1 Introduction

One Page Checkout with FlexCheckout enables you to request your customers to introduce their card details safely on the PSP system, tokenize these data and re-use the Token (or Alias) in a future transaction.


  • You have full control over the look & feel of the payment page via the flexible template mechanism. You can even control the check-out sequence in an iframe.
  • You have the advantage of a secure, PCI compliant payment page without having to store the card data yourself; all sensitive data is directly introduced on our hosted page.
  • Seamless integration for various checkout scenarios including One Page Checkout.
  • You can offer up-selling and cross-selling on the final checkout page.
  • Supports all major credit card brands (VISA, MasterCard, American Express, Diners) .
