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. Gate Express may return a 3D Secure challenge redirect depending on the card.

Payment - MIN

  }
}

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 Gate Express's asynchronous callback and relies only on an active status request to finalize the payment.

Constants (fallback fields)

• CVV -> used only for CVV-exempt UZS payments: when no CVV is collected, this value (default 123) is sent as the card's CVC field instead of leaving it empty. Has no effect on any other currency.

Refunds

Gate Express supports partial refunds, but only one refund per payment (no multiple partial refunds against the same payment).
