Working with PayPal

Once you have selected the PayPal option as one of your payment options, all you need to do is enter your PayPal Business Account (sign up using your account email address). Quick Shopping Cart does the rest and even integrates with the Instant Payment Notification (IPN) service to automate order processing.

About PayPal IPN Order Processing

IPN allows PayPal to communicate with merchants to provide real-time order confirmation and processing. Using PayPal, order management is easier with immediate notification and confirmation of received PayPal payments and additional status information, such as pending, canceled, or failed transactions.
