First request to Corefy API (MIN)

What it does: creates a payment-invoice; card data itself is collected and submitted separately by Corefy's checkout/SDK layer, not as part of this request. CVV is always required (no CVV-exempt mode), and 3D Secure control is not configurable for this connector.

    }
  }
}

Important

No Constants are configured for this connector - if a customer field is missing, it's simply not sent, unless generate_customer_date_of_birth is enabled (see Options below).

Extended request (MAX)

Why add extra fields (typical reasons): - Provide additional customer details for compliance/reconciliation - Positively influence conversion rate - Include optional fields required by your specific flow

Options

  • ignore_callback -> optional, boolean - for cascading to work correctly, ignores CDN's asynchronous callback and relies only on an active status request to finalize the payment.
  • generate_customer_date_of_birth -> optional, boolean - when customer.date_of_birth is missing, generates and sends a synthetic date of birth to CDN instead of leaving the field empty.

Refunds

CDN does not support refunds.

Additional info

  1. Active reconciliation is available - both the asynchronous callback and an active status request can finalize the payment, unless ignore_callback is enabled.
  2. No recurring - this connector does not support saving/charging a token through Corefy.

FAQ / Troubleshooting

  • Invalid credentials / auth error -> verify the Merchant ID and key pair for the selected environment (test_mode)
  • Payment declined for missing cardholder date of birth -> enable generate_customer_date_of_birth, or send customer.date_of_birth yourself
  • Currency or service is not supported -> confirm allowed currencies/features in your CDN account and in Corefy - only EUR and USD are available
  • Refund fails -> CDN does not support refunds through Corefy
