WooCommerce Westpac PayWay API
This extension allows you to use Westpac PayWay API as a credit card processor, using their fully integrated API process. You can process Visa and Mastercard by default, and can optionally accept American Express, Diners Club and JCB after further activation by Westpac.
When using the PayWay API integration, you should ensure your web server meets PCI compliance (Payment Card Industry Data Security Standards).
Note: Another extension is available if you wish to use the NET (Westpac-hosted direct post) integration.
