The transaction history table in the subscription view shows each transaction’s reference, type (initial/recurring), status, amount, associated order (with link), and date.

When a customer proceeds to checkout, the Airwallex payment option appears on the payment selection step.

The option is labeled ‘Pay by Airwallex payment’. The behavior depends on the configured checkout mode.

Hosted Checkout Mode

When ‘Payment through hosted payment page’ is set to Yes, clicking the Airwallex payment option redirects the customer to Airwallex’s secure hosted checkout page.

The page displays the order total, currency, and line items. After successful payment, the customer is redirected back to your store’s order confirmation page.

Embedded Checkout Mode

When ‘Payment through hosted payment page’ is set to “No”. An inline card form is rendered on the checkout page using the Airwallex JavaScript SDK.

Customers enter their card number, expiry date, and CVC directly in a secure field hosted by Airwallex.

Real-time validation indicates whether the card number, expiry, and CVC are valid.

Subscription Product Experience

When a product is assigned a subscription plan, customers see a purchase option selector on the product page and in the cart.

They can choose between a one-time purchase and subscribing to the product with the selected billing frequency.

• On the product page, a subscription selector appears below the price showing ‘One-time purchase’ (standard pricing) and ‘Subscribe’ (recurring with the plan’s interval phrase, e.g. ‘Same price, every month’).
• In the cart, a badge ‘Subscription product’ appears next to assigned products.

• Cart conflict handling: if a customer tries to add a subscription product while another subscription product is already in the cart, a warning will display ‘Only one subscription product can be purchased in a single checkout.’

• If a customer tries to mix subscription and non-subscription products in the same cart, the subscription product will block and an error message will display at the top of the cart.

Customer Subscription Management Page

Logged-in customers can access their subscriptions via the ‘My Subscription’ link in their account navigation. This page lists all subscriptions associated with the customer’s account.

• The list shows: subscription ID, status, subscription code, Airwallex subscription ID, payment source ID, next billing date, and action buttons (View and Cancel).
• Clicking ‘View’ opens the subscription detail page showing full billing information, period dates, payment history, and a cancel button.

• Clicking ‘Cancel’ prompts for confirmation. If confirmed, the subscription will be cancel at Airwallex and the local record will update.
• Cancelled subscriptions display a ‘Cancelled’ label instead of the cancel button.
