Which architectural style is NOT commonly used for creating a Web API?

• A. HTTP for client-server communication
• B. XML as a formatting language
• C. Simple URI as the address
• D. Graphical User Interfaces (GUI)

Answer: (D)

The option indicating Graphical User Interfaces (GUI) is the architectural style that is not commonly used for creating a Web API. Web APIs are primarily designed for server-client communication, which generally relies on protocols like HTTP and data formats such as JSON or XML for request and response payloads. The main purpose of a Web API is to facilitate programmatic access to services over the web, allowing different software systems to communicate. APIs operate on a defined set of rules and data structures that are meant to be consumed by other applications rather than by human users directly. GUIs are focused on user interaction and are designed to be visual interfaces for end users, making them unsuitable as an architectural style for APIs, which are meant to expose functionalities programmatically. In contrast, client-server communication utilizing HTTP, the use of XML as a formatting language, and defining simple URIs are foundational concepts in API design. These elements ensure effective communication between services over the web, making them integral to the architecture of a Web API.
