Online fraud prevention is most effective when systems continuously learn from real transaction outcomes. While fraud screening tools can assess risk during checkout, the final payment result whether approved or declined by the payment gateway, provides valuable intelligence that can further improve fraud detection accuracy.
The FraudLabs Pro Payment API allows merchants to send the final payment outcome back to the fraud detection system. By reporting these real payment results, merchants help FraudLabs Pro refine its risk analysis and strengthen fraud prevention for future transactions.
What Is the FraudLabs Pro Payment API
The FraudLabs Pro Payment API enables merchants to submit the final status of a payment order after it has been processed by the payment gateway. This API includes the Feedback Payment API, which reports whether a payment was successful, declined or otherwise rejected.
Sharing this information helps FraudLabs Pro to understand how payment gateways ultimately responded to the transaction. When enough feedback is collected, the fraud detection engine can better identify patterns associated with fraudulent or legitimate payments. As a result, merchants benefit from more accurate fraud scoring, fewer false positives and stronger protection against suspicious transactions.
Why Payment Feedback Matters for Fraud Detection
Fraud detection systems typically evaluate transactions using various data points such as IP address, email reputation, device fingerprint and behavioral patterns. However, one of the most important signals is the actual outcome of the payment. For example:
- A transaction flagged as suspicious might still be approved by the payment gateway.
- A seemingly normal transaction could be declined due to payment fraud indicators detected by the gateway.
By reporting these outcomes through the Payment API, merchants allow FraudLabs Pro to correlate fraud risk scores with real-world payment results. Over time, this feedback loop significantly improves the accuracy of fraud analysis.
How the Feedback Payment API Works
After the payment process is completed, merchants can send the transaction outcome to FraudLabs Pro using a simple POST request.
POST https://api.fraudlabspro.com/v2/payment/feedback| Parameter | Type | Description |
| key | string | Required. API license key. |
| string | Required. Email address of the payment order. | |
| status | string | Required. Status of the payment order. |
| message | string | Required. Message returned from the payment gateway for the payment order. |
| fraudlabspro_id | string | Optional. Unique transaction ID generated by the Fraud Check API. |
Merchants can call this API immediately after receiving the payment gateway response, ensuring that the payment outcome is accurately recorded.
Real-Time Notifications
FraudLabs Pro also allows merchants to configure notification settings within the Merchant Area > Settings > General page. The payment gateway sends notifications to alert merchants when it declines a high-risk transaction. In addition, merchants can decide to add the customer to either blacklist or watchlist or no action (-) in the notification settings configuration.
This capability helps merchants:
- Investigate suspicious payment attempts
- Monitor potential fraud patterns
- Take additional actions such as blocking users or reviewing accounts
By combining fraud screening with payment feedback and real-time alerts, merchants gain a more comprehensive fraud management workflow.
Conclusion
The FraudLabs Pro Payment API adds an important layer of intelligence to fraud detection. By reporting final payment outcomes, merchants help the system continuously improve its ability to detect fraudulent behavior.
Integrating the Feedback Payment API is simple, yet the impact on fraud prevention can be significant. With better insights into real payment results, businesses can reduce fraud risk, improve decision accuracy and build a safer payment environment for their customers.
