Westpac PayWay API Payment Gateway for WooCommerce GPL v1.6.4

The Westpac PayWay API Payment Gateway for WooCommerce GPL enables seamless credit card payment processing on your WooCommerce store using Westpac’s fully integrated PayWay API method. This integration allows customers to complete their transactions directly on your website without being redirected to an external payment page, creating a smooth and professional checkout experience.

By default, the gateway supports Visa and Mastercard payments. With additional activation from Westpac, merchants can also accept American Express, Diners Club, and JCB, expanding payment flexibility for customers.

Unlike hosted or redirect-based integrations, the PayWay API method processes payments securely through direct API communication between your WooCommerce store and Westpac’s servers. Because card details are handled within your website environment, your hosting server must meet PCI DSS (Payment Card Industry Data Security Standards) compliance requirements to ensure secure transaction handling.

This extension is ideal for Australian businesses already using Westpac merchant services who want tighter control over checkout experience and branding consistency.

If you prefer a hosted payment page solution where customers are redirected to Westpac’s secure environment, a separate NET (direct post) integration extension is available.
