  No first-party Flatpay client library exists in any public registry. npm
  `flatpay`, `@flatpay/sdk` and `flatpay-sdk` all return 404, as does PyPI
  `flatpay`. Flatpay's public GitHub presence (github.com/FLATPAY-DK) holds two
  repositories, both FORKS of unrelated third-party libraries
  (socket.io-client-java, engine.io-client-java) — neither is a Flatpay client
  library. Six further Flatpay-named GitHub orgs (flatpay-payment-tech,
  Flatpay-BI, Flatpay-AI, Flatpay-Marketing, Flatpayweb, Flatpay-Miscellaneous)
  expose zero public repositories. Webshop integration is delivered as
  "Frisbii+ Pay" plugins for WooCommerce, Shopify, Magento, PrestaShop,
  Shopware, OpenCart, Drupal, Dynamicweb, Ucommerce, VirtueMart and Ideal Shop —
  those plugins are published by Frisbii (Billwerk+), a different company, and
  are therefore not recorded as Flatpay packages.
