  • Adyen labels the server alpha and pilot-stage.
  • Accounting records and invoices are financially consequential and may contain personal or tax information.
Risk contextAdyen labels the server alpha and pilot-stage. Use a test environment where practical, least-privilege credentials, narrowly enabled tools, and explicit confirmation for mutations.
