What is A Fraud Prevention API?

Fraud Prevention APIs allow businesses to pass user and payment data in real-time through an application programming interface (API), enabling a real-time third party risk assessment during account creation, payment or transaction, or similar action. The API request returns a fraud score and similar reputation metrics based on the user or billing details to accurately analyze risk. The business can then block the account sign up or payment based on the risk factors identified by IPQS.

When To Use a Fraud Prevention API?

Using a Fraud Prevention API is a best practice to detect fraud during an important action point such as account registration or during a shopping cart checkout or payment. This tool can help companies of all sizes mitigate risk and identify bad actors. Depending on the risk score, suspicious users or payments can even be subject to additional verification methods instead of being outright blocked for high risk behavior.

How Does a Fraud Prevention API Detect Fraud?

User data processed through to the IPQS Fraud Detection API uses advanced risk scoring from a suite of APIs such as IP reputation, email fraud detection, and email address risk assessment. Additionally access intelligent bot mitigation that detects bots and non-human traffic with the ability to block bad requests in real-time.
