OverviewIn order to be complaint with the PSD2, Amazon Pay introduced SCA for their transactions. The SCA Upgrade introduces a “Confirmation Flow” to handle Multi-Factor Authentication (MFA) when it is required. When MFA is required, the Confirmation Flow shows the credit card issuer’s MFA challenge to the buyer. After the buyer interacts with the Confirmation Flow (for example, completes the MFA challenge), the buyer is returned to the merchant’s site (for example, order confirmation page). Please update the AmazonPay checkout workflow after a buyer initiates their order completion and before you call the Authorize Operation. ChangesNew JavaScript function confirmationFlow()Due to MFA, it is necessary after a succesful confirmation of an order to start a new call, the ConfirmationFlow. To start the workflow, please execute a Confirm on the order on the | Multiexcerpt include |

, after you receive a result start the confirmationFlow in case of success with "confirmationFlow.success()" in case of failure "confirmationFlow.error()" aborts the process.

On "Order Now" the merchant has to send the URLSuccess and URLFailure in the calls (EventToken=SCO | COD), because the redirect is executed after the MFA challenge. After "Order Now" the Confirm (EventToken=SCO | COD) is executed on the payment and then the redirect to the challenge takes place using the JavaScript code shown above.
