Document the ins and outs of your APIs to ensure those who interface with your applications are successful and those who enhance your products have a manageable framework they can reference. Programming and technical writing expert Peter Gruenbaum knows that APIs are becoming increasingly more complex. That's why, in this course, he helps you establish strong, foundational skills in web API documentation by demonstrating how to document structured data using data-interchange formats. Peter shares the benefits of creating good documentation, explains the differences between responses and requests, and discusses how to work with common data types—from numbers and text to arrays and dictionaries. He then shows how to create and document using JSON and then XML. He wraps up the course by examining the pros and cons of available documentation tools and collaboration tools like wikis and knowledge bases.
