Build your checkout to present Klarna for a one-time payment — a single purchase with no saved payment method. Two decisions shape the integration:
  1. 1.
    How you present Klarna — the Klarna Web SDK (in-page pop-up) or the Klarna Payment Presentation API (full-page redirect).
  2. 2.
    Who orchestrates the payment — you (Partner orchestrated) or Worldpay (Worldpay orchestrated).
