This page explains how supported card brands, billing currency, payment settlement, and 3D Secure authentication are handled for wholesale transactions processed through our iyzico payment infrastructure.

Supported cards & currency handling

Clear payment structure for wholesale transactions

Wholesale card payments on our platform are securely processed through iyzico. Supported card brands include Visa, Mastercard, American Express, and Troy, subject to issuer, region, and transaction eligibility.

Your approved billing currency is confirmed during wholesale account setup.
The final payable amount is displayed clearly before payment confirmation.
Bank transfer payments must be sent in the same currency stated on the invoice.
Where applicable, eligible cards may display installment options during checkout.
If you need clarification on billing currency or settlement terms, our team can confirm the details before payment is submitted.

3D Secure verification via iyzico

Bank-controlled authentication for added payment security

Depending on the payment flow, card issuer, and transaction profile, your payment may be processed through a 3D Secure verification step. In these cases, authentication is handled directly by the issuing bank or card provider as part of the iyzico payment flow.

You may be redirected to your bank’s secure authentication page during checkout.
The verification screen, password request, or one-time code step is controlled by your bank, not by our website.
Some transactions may proceed without 3D Secure, depending on issuer rules and payment configuration.
If authentication is not completed successfully, the payment cannot be finalized.

Payment confirmation & settlement visibility

Transparent review before approval

Before the transaction is completed, the payable total is presented for review so that billing, currency, and checkout details remain clear. This helps maintain a more transparent and reliable wholesale payment process.

The payable total is shown before the transaction is approved.
Settlement follows the approved payment method and invoice structure.
Customers should review card, currency, and billing details carefully before confirming payment.
