Frequently Asked Questions
Paywall Fraud is an intelligent fraud detection system that analyzes your payment transactions in real time and detects fraudulent attempts. With its advanced rule engine, blacklist management, and risk scoring, it protects your business against all types of fraud threats.
Yes, we offer a fully customizable rule engine. You can create both query-based and action-based rules, and define rules based on dozens of parameters such as transaction amount, card details, IP address, payment channel, and transaction time.
The system performs its checks using a wide range of parameters such as card number, IP address, email, phone number, device fingerprint, payment channel, transaction amount, currency, country code, user agent, and transaction time.
Before each payment transaction, the system assigns a score based on the fraud rules you have defined. Each triggered rule contributes to the total score, and the transaction is evaluated with a risk score between 0 and 100. According to your configured threshold values, the transaction is automatically routed to one of these actions: APPROVE, REVIEW, or REJECT.
Thanks to the blacklist structure, after a payment transaction is received, you can add records to the blacklist based on the parameters you define (Card, IP Address, Email, Phone Number, Device Fingerprint, Card BIN).
With Paywall’s standardized error codes, when a transaction fails due to a stolen card reported by the provider, you can directly add the relevant payment details (Phone Number, Card, IP Address, Email, Card BIN, Device Fingerprint) to the blacklist either temporarily or permanently.
