API docs

The complete API documentation platform

Create detailed, interactive API docs your users and customers will love — or generate them automatically from API definition files

Your docs just got smarter

Internal documentation tools for your whole team

Instant API code samples in the right language

API documentation in GitBook gives your users a ton of information at a glance. And because it automatically generates code samples for API endpoints, it’s easy for everyone to find and use the information and code they need.

Add context around your API operations

Organize your docs however you want. Group related operations together, or split them into different pages. Add an introduction, interactive guides, and any other content that will help your users. You have complete control.

Test your APIs right in GitBook

Let users and developers try API endpoints right on the page with our OpenAPI blocks powered by Scalar. Simply click Test It to open up an API client where you can add headers, variables and more — then run a live test.

Effortlessly add an API reference

Simply add your OpenAPI specification as a file or URL and choose which operations you want to add. It’s as easy as checking a box — our OpenAPI blocks will do the rest.

Manually add context around API blocks

Want to enhance your API documentation with getting started pages, guides and anything else that your API definitions don’t include? GitBook’s WYSIWYG editor makes it easy to structure your docs how you want.

Publish and update any time

Ready to go live? Publish in one click — literally. And if you’ve created docs using an OpenAPI file or URL, you can instantly update them whenever your API specification changes.

Review and approve updates

GitBook’s branch-based workflow will be instantly familiar to your development team. Create and edit a new branch in either GitBook or your Git repo, request a review, and merge the changes. Simple.

git Sync

Update your API docs through your codebase

With our GitHub Sync and GitLab Sync integrations, you can set up a two-way sync with your codebase. Now, when you make changes to your API, you can update your API docs at the same time — right in GitHub or GitLab.

Documentation your users will love

Customize and brand your API documentation

Change colors, add your own logo, and choose how things appear on every page. API docs in GitBook look great out of the box, but if you want to add some flair, it’s easy.

Protect access for only authorized users

Choose who gets access to your API documentation with visitor authentication. Keep sensitive information private, so only your chosen customers, team members or authorized users can view your docs.
