Interval limits for 3DS automatic activation

For cases where the interval limits for automatic activation of 3DS are configured in the merchant and a value of authenticate is passed in the creation of the transaction, the Carat Portal will only accept the value of authenticate passed if the transaction is between the activation limits. And if the 3DS automatic activation interval limits are configured in the merchant and an authenticate value is not passed in the transaction, the value 1 will be assumed as the default for the authentication type. Important: intervals that allow the use of 3DS and anti-fraud together must not be used. More information at Integration specific parameters.

Antifraud over 3DS

It is possible to configure in the merchant a parameter for activating anti-fraud if the chosen brand does not support 3DS. If the transaction using a merchant with this configuration is marked with 3DS (with authenticate = 1) and the card used is not supported on the 3DS Server (brand was not certified or card out of range in the 3DS base for authentication), then Payment Online will not deny the transaction and will follow the payment flow using anti-fraud ("enabled_after_auth"). Please contact our support team to find out how to enable this setting.
