Error Failure code: 321, when paying for the order

Description of the error that occurs when there is no authentication by 3ds

3D Secure (Three-Domain Secure) is a secure authentication protocol for CNP (Card-Not-Present) transactions that adds an extra layer of security when making online payments for goods and services.

This error means that the card you are trying to use does not support 3D Secure, which requires transaction confirmation via a one-time code.

Failure code: 321 (3D Secure authentication failed)

In this case, the bank declines the payment.

If you encounter this error, try using a different card or an alternative payment method such as PayPal. You can also contact your bank to check whether 3D Secure can be enabled for your card.
