Authentication and Authorization via Snap*

3-D Secure 2.0 is a protocol that was developed in compliance with the PSD2 mandate to make online payments more secure through advanced cardholder verification. The first step in the process is to authenticate the cardholder inline of transaction processing. The full flow is offered to integrators who wish to perform both Authentication protocol through Snap* as well as use Snap* front-ends for Authorization. These updates will be supported for the eService and TRON front-ends.

Snap offers integration to the Browser and Application flows for the protocol.

Documentation on implementing this feature can be found here: 3-D Secure 2.0 Full Feature Integration Guide (Last updated: 28 September 2022).

Note: Integrating to 3-D Secure requires integration to CWS, as well. Click here for the CWS Overview.
