Which client can effectively use a Web API?

• A. Only desktop applications
• B. Only HTTP clients with a GUI
• C. Clients that support HTTP verbs like GET and POST
• D. Only mobile applications

Answer: (C)

The correct answer indicates that clients capable of using a Web API are those that support HTTP verbs such as GET and POST. This understanding is fundamental because Web APIs primarily communicate over the HTTP protocol, which relies on these HTTP methods to perform actions on resources. HTTP verbs correspond to specific actions: GET is used to retrieve data from a server, while POST is employed to send data to a server for new resource creation or for submission of data. If a client can invoke these methods, it means that it can effectively send requests to and handle responses from a Web API. Clients such as web browsers, mobile applications, and even desktop applications that implement HTTP clients can utilize this functionality. The other options are restrictive or incorrect because they limit the scope of clients that can interact with Web APIs. An effective client is not confined to just desktops or mobile applications; rather, it's defined by its ability to interact through the necessary HTTP verbs. Thus, any application or system, regardless of the platform, that can execute these HTTP methods can effectively leverage Web APIs.
