How to create good REST API documentation

REST (Representational State Transfer) is the go-to architectural style for APIs, and video conferencing is right there in the mix. Now that we've talked up the perks of top-notch documentation, let's dive into the must-know steps for creating the best practices for REST API documentation, specially tailored for video conferencing integrations:

The structure of API documentation

An outline

The outline in your API documentation serves as a navigational tool, directing users to the exact information they require. It presents the API's functionalities, such as endpoints and parameters, in a well-organized manner. Imagine it as a quick reference guide for developers, partners, and anyone seeking swift access to pertinent details. Here's an exemplary outline offering a glimpse into the Digital Samba documentation page:

Tutorials

Tutorials are the heart and soul of API documentation, providing users with straightforward, step-by-step instructions for utilising the API to accomplish specific tasks. Tutorials demystify the implementation process by walking users through practical examples, illuminating usage scenarios, and highlighting best practices. These tutorials not only demonstrate the API's capabilities but also empower users to integrate it into their applications seamlessly.

Authentication

Security plays a pivotal role in video conferencing platforms. In the authentication section, developers find the lowdown on securely accessing your API within your documentation. Here's what it usually covers:

  • Obtaining API keys: This section explains how developers can obtain the credentials needed to engage with the API. Clear instructions ensure that they're equipped to proceed.
  • Implementing authentication mechanisms: Here, we explore the various authentication methods supported by the API (think OAuth) and provide a detailed roadmap for developers to integrate these mechanisms seamlessly into their workflows.
  • Managing user authorisation: This aspect guides developers on how to wield the power of user access levels and permissions within the realm of video conferencing functionalities. It's all about ensuring the right folks have the right access at the right time.

Here is an example from the Digital Samba REST API Authentication documentation:

By providing clear authentication instructions, you ensure developers can securely integrate your video conferencing API, protecting user data and platform integrity.

Endpoint definition

Think of API endpoints as the doorways through which developers interact with your video conferencing platform. The endpoint definition section provides a comprehensive reference for each endpoint, detailing its purpose and functionalities. A well-structured endpoint definition should include:

  • Endpoint URL: The specific URL path used to access the functionality.
  • HTTP method: The HTTP method used for the request (e.g., GET, POST, PUT, DELETE).
  • Request parameters: A detailed explanation of the expected parameters and their data types.
  • Response structure: A breakdown of the data returned by the API in response to a request. 

Here is an excellent request-response structure on the Digital Samba REST API documentation page:

By providing clear and concise endpoint definitions, you empower developers to understand how to interact with each functionality offered by your video conferencing API.

Status and error codes

Status and error codes are like the secret language of API documentation. They're the signals that tell developers when things aren't going according to plan. These codes don't just flag issues; they also provide valuable insights into what went wrong and how to fix it. In your API documentation, error codes serve as your trusty guides, offering instructions on troubleshooting errors, handling exceptions, and resolving any other hiccups developers might encounter. They're the roadmap to smoother sailing in the world of API interactions.

Examples 

Once users grasp the inner workings of your API, examples step in to bring those functionalities to life. They're like the show-and-tell portion of your documentation, helping users visualise how the API behaves in real-world scenarios.

With examples, users get a firsthand look at how to structure requests and decode responses effectively. Take, for example, the code snippet on our site that showcases making API requests to fetch data. These snippets clearly show what goes into a request and what kind of response you can anticipate in return. It's like having a front-row seat to the API in action.

Glossary

Navigating through technical terms can sometimes feel like deciphering a foreign language. That's where a robust glossary steps in to save the day. Consider it your API dictionary, packed with crystal-clear definitions of all the essential terms, acronyms, and jargon sprinkled throughout the documentation. This glossary is particularly handy for newcomers or those just dipping their toes into the world of a specific API. It's like having a trusty guide by your side, helping you decode the language of APIs with ease.

The best practices for API 

documentation

Crafting top-notch API documentation isn't just about giving out instructions; it's about building a communication bridge that empowers developers to wield the full power of your video conferencing platform. Here are some key best practices to consider:

  1. Know your audience: Developers come in all shapes and sizes. By clearly defining your target audience, you can customise the documentation's language, depth, and level of detail. For example, documentation for external developers integrating video conferencing features may differ from internal docs meant for your engineering team.
  2. Keep it clear: Jargon-heavy docs can be a real buzzkill. Aim for clarity, brevity, and plain English. Break down even the most complex functionalities into digestible bits for developers of all skill levels. Remember, the goal is to empower, not to baffle.
  3. Stay up-to-date: API documentation is a living, breathing creature that evolves alongside your platform. Make it easy for developers to find the latest version by including prominent links within your platform and developer portal. Consider versioning your docs to ensure everyone's working with the most current info.
  4. Show, don't just tell: Don't just throw instructions at developers; paint them a picture. Incorporate code snippets showcasing how to interact with specific API endpoints. And why stop there? Toss in some real-world use cases tailored to video conferencing functionalities. This helps developers visualise how to integrate your features into their apps and troubleshoot any snags along the way. Check out this example from Digital Samba on requesting the Digital Samba API.
