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, login, or similar action. Instantly enable a complete fraud detection system for any action of your website or mobile app. 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 or fraudulent transactions. 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.
What is a Fraud Detection API?
A Fraud Detection API is the best solution for on-demand fraud detection and risk analysis to mitigate risky behavior. Block fraud with a proprietary risk score generated in real-time by our fraud detection APIs. Analyze users, accounts registrations, or payments made at checkout to detect fraudulent behavior like fake accounts, suspicious payments, and chargebacks generated from fraudulent transactions. Prevent abusive behavior, bots, and bad actors by deploying a fraud detection API on your website.
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. When you use IPQS risk scoring services, you are deploying a comprehensive fraud detection system which has been fine-tuned through over 10 years of technology supporting thousands of B2B customers. Our fraud detection strategy models are always updating to maintain an edge over high risk users and sophisticated fraudulent activity signals.
