Mask Credit Card
These functions:
  • apply on String values,
  • support all credit card types and
  • keep the original format of the credit card number. For example, if the input has 13 digits, the output has 13 digits.

A credit card number is considered invalid when it does not satisfy the Luhn algorithm.

If the input is an invalid credit card number and there is:
  • no "Invalid" output flow, the function returns null in the main flow.
  • an "Invalid" output flow, the corresponding data are sent to the "Invalid" output flow.
