Getting started with API documentation tools in modern development workflows

Source: Dev.to

Introduction

Hi everyone 👋

I’m currently exploring different tools and approaches for API documentation and testing, especially in modern development workflows involving microservices and external integrations.

Background

As a beginner/intermediate developer, I’ve noticed that API documentation is often:

• outdated quickly
• disconnected from actual testing
• hard to maintain across teams

So I’ve been trying to understand what real‑world teams use to solve this problem.

Some common approaches I’ve seen so far:

• OpenAPI / Swagger‑based documentation
• Separate tools for testing and documentation
• Integrated platforms that try to combine both workflows

One tool I came across during my research is Apidog, which combines API design, testing, and documentation in a single workflow. It looks interesting for keeping everything in sync, especially for small teams.

Questions for the Community

• What do you use for API documentation in your projects?
• How do you make sure your docs stay updated as your API evolves?
• Any tools or workflows you would recommend for someone starting out?

Thanks in advance for sharing your experience.
