Introduction
Payment Fraud Scoring APIs help businesses detect, assess, and prevent fraudulent payment activity by analyzing transactions in real time using risk models, behavioral analytics, device intelligence, identity verification, machine learning, and transaction scoring systems. These APIs assign fraud risk scores to payment attempts, helping merchants, fintech companies, banks, and marketplaces make automated approval, review, or rejection decisions.
