To manually enter credit card transactions, you do not need any additional integration. You log on to a Web site and complete the credit card transaction using your Secure Payment Gateway Virtual Terminal. In addition, to enable your customers to make purchases right off your Web site, we give you API script to integrate into your Web site. Your customers will then be able to make purchases from your site 24 hours a day. When they do make purchases, you and your customer will receive an e-mail detailing the transaction.
