  PPRO ships exactly one first-party client library, and it is a checkout UI SDK rather than an API client.
  There is no published server-side SDK for the Global API in any registry — no npm package other than the
  Drop-in Checkout, nothing on PyPI (pypi.org/pypi/ppro/json returns 404), nothing under a PPRO namespace on
  Maven Central, NuGet, RubyGems, Packagist, crates.io or pkg.go.dev, and the developer hub's own "Tools"
  section lists OpenAPI generation, Postman, MCP and llms.txt in place of SDKs. That is a real finding, not a
  gap in the search: PPRO's stated integration path is "use our OpenAPI spec to generate client libraries".

  description: >-
    Drop-in Checkout — a single component rendering cards, wallets, bank redirects, BNPL, stablecoins and cash
    payment methods across 24 markets, with card number and CVV held in PPRO-hosted iframes so the integrator
    stays out of PCI scope.

  repository_public: false
  repository_note: >-
    The npm metadata names a GitHub repository, but the PPROGroup organization exposes no public repositories,
    so the source is not readable. Only the published package is.

    The only first-party package was published 2026-07-31, less than a month before this harvest, against a
    Global API whose most recent documented change is May 2026. No abandonment signal.
