API reference that does not drift from the API
Generated from your OpenAPI specification, updated when the spec changes, and sitting in the same portal as the guides that explain how to actually use it.
- OpenAPI 3.1
- Eight languages of samples
- Guides and reference together
How does TheDocs generate API documentation?
You upload an OpenAPI specification or point TheDocs at a URL it polls. TheDocs generates reference pages for every endpoint - parameters, request and response schemas, error codes and authentication - with code samples in eight languages and an optional try-it console. When the spec changes, TheDocs shows a diff including breaking changes and republishes on your approval. Hand-written guides live in the same portal and search, so developers do not have to choose between reference and explanation.
- OpenAPI 3.0 and 3.1, plus Swagger 2.0 with conversion.
- Pull from a URL or push from CI on release.
- Spec diffs highlight breaking changes before publish.
- Code samples in curl, JavaScript, Python, Go, Java, PHP, Ruby and C#.
- Hand-written prose per endpoint survives regeneration.
- Optional try-it console against your sandbox.
What a developer gets
Reference alone is not documentation. Neither are guides alone.
A navigable reference
Endpoints grouped by tag, with search across paths, parameters and descriptions. Deep-linkable, so a support engineer can send a link to one field.
Samples they can paste
Generated per endpoint in eight languages, with the reader's own key substituted when they are signed in. Replace any of them with your own.
A try-it console
Calls your sandbox from the docs, shows the real response, and never requires a Postman collection to get started.
Errors documented properly
Every error code with its cause and what to do about it - the section that actually reduces support load.
Guides beside the reference
Authentication, pagination, rate limits, webhooks and quickstarts as written articles, in the same search index as the endpoints.
Changelog from the spec
A generated API changelog with added, changed, deprecated and removed operations, so integrators can see what affects them.
Keeping it honest as the API moves
Sync from your pipeline
Documentation drift is a release-process problem, not a writing problem. It is fixed where the release happens.
- Push the spec from CI on merge or on tag, using an API key scoped to that project.
- Or give TheDocs a spec URL and a polling interval - useful when the spec is already published.
- Every import produces a diff: new operations, changed schemas, removals, and anything that breaks a consumer.
- Auto-publish non-breaking changes and hold breaking ones for review, if that is the balance you want.
- Tie an API version to a documentation version so v2 reference and v2 guides stay together.
Breaking-change detection is conservative. It flags anything a reasonable consumer could depend on, and you dismiss what does not matter.
Where humans add value
A generated reference tells a developer what the field is called. It does not tell them why they would use it.
- A prose block per endpoint and per schema field that is never overwritten by regeneration.
- Recipes: multi-step tutorials that reference live endpoints and stay linked as they change.
- Conceptual guides on auth, idempotency, pagination and rate limits, written once and linked from every relevant endpoint.
- Deprecation notices with a migration path, shown on the endpoint rather than buried in a changelog.
