As part of RevenueProtect, Adyen performs fraud checks on each transaction. The outcome of these checks is the fraud score.
There are two types of fraud checks:
- Pre-authorisation checks are performed before the authorisation takes place, such as shopper behavior, referral list checks, and so on.
- Post-authorisation checks include data that is received by issuers, such as AVS data and CVC codes.
If both types of checks together add up to 100 or more, the transaction will have a Received and Refused status.
To check the fraud score for a specific payment, in the Customer Area go to Payments > Search for payments > Fraud Scoring.
You can change the calculation for a fraud score, or disable fraud score criteria in RevenueProtect > Risk Engine Profiles. Take care when changing settings, as if this is done incorrectly you may cause all payments to be refused.
