It is one of the most frequently asked Web API Interview Questions in Web API Interviews. What are the differences between REST and SOAP? For example, a client cannot ordinarily tell whether it is connected directly to the server or to an intermediary along the way. REST allows us to use a layered system architecture where we deploy the APIs in server A, and store data on server B and authenticate requests in server C. Each resource is identified by a specific URI (Uniform Resource Identifier). The HTTP verb (GET, PUT, POST, PATCH, and DELETE) that is sent with each request tells the API what to do with the resource. The Product, Employee, Customer, Country, State, City, etc.

In the context of a RESTFUL Service, resources typically represent data entities. To understand the uniform interface constraint, first, we need to understand what a resource is and the HTTP verbs such as GET, PUT, POST, PATCH, and DELETE. The Uniform Interface Constraint defines an interface between the client and the server. The Cacheable Constraint says that let the client know how long this data is good for so that the client does not have to come back to the server for that data over and over again. In real-time applications, some data provided by the server is not changed that frequently like the list of Countries, the list of States, the list of cities, and some master data. This ensures that each request can be treated independently by the server. The request from the client should contain all the necessary information so that the server can identify the client and can process that request. That means the server should not be storing anything on the server related to the client. The stateless constraint specifies that the communication between the client and the server must be stateless between requests. The next constraint is the Stateless Constraint. Severs and clients may also be replaced and developed independently as long as the interface between them is not altered. A client should only know resource URIs and that’s all. That means client applications and server applications should be developed separately without any dependency on each other. This separation of concerns supports the independent development of both client-side and server-side logic. This constraint specifies that a Client sends a request to the server and the server sends a response back to the client. The REST architectural pattern specifies a set of constraints that a system should be adhered to. REST architectural pattern treats each service as a resource and a client can access these resources by using HTTP protocol methods such as GET, POST, PUT, PATCH, and DELETE. REST is an architectural pattern for exchanging data over a distributed environment. The REST was first introduced in the year 2000 by Roy Fielding as part of his doctoral dissertation. REST stands for Representational State Transfer. If you are preparing for ASP.NET Web API Interviews then definitely you have to prepare this Web API Interview Question. It is not a replacement for SOAP What are the RESTful services?.The REST architectural pattern treats each service as a resource and a client can access those resources by using HTTP Protocol methods such as GET, POST, PUT, PATCH, and DELETE. and the server can also be on any platform like Java. Distributed environment means the client can be on any platform like Java. In Rest, there is something called Client and Server, and the data can be exchanged between the client and server over a distributed environment. This is an architectural pattern used for exchanging data over a distributed environment. These services can then be consumed by a broad range of clients like ASP.NET Web API is an ideal platform for building Restful services.

ASP.NET Web API is a framework that makes it easy to build Web APIs, i.e. HTTP based services on top of the. The term API stands for Application Programming Interface.
