![]() ![]() Cache : Because a stateless API can increase request overhead by handling large loads of incoming and outbound calls, because for each request and response it creates a new connection, a REST API should be designed to encourage the storage of cacheable data.Once the request is sent by the client it closes the connection and establishes the new connection to give the response. ![]() Stateless : REST APIs are stateless, meaning that it does not save history of any request or response.Client-Server : This concept explains that the client and the server should be separate from each other and allowed to evolve individually.The data can be sent or received in the form of JSON or XML. REST stands for REpresentational State Transfer, just like regular websites, REST APIs use HTTP for communication. SOAP was designed to work with XML and have some sort of specification which could be used across all applications. SOAP stands for Simple Object Access Protocol. But there are no standard specifications on use of XML across all programming languages for data exchange. Hence, XML was used as the underlying medium for data exchange. SOAP API :Įvery programming language can understand the XML markup language. The API, therefore, lets you know how to write out the commands to make the box do stuff. In other words, it is an interface for programming the application (the box). The interface is the understanding between you and the box. In this example, the application is the box itself. When you press the button, the black box lights up. In general terms, it is a set of clearly defined methods of communication between various software components.Įxample : Imagine you’ve got a black box with a big red button on top. ![]() First we need to know about API.ĪPI is an interface or a software intermediary that allows two applications to talk to each other. SOAP and REST are the APIs(Application Programming Interface). ![]()
