Developers rate working sample code high on API documentation priority lists. At one time, sample code was supplied only for SDKs for a particular programming language.

Today, with the popularity of web APIs, sample code is often provided in several languages. You cannot possibly provide sample code in all languages that can make HTTP requests, so what should you do? Granted, your developer team probably understands the principles of writing good code, but what they may not realize is that some of the good practices they have learned for writing good production code do not apply to writing good sample code.

For example, clarity is more how to write apis than efficiency. Effective sample code should follow these guidelines: What you can do is take the time to determine which languages your API coders are using the most.

Focus on as many of those languages as you have the budget for. Having said that, be aware that most Java programmers would rather not have to look at Python code. Your user interface should be sophisticated enough to allow the user to select one language and display all sample code in that language.

A good example of this is Stripe documentationwhich uses tabs to display various languages. Having sample code that does only that is not especially useful. Instead, think about what your API does and how the sample code could demonstrate common tasks. For example, sample code that returns a user profile could then construct a string to display information about the user, such as first name and last name.

Another example would be a common workflow task where data from one request is used as parameters in another request.

Use Hard-Coded Values Every programmer knows not to use hard-coded values in code. You may be surprised to hear that you should use hard-coded values in sample code.

To group relevant information as closely together as possible. If you follow good practice for production code and define all of your constants at the top of your file, when developers look at the line of code that uses the constant they have to scroll to the top of the file to find out what its value is.

Strings, integers, hexadecimal values and other simple values should all be hard-coded right where they are used. Exceptions should be made for API keys and access tokens, which are expected to be different for each developer using the API.

Include Plenty of Comments Comments are obviously good for both production code and sample code, but they are critical in sample code.

Every class, function or method should have at least one comment line explaining what it is or what it does. You should use comments anywhere that the code is not obvious, especially if you need to document a work-around or something equally unusual.

In general, you should have a line of comment for at least every five or 10 lines of code. Use Meaningful Variable, Class and Member Names For both production code and sample code, variable, class and member names should be clear.

In sample code, though, you should take this idea further than in production code. Remember, clarity is more important than efficiency. Long, unwieldy names can be a problem in production code, but they are usually worth it in sample code because of the added clarity. You may be surprised to learn, therefore, that it is generally not desirable to create your own classes for sample code.

The object-oriented model distributes functionality so that data and functions are grouped together, and it uses inheritance to cut down on duplicate code.How to write a REST API? Ask Question.

How APIs Work

So any request sent to a server will return a lot of data, sometimes more than desired. APIs (Application Program Interfaces) define how software systems talk to each other, and API documentation is a rapidly growing field.

There is a strong need for writers who can understand APIs and explain them so that software developers can understand how to use them.
