Westpac PayWay API for WooCommerce is a payment gateway that allows you to use Westpac PayWay API as a credit card processor, to accept Visa and Mastercard by default, and optionally American Express, Diners Club and JCB after further activation by Westpac.
*Note: Another extension is available if you wish to use the NET (Westpac-hosted direct post) integration.
