summary: >-
  Kueski ships no conventional server-side API client library in any language. Its distribution
  model is e-commerce platform plugins plus a browser widget bundle: a merchant installs a
  first-party plugin for their storefront platform, or drops in the widgets.js script. Searches of
  npm, PyPI, Packagist, RubyGems and crates.io return no first-party Kueski client library. The
  packages below are the real, first-party, publicly distributable artifacts Kueski does publish.

platform_integrations_without_public_packages:
  note: >-
    Kueski documents installation guides for these platforms but does not distribute the module
    through a public package registry — merchants obtain them through the platform's own app store
    or from Kueski directly.
  platforms:
  - {platform: Shopify, guide: 'https://github.com/kueski-dev/Dev-Center/wiki/Shopify'}
  - {platform: Magento, guide: 'https://github.com/kueski-dev/Dev-Center/wiki/Magento'}
  - {platform: PrestaShop, guide: 'https://github.com/kueski-dev/Dev-Center/wiki/PrestaShop'}
  - {platform: Tiendanube, guide: 'https://github.com/kueski-dev/Dev-Center/wiki/Tiendanube'}
  - {platform: T1 Paginas, guide: 'https://github.com/kueski-dev/Dev-Center/wiki/T1-P%C3%A1ginas'}
registries_searched:

- {registry: nuget, query: kueski, first_party_client_libraries: 0}
- {registry: pkg.go.dev, query: kueski, first_party_client_libraries: 0}
gaps:
- No server-side SDK in any language. A merchant not on one of the seven supported storefront
  platforms must hand-roll HTTP against an API that has no published specification.
- widgets.js is unversioned at the URL and offers no SRI/integrity hash, so merchants embed a
  mutable third-party script into their checkout with no pinning option.
- No public source repository for any of the plugins; the WooCommerce plugin's source is only
  obtainable by unpacking the distributed WordPress.org zip.
