What is client and server in API? A server is used by the application that receives client requests, and contains resources that the client wants. The server has an API to interact with clients without giving them direct access to content stored in its database.

What are REST API principles?
REST principles are defined by four interface controls, including identifying resources, managing resources through representations, self-descriptive communications, and hypermedia as the engine of the application state.
Why is REST API called REST?
A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services. REST stands for representational state transfer and was created by computer scientist Roy Fielding.
What is difference between API and REST API?
The primary goal of API is to standardize data exchange between web services. Depending on the type of API, the choice of protocol changes. On the other hand, REST API is an architectural style for building web services that interact via an HTTP protocol.

Why is REST API popular?
RESTful APIs are the most commonly used APIs in the world of web services. They use Hypertext Transfer Protocol (HTTP) requests to create, read, update, and delete (CRUD) data. They are popular because of their simplicity, scalability, speed, and ability to handle all data types.
What is difference between RESTful and REST API?
Put simply, there are no differences between REST and RESTful as far as APIs are concerned. REST is the set of constraints. RESTful refers to an API adhering to those constraints. It can be used in web services, applications, and software.
One of the disadvantages of RESTful APIs is that you can lose the ability to maintain state in REST, such as within sessions. It can also be more difficult for newer developers to use. It’s important to understand what makes a REST API RESTful, and why these constraints exist before building your API.
Is RESTful API hard to learn?
REST uses HTTP methods for communication and most of us are familiar with the HTTP verbs such as GET, POST, PUT or DELETE. These methods are self-explanatory that what it does (in case if you don’t know these terms) and that makes REST easy to learn.
What is restful API alternative?
GraphQL. Graphql focuses on data instead of resources and operations to be performed on the resources. You can fetch different sets of data with filters applied using Graphql with a single POSt method. In REST different endpoints are needed to gather information across multiple HTTP calls, minimizing API calls.
How many types of API are there?
There are four widely agreed-upon types of web APIs: open APIs, partner APIs, internal APIs, and composite APIs.
How many days will it take to learn API automation?
API Test Automation. Take an intensive 40 hours course to learn how to automate API calls and develop Test Automation to make your testing more efficient.
Is API Testing in demand?
To ensure that each of these components work as expected, knowing what to test for and how to test at the API level is rapidly becoming an indispensable skill for every software tester.
An API test is generally performed by making requests to one or more API endpoints and comparing the response with expected results. API testing is frequently automated and used by DevOps, quality assurance (QA) and development teams for continuous testing practices.
Which is better UI or API testing?
API testing mainly concentrates on the business logic layer of the software architecture and won’t concentrate on the look and feel of an application. Whereas In USER INTERFACE TESTING (UI Testing) is used to identify the defects in a product/software by testing using Graphical user interface [GUI].

Is Selenium used for API testing?
Selenium Is Not a Tool for API Testing
Well, of course, if you have a user interface-based or custom framework which is built around the Selenium web browser, you could easily extend that framework to include API testing, but you need a different tool or library for doing that.
Do people still use Selenium?
Though companies and individual developers have been trying out new test automation tools, Selenium is still the most preferred framework for web automation testing. Many QA engineers have the misconception that Selenium is not enterprise-worthy just because it’s a free tool.
Can Selenium make API calls?
You can use tools for REST API Testing like RestCase, Runscope or vRest. There are also many rest clients available like Postman and etc.. He did ask for alternatives — and I agree, Selenium can of course make the calls; however, there are much better tools available for proper functional API testing.
Due to its aforementioned limitations and the following merge with WebDriver (resulting in Selenium 2), it was soon deprecated and is no longer supported.
Why Cypress is faster than Selenium?
A key difference is that Cypress as a tool is ideal for introducing developers to test automation rather than just a replacement for Selenium. This is why Cypress is among the fastest-growing automation tools in the world. On the other hand, Selenium is a more general-purpose tool targeted at a broader audience.
Does Selenium need coding?
Some of the pros of Selenium are that it’s free, open-source and supports multiple browsers, operating systems and programming languages. Some of the cons are that it requires coding skills, it takes time to set up and maintain, and it requires third party integrations to carry out many testing processes.
Is Selenium only for UI testing?
Selenium automates web browser Interaction, where test scripts are written to perform different user actions on the web application UI. This makes Selenium apt for UI Testing along with cross browser testing since it can perform the same tests on different browsers and browser versions.
Why is Selenium better than tools?
Selenium is the most popularly used freeware and open source automation tool. The benefits of Selenium for Test Automation are immense. Importantly, it enables record and playback for testing web applications and can run multiple scripts across various browsers.
