Merchant preference
The merchant can express their choice concerning strong buyer authentication using the vads_threeds_mpi field.
The value transmitted in the payment request has priority over the risk rules potentially defined by the merchant in their Merchant Back Office.

Exemptions | Description |
---|---|
Low value transactions | In Europe, you can request an exemption from strong authentication, for transactions of less than €30, and within the limit of either 5 successive operations or a cumulative amount of less than €100. If the amount is higher than €30, the value transmitted by the merchant is ignored and the choice of the preference is transferred to the card issuer (No Preference). For payments made in a currency other than euro, a request for frictionless is transmitted to the issuer. If the frictionless request is accepted, the transaction does not benefit from liability shift dispute by the cardholder.. If the store does not have the “Frictionless 3DS2” option, the choice of the preference is transferred to the card issuer (No Preference). |
Transactional Risk Analysis (TRA Acquéreur) | If your store has the "TRA Acquirer 3DS2" option, you can ask the issuer for an exemption from strong authentication if the amount is below the threshold set by your financial institution. If the frictionless request is accepted, the transaction does not benefit from liability shift dispute by the cardholder.. The “Acquirer 3DS2 TRA" activation option is subject to the prior agreement of your financial institution. |
