Overview of REST APIs

What is REST APIs

A REST API, also known as a RESTful API, stands for Representational State Transfer. It is a specific type of application programming interface (API) that follows a set of guidelines for how software programs communicate with each other.

RESTful APIs are designed to be stateless, meaning each request from a client to a server must contain all the information necessary to understand and process the request. In return, the server returns requested resources in its response (e.g., JSON format).

In simple terms, REST APIs are like using a common language (like English) and following specific rules (like grammar) to ensure everyone understands each other clearly.

Benefits of using REST APIs?

• Simplicity: REST APIs are easy to learn and understand due to their standardized nature and reliance on common protocols like HTTP.

• Flexibility: They can be used to access various data types and perform different operations on resources, making them adaptable to diverse use cases.

• Scalability: The stateless design and standardized communication make REST APIs highly scalable, allowing them to handle large volumes of requests efficiently.

• Platform independence: As they leverage HTTP and common data formats like JSON, REST APIs can be used across different platforms and programming languages.

Common use cases of REST APIs

Mobile applications

Many mobile apps use REST APIs to interact with backend services and retrieve data, such as weather information, social media updates, or product details from online stores.

Web appliactions

Web applications can leverage REST APIs to integrate with various third-party services, like payment gateways, social media platforms, or analytics tools.

Microservices architecture

In microservices architectures, individual components communicate with each other through REST APIs, enabling modularity and independent development of services.
