Klarna HOP Workflow
  1. The customer begins to checkout on the merchant website and chooses the Klarna payment option.
  2. The merchant sends a HOP session API request to
    Cybersource
    . For more information, see Creating a HOP Session.
    If the customer changes their purchase selection after the merchant sends the session API request, the merchant must send an update session API request. For more information, see Updating a Session.
  3. Cybersource
     responds to the merchant with an
    INITIATED
     status and a Klarna redirect URL.
  4. The merchant redirects the customer to the Klarna URL.
  5. The customer completes checkout on the Klarna hosted-page and is redirected back to the merchant website. Klarna appends a unique authorization token to the merchant redirect URL.
  6. The merchant sends an authorization API request to
    Cybersource
     and includes the authorization token Klarna appended to the merchant URL. For more information, see Authorize a Payment.

    PENDING

    AUTHORIZED
