  npm registry (registry.npmjs.org), Packagist (repo.packagist.org), pub.dev,

description: >-
  First-party Klarna client libraries. Klarna publishes NO server-side REST SDK for the
  Payments / Order Management / Settlements APIs in any language — the only maintained
  first-party libraries are the mobile (Android / iOS / React Native / Flutter) in-app SDKs
  and browser-loaded JavaScript libraries served from Klarna's own CDN. The one historical
  server-side SDK, the PHP klarna/kco_rest library, is marked ABANDONED on Packagist and
  its GitHub repository is archived as [DEPRECATED].

    note: >-
      A Swift Package Manager distribution of the same SDK is published separately at
      https://github.com/klarna/klarna-mobile-sdk-spm; SPM has no version metadata endpoint,
      so the CocoaPods trunk record above is the dated registry evidence.

      (Android 2.13.2 / iOS 2.9.0) by nearly two years.

      Probed 2026-08-27, HTTP 200, 484 KB of application/javascript. The distribution is
      UNPINNED — the URL names only the major line `v1` and floats to whatever Klarna has
      deployed, so there is no version a consumer (or this pipeline) can read. That is the
      finding, not a gap: an integrator cannot tell what build they are loading either.

      Flagged `abandoned` in Packagist metadata; the GitHub repository
      https://github.com/klarna/kco_rest_php is titled "[DEPRECATED] Official PHP SDK library
      for Klarna Services". Last release 2020-02-14 — more than six years behind the APIs it
      wraps. Recorded as decay evidence, not as a recommended integration path.
