Detailed Overview

Connect WooCommerce with Westpac PayWay

WooCommerce stores need a payment gateway that can communicate with the payment provider and return transaction results to the store.

WooCommerce Westpac PayWay API Payment Gateway provides the connection between WooCommerce and the Westpac PayWay API.

After configuration, customers can select the PayWay payment method during checkout and submit their payment through the supported PayWay workflow.

The exact payment fields, authentication requirements, transaction methods, currencies, and available options depend on the PayWay service, merchant account, API version, and plugin implementation.

WooCommerce Checkout Integration

The gateway adds PayWay to the WooCommerce payment workflow.

A typical customer journey can be:

  1. Customer adds products to the cart.

  2. Customer proceeds to checkout.

  3. Customer enters billing and shipping information.

  4. Customer selects the configured PayWay payment method.

  5. Payment information is submitted through the supported gateway process.

  6. PayWay processes or authorizes the transaction.

  7. The payment response is returned to WooCommerce.

  8. WooCommerce updates the associated order according to the returned result.

This creates a connected payment workflow between the storefront, WooCommerce, and PayWay.

On-Site Payment Experience

Where supported by the configured PayWay API integration, customers can complete payment without being sent through a separate external checkout page.

Keeping payment interactions within the store's checkout can provide a consistent shopping experience.

However, the exact behavior depends on the PayWay API implementation and the payment method being used. Some payment flows may require additional authentication, verification, or provider-specific steps.

Credit Card Payments

The gateway is designed to support credit card payment processing through the configured Westpac PayWay service.

Depending on the merchant account and PayWay configuration, supported card types and payment options may differ.

Before launching the gateway, confirm the accepted payment methods directly with Westpac PayWay and verify that the plugin supports the required transaction flow.

API Credentials and Configuration

The gateway requires the appropriate PayWay connection information.

Depending on the PayWay API version and plugin configuration, you may need to configure items such as:

  • Merchant credentials

  • API credentials

  • API endpoint

  • Sandbox/test settings

  • Production/live settings

  • Transaction configuration

  • Payment method settings

  • Currency configuration

  • Other provider-specific options

Only use the credentials and settings provided for your own PayWay merchant account.
