Introducing the New Qualtrics Developer Documentation

· 3 min read
QDP Developer Relations

The Qualtrics Developer Platform documentation has a new home. Public API reference and Extension SDK guides are now at developer-docs.qualtrics.com, replacing the previous Stoplight-hosted site. All existing bookmarks redirect automatically — no action required on your end.

The previous site was hosted by Stoplight; this new site is self-hosted and will remain so going forward.

What's the same​

All content has moved as-is. If you used the old site, you'll find everything you expect:

  • The complete Public API reference — all 321 endpoints across 46 OpenAPI specs, rendered with interactive try-it panels and code samples in multiple languages.
  • The full Extension SDK documentation — guides for every plugin type, the XMT CLI reference, and the manifest specification.

The URL structure is preserved wherever possible, and 301 redirects are in place for any paths that changed. If you have a bookmark that doesn't redirect correctly, let us know.

What's new​

The two most significant changes are unified navigation and full-site search.

Unified navigation. Extension SDK and Public API docs now live under one roof with a shared top nav and a single place to bookmark. Previously, the two sets were hosted separately with no cross-linking.

Faster search. Press Cmd+K (or Ctrl+K) from anywhere on the site to search across both documentation sets simultaneously. The search index is built at compile time, so results are instant with no external service dependency.

Also new:

  • Dark mode — toggle between light and dark themes using the button in the top-right corner.
  • This blog — release notes, tutorials, and platform updates will be published here going forward. Subscribe via RSS or Atom using /blog/rss.xml and /blog/atom.xml in your feed reader.

How to use it​

The site has two primary sections reachable from the top nav:

SectionWhat's in it
Extension SDKPlugin development guides, manifest reference, XMT CLI, authentication
Public APIOpenAPI reference for all Qualtrics public APIs, organized by spec

The sidebar on each section mirrors the structure you already know. The API reference pages include the full parameter and response schema on the left, with request/response examples on the right. New to extensions? Start with Get Started with the Extension SDK.

Feedback​

If you find broken links, missing content, or anything that worked better before, use the feedback icon at the bottom of any page to submit a response.
