Direct Integration
With direct integration, your website (complete with secure certificate) captures the user's personal and credit card details and then forwards these behind the scenes to the secure Cardstream gateway. Cardstream then performs any necessary fraud and security checks, clears the payment with the acquiring bank and sends a response back to your website. Your website then delivers a formatted response back to the customer.
Direct integration is more complex than the hosted forms method, but it does mean that the entire shopping process can occur within your website, providing a more seamless experience for your customers.
