What Is WooCommerce Westpac PayWay API Payment Gateway?
WooCommerce Westpac PayWay API Payment Gateway is developed by WooCommerce and is an eCommerce plugin for WordPress. It belongs to the ecommerce category on WPExclusive, alongside other tools for professional online retailers. This extension solves the friction of external redirects by processing transactions directly on your web server.
It is specifically designed for Australian businesses using Westpac’s banking infrastructure for real-time transaction approval. Merchants can maintain total control over the user interface while relying on Westpac for secure background processing.
WooCommerce Westpac PayWay API Payment Gateway Features
The feature set is built around providing a secure, integrated payment experience that meets modern Australian banking standards.
Multi-Card Support
Westpac PayWay API processes Visa and Mastercard by default for every installation. Store owners can optionally accept American Express, Diners Club, and JCB after further activation via Westpac. This flexibility makes it a versatile choice for ecommerce stores targeting international or corporate customers who use specialized cards.
Integrated API Processing
Unlike hosted payment pages, the API integration ensures customers never leave your website during the checkout process. This creates a professional look and feel that typically helps improve conversion rates. The plugin communicates directly with Westpac servers to provide immediate approval or decline responses during the transaction.
Security and Whitelisting
Westpac PayWay API requires your web server to meet PCI compliance because card data passes through your server infrastructure. The extension facilitates this by allowing you to add your server IP address to the API Security Access List within the Westpac administration tool. This whitelisting provides an additional layer of security between your WordPress instance and the bank.
Pricing
Retail pricing starts at $79.00 USD per year for a single site license on the official marketplace. WPExclusive members access it as part of their plan.
