Fingerprint has introduced significant updates to its Server API, enhancing fraud detection capabilities by allowing users to enrich past identification events with new data and enabling the flagging of suspicious activities. These updates facilitate a more comprehensive understanding of users by linking visitor IDs with additional data like account IDs and usernames, improving the detection of fraudulent activities such as unauthorized access or fake account creation. The new PUT method allows for modifying past events with information gathered after initial identification, which can help uncover suspicious behavior that may have previously gone unnoticed. Additionally, a new feature allows users to flag events as suspicious, contributing to refining Fingerprint’s Suspect Score and tailoring it to specific environments. These developments aim to provide a more adaptive and personalized fraud prevention strategy by leveraging user data and Fingerprint's flexibility, ultimately offering a more robust protection system against evolving fraud tactics.
