Fraud Analytics

Requires Growth tier or above
The Fraud page identifies suspicious patterns in your transaction data.

​
Metrics

  • Fraud-Related Declines — Transactions declined for fraud reasons (stolen card, security violation)
  • Fraud Rate — Fraud declines / total transactions
  • Avg Fraud Amount — Average amount of fraud-related declines
  • Unique Cards Flagged — Number of distinct cards with fraud declines

​
Fraud by Decline Reason

Breakdown of fraud-specific decline reasons with counts and amounts. Common fraud reasons:
  • Stolen card / pick up card
  • Security violation
  • Suspected fraud
  • CVV mismatch (potential card testing)

​
Card Brand Fraud Rates

Fraud decline rates by card network. Helps identify if a specific processor or card brand has elevated risk.

​
High-Value Declines

The largest declined transactions by amount. High-value declines deserve attention — they may be legitimate customers hitting card limits, or they may be fraud attempts testing large amounts.

​
What This Page Does NOT Do

This page analyzes historical decline data. It does not:
  • Block transactions in real-time (that’s your NMI gateway’s job)
  • File fraud reports with card networks
  • Provide chargeback management (see Disputes page)
Think of it as a diagnostic tool — it shows you where fraud is happening so you can adjust your gateway rules or follow up with customers.
