GitBook is a **knowledge-only** source — OpenCX reads GitBook content into the AI training index. The GitBook source syncs the `content` stream (plus workspace metadata like users, organizations, and org members for context) from one GitBook space. Use this when your product docs, help articles, or internal runbooks are authored in GitBook. ## What you get * **Content from one space** — pages, nested pages, and their body content. * **Source URLs preserved** — the `website` or `content` URL of each page, so the AI cites accurately. * **Visibility by publish state** — published content is **public**, unpublished content is **internal**. ## Scope * **One space per connection** — add a second source if you sync multiple spaces. * **All pages in the space** — no per-page scoping. Hide pages inside GitBook if you don't want them indexed. *** ## Related Documentation Access token, space ID. Auth, wrong space, empty content. Fallback for public GitBook sites. All sources.
