Alias Gateway enables you to post transactions to the PostFinance platform by using a payment page built by yourself:

  1. Alias Gateway: You submit the card data to our system, where it is securely stored (including the CVC, but for a limited time only)
  2. DirectLink: You submit the actual order, without needing to submit the card data.


  • You have full control over the look & feel of the payment page, including the check-out sequence.
  • PostFinance is completely invisible in the payment process.
  • Seamless integration for various checkout scenarios including One Page Checkout.
  • You can offer upselling and cross-selling on the final checkout page.
  • All major credit card brands (VISA, MasterCard, American Express, Diners) are supported, as well as Direct Debits and PostFinance Card.
