Check the Card Security Code

If your application requires it, you can check the Card Security Code (CSC). This four-digit code is printed at the back side of the card if so ordered.

The endpoint to check the card security code is POST /api/v2/Loyalty/MerchantCards/{id}/checkCsc:

The result signalizes whether the CSC was valid (true) or invalid (false). If the CSC is invalid you must not use the card.
