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. EU Paymentz may return a 3D Secure challenge redirect depending on the card.

Important

  • First/last name are taken from the card's own embossed cardholder name, not from customer.name.
  • If customer.email, customer.phone, or any customer.address field is missing, EU Paymentz receives a built-in placeholder value instead (a fake name, email, US address, etc.) - not an empty field. No Constants are configured for this connector to override these placeholders, so always send real customer data to avoid placeholder values reaching the provider.

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

Refunds

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

Additional info

  1. Transaction amount limits - EU Paymentz enforces a minimum of 0.01 and a maximum of 1,000,000 per transaction (in the transaction's own currency units).

FAQ / Troubleshooting

  • Invalid credentials / auth error -> verify Account ID, Password and Passphrase
  • Placeholder customer data reaching EU Paymentz -> always send customer.email, customer.phone and a full customer.address - this connector has no Constants, so anything missing is replaced with a built-in placeholder, not left empty
  • Currency or service is not supported -> confirm allowed currencies/features in your EU Paymentz account and in Corefy - only USD and EUR are available
  • Refund fails with multiple attempts -> only one refund per payment is allowed
