Frequently Asked Questions

Common questions about our Fraud Detection API.

Our API uses a machine learning model that analyzes hundreds of signals in real-time, including IP reputation, device fingerprint, behavioral patterns, and transaction data, to calculate a risk score.

You can send various data points, such as user ID, email, IP address, transaction amount, and device information. The more data you provide, the more accurate the risk assessment will be.

Yes, our Enterprise plan allows for custom modeling where we work with you to tailor the fraud detection logic to your specific business needs and risk tolerance.

'Review' suggests that the transaction is suspicious and should be manually checked by your team. 'Block' indicates a very high probability of fraud, and we recommend automatically rejecting the transaction.
