The payment gateway is fully integrated with Shopify. If you're already using Shopify, you can start accepting payments through our gateway by configuring a few settings.


  • Payments: Completed on your checkout page
  • 3DS: Additional set up and cost with Cardinal Commerce
  • Refunds: Handled directly in the Shopify Admin Portal

Due to restrictions imposed by Shopify, local payment methods are not supported.
