    Pay Kit JavaScript SDK - loaded from the Cash App global CDN (must not be bundled). Renders
    the desktop QR / mobile redirect Cash App Pay flow and emits lifecycle events
    (e.g. CUSTOMER_REQUEST_APPROVED). Entry point window.CashApp.pay({ clientId }).
  official: true
notes: |
  Cash App Pay ships no first-party server-side REST SDK on npm/PyPI/Maven Central (partners
  integrate the Network/Management/Customer Request REST APIs directly and use Pay Kit only for
  the client-side checkout surface). The Afterpay Global API is likewise integrated directly over
  HTTPS. Only official first-party client SDKs are listed.
