This document walks through the key issues involved in writing API wrappers in R. Overall design APIs vary widely. Before starting to code, it is important to understand how the API you are working with handles important issues so that you can implement a complete and coherent R client for the API. The key features of any API are the structure of the requests and the structure of the responses.
Because Web APIs are still fairly new, the quality and format of their documentation varies a great deal. Good documentation is important in encouraging and keeping developers interested in your platform as well as reducing support costs.
Ideally, documentation should cover four areas, as shown in the figure above: In addition, this article describes best practices specifically for Web API documentation. Auto-generate Documentation In order to minimize the amount of work in writing API documentation, it's useful to see how much of the documentation you can create automatically.
Keep in mind that auto-generated documentation is just a starting point. You will still need descriptions of all of the elements, as well as overview material. Include Sample Code More than anything, developers like to have sample code that they can learn with and start as a base for their own work.
One of Web APIs strengths is that they are independent of platform and programming language. Unfortunately, this results in extra work when creating documentation. Do you need to create sample code for all of those languages?
That may not be practical.
Instead, find out which languages are most used by your customers and focus on those. However, samples only are not sufficient. In addition, you need a description that explains the purpose of the call and you need a table that explains each element.
We recommend a table with columns for Name, Type, Description, and Remarks.
Although the Type column provides most of the information you need regarding format, the remarks section may need to specify further. If an XML element is a date, you should specify the format of the date. If it's a time, then you need to specify its time-zone.
Explain Authentication and Error Handling Authentication is often required for Web APIs, so you will need to document how to get credentials and how those credentials are passed to the Web server.
You may need step-by-step instructions on how to obtain API keys. Sample code is often useful showing developers how the keys work.

The document covers all the aspects. How can I write one like this? Did you use any tool for that? Please suggest me, I am on my way to build our API documentation. API documentation (API docs) or API specifications (API specs) On-line or hardcopy descriptions of the API, intended primarily for programmers writing in Java. These can be generated using the Javadoc tool or created some other way. If only I had written down why I had done this. Life would be so much simpler. Documentation allows you to transfer the why behind code. Much in the same way code comments explain the why Talking through your API and design decisions on paper allows you to think about them in a more formalized way. Starting simple is the best way to.
You'll need to explain how errors are handled as well. For example, an HTTP call may request data using unauthorized credentials, or it may request an action using data that does not exist.
Right now there is no standard way to pass error information back, so developers need to understand how you are passing back error information, why an error occurs, and how to fix the problem. So you may have HTTP-related information that requires documentation as well. This can include caching, content type, and status codes.
