- Additional Data Transactions
3D secure 2 is the latest standard released by EMVCo that allows merchants and payment service providers to send additional data elements to the issuing bank of the cardholder, which in turn, makes it possible for the issuer of the card to perform frictionless authentication and offer an improved, user experience to the cardholder. With the additional data elements relating to the cardholder, issuers can apply "Frictionless" Authentication flows or “Challenged” authentication flows
Frictionless Authentication Flows: issuers can apply risk-based decisions using the additional data received and trust that the real cardholder is making the purchase and auto authenticate the transaction in the background without requesting any additional information from the cardholder.
Challenged Authentication Flows: When the issuer cannot apply risk-based decision using the data on record, additional information to authenticate the payment is then requested from the cardholder.
Integrating 3DS 2 via the iVeri Gateway
The following information is crucial before starting an integration to the iVeri Gateway,
Generate a certificate ID in the the merchant portal - Backoffice
- The use of the certificate ID is only applicable on the Debit or Authorisation messages
- The Auth/Debit payment instructions can be contrusted in JSON or XML using the REST and SOAP API
Merchant Profile
A merchants test application ID must be enabled for 3DS 2. Contact iVeri support on assist@iveri.com to enable 3D secure.
- 3D secure test cards
3DS 2 Endpoint
Method: POST 3D secure requests on - https://[portal base domain]/threedsecure/EnrollmentInitial
Format: FormData
3D Secure Process
- Submit 3D secure request in a Form POST or Pop-Up method
- Post request on /threedsecure/EnrollmentInitial
- The iVeri Gateway will act as proxy and submit the 3D secure request to the 3DS MPI onbehalf of the merchant
- 3D secure MPI, will return the status to the iVeri Gateway
- iVeri Gateway will post the status of the authentication to the merchant ReturnURL.
- Depending on the data set returned, the merchant can proceed with the payment instruction ( Debit/Authorisation) or the transaction will have to be terminated to the customer.
