The card fingerprint is a unique identifier attached to each card on the platform, allowing you to spot unusual behavior. The principle is as follows:
  • A card is registered with the Card Registration endpoint
  • Once the registration process is complete, the corresponding Card object is created
  • This Card object comes with a unique Fingerprint.
The same card can be registered several times in Mangopay, and will each time get a different CardId. The fingerprint, however, remains unique and this even across platforms. You can take advantage of the following endpoints to spot unusual behaviors:
