Online payment fraud continues to increase year over year. IPQS enables merchants and websites that collect payments to deploy an advanced fraud detection system with seamless integration for scoring customer data. Access the most up to date blocklists generated from partnerships with financial institutions and thousands of partners that process users and payments with our real time transaction screening API. Score payment details for transaction risk with on-demand API lookups during registration, login, or checkout. Our fraud detection systems consistently update to mitigate new trends for fraudulent transactions.
Additional user data for orders, payments, transactions, lead generation, and personal user information can be analyzed to enhance the transaction risk API fraud score accuracy. The fields listed below are entirely optional and provide additional data that can be used to detect fraudulent payments and suspicious behavior likely to generate chargeback fraud disputes. Any additional data beyond the IP address greatly improves detecting high risk activity.
Transaction risk analysis on will be displayed in the "transaction_details" object. If only one address is available for the user or transaction screening process, then please enter the address data into the "billing" or "shipping" variables, rather than entering the same address in both variables. Passing the email address also contributes to detecting fraudulent users, however only a light abusive check will be performed. Using a full lookup with IPQualityScore Email Verification API Documentation is recommended as it will provide greater details and accuracy for email reputation. The transaction variables listed below are optional, any irrelevant variables can be ignored.
Stop chargebacks and prevent fraudulent transactions at checkout by implementing this easy credit card fraud detection API with your order risk scoring process. Receive real-time transaction screening analysis about a user's billing details for complete chargeback protection. Higher Fraud Scores indicate greater transaction risk, with scores >= 90 in the upper tier of suspicious payments. The transaction risk API provides additional data insight into the user's email address and phone number reputation. Stolen credit card user data submitted by fraudsters is often already blacklisted in our database due to our comprehensive data network with financial institutions.

The following variables are returned through the Proxy Detection API which provides risk analysis for users and transactions. You can also treat "billing" or "shipping" variables as a user's primary or secondary information group, even when billing is not involved, such as for lead generation or user scoring purposes.
The "risk_score" is the easiest way to consume the transaction risk data by identifying suspicious user behavior with scores >= 75 and high risk payment details or user data with scores >= 90.
These variables are populated when at least 1 transaction data parameter is present in the initial API request. The following transaction variables are "null" when the necessary transaction parameters are not passed with the initial API request. For instance, not passing the "billing_email" will return "valid_billing_email" as null.
The transaction screening API is built to enable instant payments without friction for legitimate customers.
