Accertify is an American Express company that handles fraud prevention and chargeback management for retailers, airlines, travel operators and gaming platforms. The StackAI integration reads from two of its APIs: a workflow can pull the dispute cases a team still needs to answer, and check an email address, IP address, phone number or card against the risk history Accertify has accumulated for it. Outcomes go back the other way, so a confirmed fraud case improves later scores.
