Which of the following elements are included in "well documented" APIs?

• A. What is it?
• B. What does it do? (Not how it works!)
• C. All details
• D. Source code internals

Answer: (D)

A well-documented API typically includes clear and concise information that allows users to understand how to effectively utilize the API without needing to dive into the internal workings or source code. The element "What is it?" helps users quickly grasp the essence of the API: its purpose and identity. Meanwhile, "What does it do? (Not how it works!)" focuses on the functionality and use cases of the API, explaining its practical applications and benefits without overwhelming users with technical details. This is critical for user engagement and ensuring that developers can see the value of integrating the API into their applications. The choice that includes "All details" might imply an unnecessary depth of information that could confuse rather than educate users. Documentation should aim to strike a balance, providing sufficient detail to be informative while remaining accessible and user-friendly. Source code internals, by contrast, are usually not required in documentation aimed at users. This type of detail is more relevant for developers contributing to the API or engaging in maintenance. Therefore, the focus in good API documentation is on what the API does and how it can be applied in real-world scenarios, rather than on the underlying implementations.
