Introduction

Although 3-D Secure is now mandatory for online transactions, SCA regulations allow to skip 3-D Secure altogether in some cases. Checking the requirements for that adds complexity to your integration, especially when you need to weight customer experience and conversion rate against Fraud Prevention.

Therefore, we are happy to offer you the Exemption Engine feature. It implements this process by automatically:

• Scanning incoming transactions, rolling out or skipping 3-D Secure appropriately.
• Steering the flow to Soft Decline and/or challenge/frictionless flow when applicable.

You can keep sending all your flow to one account, as the Exemption Engine will automatically filter your transactions which are not eligible for exemptions.

The following exemptions are in scope:

• Low amount transactions: For transactions below 30€ (or equivalent in another currency). However, SCA is applicable if your customers make either
  
  • Five consecutive transactions without authentication
    Or
  • A transaction higher than 100€
    
    In cases like these, the issuer refuses the exemption and we will reinitiate SCA
    
    
• Acquirer Transaction Risk Analysis (TRA): For transactions considered low fraud risk. As your acquirer is liable and overlooks the overall portfolio of the transactions (transaction value, fraud rate), it grants an exemption or not. Contact your acquirer for details

The following are not in scope:

• Transactions for payment methods:
  JCB
  Diners Club
• For transactions you send with parameter cardPaymentMethodSpecificInput.threeDSecure.challengeIndicator (i.e. for recurring payments).
• Transactions above 500€.
• Transactions out of SCA scope.

Based on the overall picture, our platform will automatically skip or roll-out 3-D Secure, steering the overall payment flow accordingly.

Understand payment flow

Our Exemption Engine is available for or all our integration modes and blends in seamlessly in the payment flow.

1. You send a CreatePayment/CreateHostedCheckout request to our platform, including at least the mandatory 3-D Secure and as many Fraud Prevention properties as possible
2. Your Fraud Prevention module calculates the Global Fraud Score and checks whether the transaction is applicable for the Exemption Engine flow:
   a. If any of the criteria is met, the flow continues at 3
   b. If not, the flow continues at 4
3. We submit the actual financial transaction to the acquirer to process it. We receive the transaction result. The flow continues at 7
4. We submit the actual financial transaction to the acquirer with a preference for frictionless flow. If the issuer does not accept the frictionless flow, we will automatically recover the transaction via Soft Decline
5. We receive the transaction result
6. We redirect your customer to your returnUrl
7. You request the transaction result from our platform via GetPayment or receive the result via webhooks
8. If the transaction was successful, you can deliver the goods / service
