Connect Shopify to your CardCorp payment gateway with Chopify.

Chopify store settings

The settings you configure for your Shopify Checkout do not apply to the Chopify Checkout.

Always select the Live theme so your checkout will collect payments correctly

Chopify will always charge the customer in the store currency
