An introduction to 3DSV2 is available in the section 3D Secure - Strong Authentication for Secure Payments |
The 3DS V2 protocol supports 150 data points transmitted to the issuer. However, processing these data points by the issuers can be time-consuming. Therefore, it is recommended to share the most essential and effective data points with the issuer to benefit from 'frictionless' payments.
In a payment request, the merchant must mandatorily transmit the following data:
- Card data in compliance with PCI DSS requirements
- Transaction data: identification numbers, currency, and amount
- Browser data: User location and connection system (language, screen size, IP address, etc.)
- Cardholder data: User's first and last name
- Recurring payment data (if using recurring payments)
To promote frictionless payments, the merchant can:
- Provide additional data
- Indicate their preference for frictionless payment
- Request an exemption
Provide additional data in the payment request
Certaines données complémentaires sont fortement recommandées pour améliorer l’analyse de risque de la transaction par l’émetteur :
- les données sur l’adresse de livraison : ville, code postal, pays…
- Les données sur les détails de la livraison (date de livraison)
- Les données sur le compte de l’utilisateur (date de création du compte chez le commerçant, date de réinitialisation du mot de passe, etc)
- Les données panier (Nombre d’articles dans le panier)
- Le scoring commerçant
Some additional data are highly recommended to improve the transaction risk analysis by the issuer:
- Shipping address details: city, postal code, country, etc.
- Delivery details (delivery date)
- User account information (account creation date with the merchant, password reset date, etc.)
- Basket data (number of items in the order)
- Merchant scoring
The following JSON objects can be added to payment requests:
customerInfo
- billingAddress
- shipping
- browserInfo
The recommended data are as follows:
- Nom et prénom
- Adresse email
- Numéro de téléphone fixe
- Numéro de téléphone portable
- Adresse de facturation
- Adresse de livraison
- Adresse IP Cardholder information:
- First name and last name
- Email address
- Landline phone number
- Mobile phone number
- Billing address
- Delivery address
- Browser information (depends on integration):
- IP address
Note: All this data will be used to secure the online process with the aim of fighting fraud. Issuing banks are regulated in the management of these confidential data.

The addition of these additional data without an explicit request for 'frictionless' payment corresponds to the 'no Preference' case. In this case, if the payment is 'frictionlessfrictionless', the transfer of responsibility liability shift to the issuing bank applies. For more details: Liability Shift and 3D-Secure Matrices |
Indicate a 'frictionless' payment preference
L’objet The JSON threeDsPolicy permet au commerçant d'indiquer son souhait d’offrir un parcours frictionless à son acheteur.object threeDsPolicy allows the merchant to indicate their preference for offering a frictionless journey to their buyer.
The challengePreference parameter indicates the merchant's preference regarding authenticationLe paramètre challengePreference indique la préférence du commerçant vis-à-vis de l’authentification :

Les banques doivent toutefois demander une authentification si l’exemption a été utilisée cinq fois depuis la dernière authentification réussie du titulaire de la carte ou si la somme des paiements exemptés précédemment dépasse 100 €.

- Pour bénéficier de cette exemption, le commerçant doit contacter son chargé d’affaires.
An exemption from strong authentication may be granted. This requires prior agreement from the acquirer (based on a real-time risk analysis of each transaction).
