST APIs is a fundamental skill for developers working with Lovable AI and modern software systems.
