When to use this endpoint

This endpoint is to be used at the end of an ecommerce transaction, after the Payments API and when 3DS response data is available

Scenario 2: Learning data

An SCA exemption check is not required, for example when a merchant's policy requires all transactions over a certain threshold to go through SCA. Data is sent to help train the risk engine for future exemption checks.

Main steps in scenario 2

1. API consumer connects to POST /sca-exemptions-data sending a request message with the original transaction details and the additional data that is available after 3DS and authorisation processing.

2. An acknowledgement flag is sent back, no further details in the response message.
