This topic explains how to configure Afterpay as a third-party payment provider in StoreConnect.

What you need

Afterpay is supported on StoreConnect web storefronts only and is not available for POS.

Refer to Afterpay docs if needed.

Sandbox access

To test your integration, request sandbox credentials from Afterpay.

  • Sandbox access may take several business days to provision
  • Credentials are provided by Afterpay’s technical team

Configure Afterpay in StoreConnect

Basic configuration

  1. Open StoreConnect and go to Settings > Payments > Payment Providers.
  2. Select New.
  3. Complete the fields as follows, then Save.
StoreConnect field Select or enter
Name Afterpay
Provider Select Afterpay
API Mode sandbox or production
API Key API Key (Username) from Afterpay
API Secret API Secret (Password/Secret Key)
API Option to enable 3DS three_d_secure: true
API Option merchant ID (required) merchant_id: your_merchant_id
API Option to show Afterpay wallet show_wallets: true
API Option to enable express checkout express_checkout_enabled: true

API Modes

  • sandbox — for testing with Afterpay sandbox credentials
  • production — for live transactions

When using sandbox, StoreConnect automatically routes requests to Afterpay’s test environment.

API Options (example)

three_d_secure: true merchant_id: XXXXXXB03CUR9012345 show_wallets: true express_checkout_enabled: true

Checkout behavior

When a customer checks out with Afterpay, StoreConnect sends itemized product lines and any discount entries to Afterpay, giving shoppers a clear order breakdown within the Afterpay payment UI.

If the customer modifies their cart in another browser tab after starting the Afterpay payment flow, StoreConnect detects the change and prevents the payment completing against the stale cart total. The customer is returned to the cart to restart checkout with the updated amount.

Troubleshooting

  • Ensure API Mode matches the credential type (sandbox vs production)
  • Confirm credentials are entered correctly
  • Verify Afterpay messaging is visible on product pages
  • Check with Afterpay if sandbox access has not been provisioned
