APIs are becoming the lifeblood of the digital landscape. They are providing a means by which third-party developers and other types of users can add functionalities to existing products. However, for third-party developers to able to solve their current problems using your API, they need to understand how best to use them. You can have the most robust API in the market, but if the users don’t know how to use it effectively, it will not gain the anticipated traction. This is where API documentation comes in handy.
This write-up will help you understand what API documentation is and why it is essential.
What is API Documentation?
API documentation is a technical manual that contains instructions on how to consume and integrate with an API effectively. It is a comprehensive technical deliverable that details how well third-party developers can utilize an API. The document could come in the form of code samples, technical writing, or case examples that detail how you can better consume an API.
When users want to utilize your API, they want to have all the information on how to incorporate it into their apps and programs. API documentation features things like functions, arguments, classes, return types, and more, all supported by example and tutorials. Traditionally, API documentation was achieved through the typical content creation and maintenance software and text editors. However, advancement in technology has allowed formats such as Swagger Specification/OpenAPI to automate the documentation process, thereby enabling development teams to design and maintain these documents effectively.
The end goal of API documentation is to provide third-party developers, who are the primary consumers of your APIs, with the best experience possible. API users want to solve daunting programming challenges by either adding functionalities to your code or creating new programs. They don’t have time to try and decipher hidden information about the APIs.
They want to understand how your API operates within the shortest time possible so that they can consume and integrate it into their software development process. This is what is known as developer experience (DX). When it comes to developer experience, users want a high-performing and easy-to-work-with API. And one integral component of delivering outstanding developer experience to your users is offering up-to-date and accurate API documentation.
Why Document APIs?
A few years ago, API documentation was not something that developers gave much attention to when launching a code. However, it has become one of the critical elements that determine the success of your API in the modern marketplace. Here is why documenting APIs has become vitally essential.
Less Baggage for Your Customer Support Teams
When you launch an API that has clear, concise, and easily understandable documentation, it reduces the number of users who spend time seeking help from customer support. This saves you a considerable amount of time and money. Lack of proper documentation means that frustrated third-party developers will rely on your support team to guide them when they are trying to integrate with your API.
More People Will Use Your Product
Nobody likes a product that doesn’t provide an outstanding user experience. API documentation has proved to be one of the most integral elements when it comes to delivering exceptional developer experience. And since the effectiveness of your API documentation is directly proportional to adoption, having a straightforward and easy to understand API user manual will get many people consuming your API.
Since documentation gives third-party developers a step-to-step guideline on how to integrate and consume your API, it becomes relatively easy for them to maintain their apps and programs. Additionally, documentation helps your internal teams to comprehend every inch of your resources and methods, thereby making maintenance and updates faster and more accurate.
Like any other product, APIs can also benefit from having brand advocates. When you provide a thorough and easy-to-grasp API documentation, more people will use your APIs. And as usual, satisfied customers are the most probable people to become advocates for your product. So, excellent documentation will lead to happier customers who will, in turn, spread awareness through word of mouth to their friends and acquaintances.

- Now it time to add your endpoint with the relative path to the base URL by clicking the +Create Endpoint icon. Then add the JSON model and hit the save button.
- Now hit the test button at the bottom of the page to see whether your API is live in the RapidAPI marketplace.
What are API Endpoints?
An API endpoint is basically the entry point in a communication channel when two applications are interacting. It is the point at which the API connects to the server. Endpoints provide a means by which APIs can access the resources they want from a server. It is a more complex terminology for a server or service URL.
