Airline Perseuss External Referral Check

Perseuss is an airline-specific risk mitigation system. You can call Perseuss and receive a risk score for the transaction, which affects the Adyen risk score.

Brazil CPF Check

The Cadastro de Pessoas Físicas (CPF) is the national persons registry in Brazil. For transactions made with a card that was issued in Brazil, you can check if the details that the shopper provided match the data in the CPF database.

You have to include the parameters holderName, billingAddress, and telephoneNumber in the payment request for this check to work.

There are sub-checks associated with this risk rule. Each allows for an individually configurable score to be added to the transaction score if the rule matches.

The checks are as follows:

  • Transaction amount: You enter a transaction amount in minor units above which payments will be checked against the CPF database.
  • CPF number is not valid: The shopper-submitted CPF is not a valid CPF number.
  • CPF database is not available: The database is temporarily not available, or the request to the third party server timed out.
  • Name does not match: The name associated with the transaction does not match with the name in the CPF database. 
  • Address does not match: The billing address associated with the transaction does not match that in the CPF database.
  • Phone does not match: The phone number associated with the transaction does not match that in the CPF database. 

German SCHUFA Check

SCHUFA (Schutzgemeinschaft für allgemeine Kreditsicherung) is a German private credit bureau. Adyen's risk management lets you check shoppers credentials against the SCHUFA database for German SEPA transactions.

You have to include the parameters billingAddress, dateOfBirth, and shopperName in the payment request for this check to work.

The risk rule has filters that let you target high-value/high-risk transactions:

  • Transaction amount: You enter a transaction amount in minor units above which SEPA payments will be checked against the SCHUFA database.

  • SCHUFA thresholds: You specify two separate thresholds and assign a risk score for each; one for moderate risk and one for high risk.

When the rule triggers, SCHUFA responds with a value associated with the shopper. When both of the thresholds you set are applicable based on the SCHUFA response, the highest of these scores is used for the risk rule.

For example, when you set moderate risk to A with a risk score of 10, and set high risk to E with a risk score of 20, a response of:

  • A or above returns a risk score of 10. This is the base rule setting.
  • E or above returns a risk score of 20. This is the base rule setting.
  • C returns a risk score of 10.
  • M returns a risk score of 20.

External Risk Score (Generic)

This check takes a score submitted in the payment request and uses it to change the Adyen risk score. Use this if you are using a separate risk system. The external score must be calculated before the payment request is submitted (pre-auth).

You can set values to receive in the external risk score and the corresponding value of the rule should be added to the Adyen risk score. For example, an external value of 5 may add 40 to the Adyen risk score. This setting is an exact match.
