In today's age of integration, seamless data exchange between systems is critical. For example, Uber relies on Google Maps for location access and PayPal for payments. At the heart of these interactions lies the API (Application Program Interface), which enables communication between different applications. While there are various ways to build APIs, two essential methods to consider are REST and RESTful APIs.

Although these terms might seem interchangeable, they have distinct roles. REST (Representational State Transfer) is an architectural style with specific constraints, while RESTful APIs refer to services that adhere to these principles. Understanding the subtle differences is crucial when discussing software architecture within your development team. This blog will clarify the nuances between rest api vs restful api, helping you better understand their functions, applications, and how they can enhance your next project.

What is a REST API?

A REST API, or Representational State Transfer API, is a style of architecture that lets computers talk to each other over the Internet using HTTP requests. Its purpose is to ensure that systems can safely access and share data, which makes it an important part of current web services and apps. Roy Fielding invented REST in 2000, and it has since become a common way to do things in software engineering.

An API is a list of rules developers set up on the server side so that programs can talk to each other. REST tells developers what design techniques to use and how to organize and work with these APIs.

REST APIs adhere to key principles, including:

• Layered System: REST elements can only be used in the layer they are given to. This makes it easier to use proxies and load balancers and makes scaling easier.
• Uniform Interface: A standard layout across all of its parts makes things simple and consistent.
• Cacheability: Responses are tagged with whether they can be cached. This improves speed by allowing the right information to be cached.
• Statelessness: Servers don't keep track of what the client is doing; each request has all the information it needs to be processed, which makes growing easier and handling client contacts more efficiently.

REST APIs are a powerful, scalable, and reliable way for systems to interact over the web.

What is a RESTful API?

RESTful APIs are interfaces that let different systems safely share data over the Internet. They are based on the ideas of REST (Representational State Transfer) and make it easy to create APIs that work with many computer languages and systems. A standard way of building web services makes RESTful APIs flexible and reliable, which is why they are used extensively in web development.

RESTful APIs can manage data well by following REST's design rules. This makes it easier to handle different types of data. They mostly talk to each other through HTTP messages necessary for current web stacks. Some important parts of RESTful APIs are:

• Headers: These take care of details, connection types, and other data in requests and replies.
• Data: The real information that the client asked for is in the body of the API call.
• Methods: HTTP standard ways change data, such as GET, POST, and DELETE.
• Endpoints: URLs that specify where data is located on the server.

RESTful APIs have many benefits, such as using less data, supporting multiple formats, being easy to learn, and being flexible. They are great for public and private services because they are widely used, especially in SaaS apps.
