  SendOwl publishes NO first-party client library for its REST API in any package registry. The API
  reference says only "We have just started a GitHub repos with code samples for different langagues"
  and links github.com/SendOwl/community-code — sample code, not a versioned, installable SDK. The
  SendOwl GitHub organization holds 17 public repositories, of which 16 are forks of third-party Ruby
  gems used internally (paperclip, mimemagic, paypal-express, imgix-rails, createsend-ruby,
  mailerlite-ruby, php-serialize, forceps, omniauth-instagram, slate-serializers and similar) and one
  is the community sample-code repo. Because no first-party API client library exists, NO `SDKs`
  pointer is emitted for this provider — the only first-party distributable is the browser-side
  sendowl.js checkout library, which is a UI/checkout component (see components/) rather than an API
  client. Everything installable that wraps the SendOwl REST API is third-party and unmaintained: the
  newest such package was last published in January 2023 and the two actual API wrappers were last
  published in 2022 and 2017.

  note: >-
    First-party, but CDN-distributed with an UNPINNED URL — there is no version segment in the path, no
    registry metadata endpoint, no jsDelivr/unpkg entry, and the served file carries no version banner
    (verified 200, application/javascript, 11,632 bytes on 2026-08-12). A consumer cannot tell which
    build they are loading and cannot pin one; the same URL silently floats to whatever SendOwl ships.
    Recorded as null because it was checked and there is genuinely nothing to record, not because it
    was skipped.

    The repository the API reference links as "Code Libraries". PHP-dominant sample code, 14 stars,
    last pushed 2022-09-03. Not published to any package registry and not versioned, so there is no
    release to record — `published` is the last push date to the default branch.

  repository: https://github.com/imreyne/sendowl-js
  note: Third-party Node.js wrapper for the SendOwl API. Name collides confusingly with SendOwl's own
    browser sendowl.js, which is a different thing.

  note: Third-party Node.js client, last published 2017 — predates the v1_2 discounts and v1_3 orders
    endpoints documented today.
