REST API Automation Testing from Scratch - REST Assured Java - Introduction to REST API and Where it is Used in Project

The video explains the concept of APIs as a middle layer between client and server, facilitating communication and data exchange. It highlights the independence of APIs from programming languages, allowing seamless integration across different systems. The video uses a hotel reservation system as an example to demonstrate how APIs work in real-world scenarios, emphasizing their role in simplifying client-server interactions and enabling language-independent data transmission using formats like JSON and XML.

What is the primary role of an API in a client-server architecture?

• To store data in the database

• To act as an interface between client and server

• To directly connect the front end to the database

• To replace the need for a server

How does the front end communicate with the API?

• Via email communication

• By sending data in CSV format

• Using HTTP protocol

• Through direct database queries

Which data formats are commonly used to send information to an API?

• CSV and TXT

• JSON and XML

• HTML and CSS

• SQL and NoSQL

What is the responsibility of a developer when creating an API?

• To write the entire back end code in one language

• To ensure the API captures and sends information to the correct method

• To design the front end interface

• To manage the database directly

In the context of APIs, what is the significance of JSON?

• It is a database management system

• It is a front end framework

• It is a data format used for communication

• It is a programming language

How do APIs facilitate integration between different websites?

• By sharing entire back end code

• By merging databases

• By exposing APIs for specific functionalities

• By using the same programming language

What is the full form of API?

• Application Protocol Interface

• Automated Process Integration

• Application Programming Interface

• Advanced Protocol Interaction
