Use the skipNonAuthenticatedCards option to reject cards that are not 3DS authenticated. If non-authenticated cards are accepted, those transactions will not be 3DS protected (no liability shift). This option is used when Secure3DS = Yes. Note: Non-3DS supported cards will be rejected if this option is checked.
No additional work is needed for pages built in CheckoutChamp. If you have built an integration using our direct API, Secure 3DS processing requires your checkout page to handle the standard 3DS workflow. Follow instructions in this document.
