  Fasten Connect Stitch SDK quickstart pages
note: >-
  Fasten Health ships client libraries in two shapes: npm-published Stitch SDKs for the patient
  consent widget, and Go modules for its open-source FHIR/PDF libraries. There is no first-party
  server-side SDK for the Fasten Connect REST API itself in any language — integrators are expected
  to call it directly with HTTP Basic auth (the authentication docs give raw cURL/Go/JS/Python/Java
  snippets rather than an SDK).

      The React Native quickstart's own code samples import from `fasten-connect-stitch-react-native`,
      a package name that does not exist on npm (404). The installable package is the scoped
      `@fastenhealth/...` name shown in the install command on the same page.

      CDN-distributed, not published to any package registry, and UNPINNED — the documented URL
      floats at the `/connect/v4/` major-version path, so there is no version or release date to
      read from the URL and no registry metadata endpoint to query. A consumer cannot tell which
      build they are loading, and neither can we. Recorded as null after checking, not unchecked.

      Fourth Stitch SDK target. The repository describes itself as "[ALPHA] Work-in-progress" and is
      NOT published to pub.dev (pub.dev/api/packages/fasten_stitch_element returns 404), so there is
      no released version or publication date to record. Source-only at this time; it is also not
      yet referenced from the Stitch SDK documentation, which covers Web Component, React and
      React Native only.

    note: >-
      Recommended by Fasten's Display & Component Library guide and forked into the Fasten GitHub
      org at github.com/fastenhealth/fhir-react, but the PUBLISHED npm package's repository and
      homepage both point at 1uphealth/fhir-react. It is a third-party library Fasten consumes and
      recommends, not a Fasten-published SDK. Marked official:false on that evidence.

    note: >-
      Fasten's webhook verification docs instruct integrators to use any Standard Webhooks
      implementation (JS/Go/Python/Ruby/Java) rather than shipping a first-party verification SDK.
