1.5. Sale Form

Introduction

Sale is a type of transaction, in which Payer receives goods or services from Connecting Party in exchange for money or other assets. Sale Form integration allows Connecting Party to exclude itself from storing, processing, or transmitting Payer’s cardholder data or other sensitive payment details. Such data is submitted by Payer on Denumtech hosted payment form in PCI DSS certified environment.
All forms can be customized. Follow the Forms Customization reference to see examples and macros of Payment Page Customization, Prefilled Cardholder Data in Payment Page, Wait Page Customization and Finish Page Customization.
