I'm curious about the strategies different teams are using to keep their API documentation updated in 2025. It seems like many teams still face challenges with this, as documentation often falls out of sync right after new endpoints are deployed. Has anyone found effective ways to automate this process or has anyone tackled this problem directly? I've been exploring options like auto-generating documentation from OpenAPI specs, syncing API tests with documentation, and integrating doc updates into CI/CD pipelines. We've looked into tools such as Swagger, Redocly, Stoplight, DeveloperHub, Apidog, Docusaurus, ReadMe, and Slate. What's working for your teams? Are you automating updates, or is it still a manual task?

The key for us has been generating OpenAPI specs directly from our code. It creates a strong link between the implementation and the documentation. However, keeping infrastructure documentation current requires extra effort, as things can easily become outdated.
Totally agree, the farther you get from the actual implementation, the more intentional we have to be. It's easy to let things slip otherwise!
Honestly, a lot of teams still don’t have their documentation sorted. I think they struggle with keeping things updated due to lack of resources or discipline. Rarely do you see teams actively maintaining their docs unless there's a clear system in place.
Right? It feels like there’s always that moment when someone suddenly realizes the need for documentation, but it usually never gets finished properly!
For our team, we just use a simple setup where every backend build produces a Swagger.json file that updates a hosted Swagger UI automatically. As long as developers write annotations correctly, it works like a charm!
That's a solid approach! Have you ever tried using AI tools to assist with automatic annotations?
We've adopted a 'docs as code' approach, where if a pull request doesn't include an update to the documentation, it's not accepted. This has worked wonders in ensuring that documentation stays in sync with new code changes. Plus, we have strict testing coverage requirements that make sure everything is documented appropriately before a feature can go live.
This method is spot on! Automating documentation tools can sometimes lead to discrepancies, especially if developers don't fully understand the tools. This often ends up slowing down QA processes too. Keeping documentation linked to PRs makes collaboration much smoother.
That sounds tough, but it ensures quality. If developers keep ignoring doc updates, they'll just create more issues!
We've had great success by integrating documentation processes into our CI/CD pipelines. Using Stoplight has really eased versioning and automating updates. Documentation is now a part of our workflow, making things way more efficient and consistent!
Does that mean you use some SSG or documentation generator, like Hugo? I'm really curious about how CI/CD specifically ties into your documentation strategy.

Exactly! Generating code from OpenAPI specs sounds fantastic, but I've seen cases where the implementation changes and the documentation doesn't follow through. It's crucial to have intentional practices to keep everything aligned.
