The Merchant Warrior payment gateway allows you to use Merchant Warrior as a payment processor for your WooCommerce store. The extension supports Payframe (including 3D Secure), Transparent Redirect and PayID.
Process Visa and Mastercard in AUD and NZD by default, and optionally accept other currencies and American Express, Diners Club and JCB with approval.
With Payframe and Transparent Redirect, credit card details are sent directly from your checkout page to Merchant Warrior servers where they are processed, and the user is redirected to your Thank You page. Credit card details never touch your server, so PCI compliance is not necessary to ensure a seamless customer experience.

Setup and Configuration

About PayID
↑ Back to top- You complete initial setup of PayID including generating your store’s PayID email address and notifying Merchant Warrior of your Notification URL.
- A customer chooses PayID as their payment method during checkout.
- On the order confirmation page, and in the order confirmation email, the customer will be shown the PayID email address and the reference number (order number) to include. The order will be placed into On Hold status.
- When Merchant Warrior receives the PayID payment, it will send the information to your Notification URL. The plugin will look at the reference and description fields to try to find a matching order.
- If a matching order is found and the payment amount is correct, the order will be marked as payment completed.
- If a matching order could not be found (for example if the customer omits the reference number), or the payment amount is incorrect, a notification email will be sent to you with details of the PayID payment. This will need to be manually reconciled with the order.
Setting up PayID
↑ Back to top- To enable PayID for your WooCommerce store, click on WooCommerce | Settings from the left hand menu, then the top tab “Payments”. Click on “Merchant Warrior PayID” in the list.
- Configure the options:
- Tick to “Enable this payment method”.
- The “Title” option allows you to determine what your customers will see this payment option displayed as. You might choose for this to be something like “Merchant Warrior PayID” or “PayID”
- The “Enable Test mode” option allows you to test transactions with this payment gateway to ensure your details are correct. See below for testing details.
- Add your Merchant Warrior UUID, API key and API passphrase in the respective fields. You will need to provide all three.
- Enter a short version of the name of your store in the PayID Identifier field, then click Register (Test) PayID. This will register a new PayID with Merchant Warrior which looks like an email address. Please note: your live and test PayIDs will need to be registered separately. To generate your live PayID, you will need to disable the Test Mode toggle above and then ensure you have registered a live PayID.
- You will need to advise Merchant Warrior of your Notification URL. Below the PayID Identifier field is a handy email shortcut to email your UUID and Notification URL to Merchant Warrior support. Without Merchant Warrior updating your Notification URL, you will not be able to automatically reconcile PayID payments.
- Enter a Notification Email where you would like to receive emails about PayID payments that were unable to be automatically reconciled with orders. These will need to be manually reconciled and the order status updated manually.
- Save changes and you’re all done!
