The question, “What is the best software to make documentation?” is quite popular and understandable. As a rule, people tend to use the same software for documentation when they start to work on the project. And if it doesn’t have all the needed features, you search and test different softwares.
An API documentation tool helps you reduce the time it takes for your developers to write and maintain documentation for your APIs, provide a common set of documentation that is used across all of your APIs and provide a consistent user experience for users from one API to another.
The purpose of this article is to help you find the best software for making documents, if this is what you are looking for. This article comes down to two main parts: the first part deals with all kinds of software designed to make documents; the second part deals with software that can be used within a document, with no relation to other applications.
What is API documentation software?
It’s a software system that lets developers create documents based on the inner workings of an API, how it functions, and what it’s able to do. It develops and stores a reference manual for both technical and non-technical staff to read and understand, as well as make adjustments as the development process progresses. Additionally, the software makes it easy to explain to new users and customers how to use the API to its full potential.
Of what does API documentation consist?
API documents contain detailed API descriptions, including its functions, workflows, return types, arguments, and classes. A typical API documentation set consists of several elements such as a quick start guide, explanations for every API request, authentication info, request, return, code samples (with response descriptions and error messages), and SDK examples.
What are some API documentation best practices?
Whether you’re creating documentation for web or RESTful APIs, make sure to plan for the documentation process. This includes knowing the capabilities, purpose, and scope of the API, as well as wh the documentation is for (the target audience). Furthermore, avoid jargon as much as possible and make the documentation easy to understand even for non-technical users. Lastly, include as many interactive examples and visual aides as possible.
How much does an API documentation software cost?
Different software companies have different prices for their API documentation and deployment tools, ranging from free to $399 per month. Some firms offer an enterprise pricing and service package based on the client enterprise’s needs. These packages usually have the highest functionality (for more significant enterprises) and cost more than a standard monthly package.
What is the best API documentation software?
The software tools mentioned in the list above can quickly produce high-level API documentation. For now, SwaggerHub ranks at the top of the list due to its ideal combination of enterprise-grade features, an extensive range of tools for personnel with all levels of technical knowledge, and support for several programming languages. That said, the overall quality of an API documentation software depends on your specifications and your documentation needs.
An API documentation Software is a documentation solution that helps developers and technical writers design and unify the documentation structure.
Developers: This group of people use API documentation Software to design, author and publish API reference manuals.
Technical Writers: The technical writers use these Software to explain how the API functions and how users can integrate it into their websites or applications.
Testers: API testers use these tools to check whether the API is accurately documented.
Engineers: Software engineers use these tools to ensure that they develop standardized APIs across business IT architecture.
How Does API Documentation Software Work
Every documentation provider has a customized way of how the Software should work. However, here is a highlight on the general process of how these solutions work.
Whichever Software you settle on, below are the steps for you to follow.
• Create an account with the documentation tool provider.
• Specify the metadata of the API. (Metadata denotes the version of the API.)
• Provide a name and a short description of the API.
• Highlight the resources used by the API.
• State the type of actions one can use on each resource.
• Spell out the parameters required to perform a given request.
• Give examples and sample codes.
• Have a glossary of terms used
• Publish the document.
Moreover, the tools allow users to make relevant changes and updates to the documentation.
Many businesses are using digital platforms to reach customers and for conversions. Consequently, there is a significant growth of online shoppers through mobile devices. Due to these factors, there is a push for applications that can integrate other software for efficiency.
As such, there is a rapid increase in the use of APIs. IT teams need to create APIs that are easy to use and integrate. Therefore, the usage of documentation Software will help to reduce the complexity involved in the API documentation. These tools will also help teams save the time and resources required to build the reference guide.

Why need API Documentation?
Good documentation is critical for the developer experience, which has an impact on API adoption and long-term success. A well-structured and well-written documentation that explains how to utilize and integrate an API successfully is beneficial to developers.
The reason for this is that no matter how effective an API is for establishing and extending your software services, it is useless if the developer does not understand it.
API documentation explains how to utilize an API and what services it provides. Thus, technical users, wanting to move forward in their software development, should be able to easily understand the value and usage of your API by referring to your documentation.
The overall experience of the developer when discovering, learning to use, and finally integrating with an API is termed as developer experience. The developer experience is critical to the adoption and long-term success of an API, hence good documentation is critical.
API documentation is an important part of any software development cycle. Thousands of developers rely on API websites for performing tasks like reporting bugs and offering suggested improvements. Which is why, if you plan to use an API in the future, it’s a good idea to read more about best api documentation software first.
