REST API and RESTful API are commonly used in client/server architecture in software development. So in this article, I will introduce you to API, Rest API and Restful API.

What is API?
An Application Program Interface (API) is a piece of middleware that allows two applications to talk to each other. You can see an example in the image below.
If user wants to book train ticket, web application will show departure time, train stations and all information, when we view from developer side, developer wants to show all information of train timetables in the web application, then the developer will use the APIs to get these train information from the web server, which stores all the train details and information. Developers can then retrieve data from the web server using the APIs to display in the web application.
Benefits of using API
APIs are required to make connections between functions in the application to process data from different processes.
● Easy integration: API can be integrated into any kind of software application, So it can be easily integrated with applications and functions between different websites.
● Reduce software development time: Using APIs that reduce development time, developers can implement their own APIs Google Maps to provide the exact location of the store to website visitors. In doing so, you won’t need to develop a GPS-based location tracking app from scratch. This approach will be more efficient and cost effective to achieve the required functionality.
● Security: The API provides a secure communication gateway for various application components to interact and exchange data.
What is RESTFUL API and REST API?
What is REST API?
REpresentational State Transfer is abbreviated as REST. It is an API that follows a set of rules for applications and services to communicate with each other.
REST APIs work by making requests for a resource and returning all relevant information about the resource, translated into a format that can be easily understood by the client (this format is defined by API requests). The client can also modify items on the server and even add new items to the server through the REST API.
What is RESTful API?
RESTful API is an Application Programming Interface (API) that follows the constraints of the REST architecture and interacts with RESTful web services. RESTful API also follows the principles of REST API. RESTful APIs are more scalable and have a longer lifespan. RESTful API uses the HTTP request to access and use data. There are four basic HTTP requests that a client can make:
● GET – To retrieve resources.
● POST – To create a new resource.
● PUT – To edit or update an existing resource.
● DELETE – To delete the resource.
Endpoints REST API and RESTful API
When a user uses the API to send “request” information from a web application or web server, it receives a “response”. Where APIs send requests or contain resources directly are endpoints. With the REST API, the endpoint is one end of the communication channel.
Difference between REST API and RESTful API
Although the architectures of both REST and RESTful APIs are similar, they are a bit different. REST API follows all the rules of REST architecture. It has a cached, stateless, client-server layer system with a uniform interface, while RESTful web applications have all the features of the REST architecture with additional features. unique fig.
This REST protocol is very powerful and it inherits many security measures, which are built-in architectural layers. In RESTful APIs there are many layers and there is a transport protocol which makes the system less secure when compared to REST.
REST API web services work on request and response. RESTful operation is completely based on REST applications.
It is highly adaptable and friendly to all business and IT enterprises using REST API. RESTful APIs are more flexible when compared to RESTLESS web services.
