- Understand the API's users. As with any content strategy plan or UI design process, the first step of writing API documentation is understanding the target audience.
- Map out the user journey. Like any other product, APIs must provide content for every stage of the buyer’s journey. That means documentation should explain what the API can do (or what problems it can solve), the variety of functions and endpoints it offers, and how it’s different from competitors.
- Start with the fundamentals. Every API is unique. There’s an API for embedding Instagram photos on an ecommerce app. There’s an API for providing access to thousands of hotels on a travel blog.
- Add code examples. API documentation has two main goals: to make it as easy as possible for developers to start using the API and to make them quickly understand the API’s full potential.
After receiving a valid request from the product webpage, the API calls to the external program or web server, in this case, the third-party payment system. The server sends a response to the API with the requested information. The API transfers the data to the initial requesting application, in this case, the product website.

Mar 28, 2023 · API Documentation should reflect the actual API implementation at all times. In other words, the documented interface should be in sync with the implementation of the interface. Client code will be created or generated from the documentation; if out-of-sync, a successful invocation of the API is likely to fail.
There are many tools available for generating and maintaining API documentation. Many of these tools can automatically generate both static and interactive API documentation from an API definition file (more about this later in the article). API documentation should provide an example of every call, every parameter, and responses for each call.
