1.6. Preauth Form, Capture and Cancel

Introduction

Preauthorization is a transaction type in which bank blocks the specified amount in the Payer’s card account and does not allow the cardholder to use this blocked money. It is important to know that the block remains for a definite period of time depending on whether this is a debit or a credit card (usually the maximum block period is 7 days for debit cards and 28 days for credit cards). Preauth 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 Billblend hosted payment form in PCI DSS certified environment.

Capture is a transaction followed after preauth which deducts the locked amount from Payer’s card.

Cancel is opposite of Capture which cancels the deduction and returns locked amount back to Payer’s card.

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.
