PayWay is an initiative from Westpac to simplify this integration process by providing a certified credit card processing API that overcomes the difficult development task of integration and security. Westpac will authorise the credit card transaction in real-time, providing you with an immediate approve or decline response. You will receive same-day settlement for Visa and MasterCard transactions completed before 6pm Sydney time.
And this Plugin allows Gravity Forms to accept Credit Card payments on site without redirecting the customers. Thus enhancing the user experience.
