Step 5: Configure NMI Risk Settings

For payments made with a card saved to a shopper’s account, Bolt does not transmit CVV match data to processors. To configure risk settings so the lack of this data does not trigger auto-declines:

Use the NMI guide CVV Settings to allow transactions without CVV matches.

With Fraud Protection

Bolt’s fraud detection engine uses advanced risk signals to protect your business from fraud. Bolt Checkout does not require shoppers to enter a billing address, so the Address Verification System (AVS) mismatch settings may trigger automatic declines on transactions from real shoppers with an otherwise low risk score.

Use the NMI guide on AVS settings to allow all transactions where the shipping and billing address do not match.

Without Fraud Protection

Contact your fraud solutions provider to inform them that payments transmitted via this processor will not provide CVV match information.

Step 4: Set Up Chargeback Notifications

Set up your communication preferences in NMI to receive digital notifications for new chargebacks. This ensures that you have enough time to submit the dispute and respond with evidence.

Chargeback Handling

  • With Fraud Protection: NMI supports manual dispute submissions.
  • Without Fraud Protection: Follow NMI’s chargebacks handling process.
