What operation mode?

You need to decide which operation mode you want to run the payment gateway for your business.

Based on these two steps, you can choose between two default operation codes:

1. Authorization: an authorization transaction that reserves funds on a customer’s credit card. Authorize does not charge the card until you perform a capture transaction and/or confirm the shipment of the order (using an option available in the ePDQ back office). Note that authorization reserves funds for varying periods, depending on the issuing card company’s policy. We strongly suggest that you capture the payment as soon as the shipment has been sent.
2. Sale:  this is the most common transaction type which immediately charges a customer’s card or bank account.
