From a PCI DSS-compliant environment, you can directly integrate with the CardCorp gateway's SERVER-TO-SERVER API. Learn how to make repeated payments for instalments, subscriptions, or metered orders.

If you will use a card that was previously saved in the CardCorp gateway, see the separate instructions to create a one-click checkout.

1. Create the payment request

Use a POST request to the paymentsendpoint in the payment gateway for instalments, subscriptions, or metered orders.
