Why This Happens

Stripe Radar uses machine learning to score every transaction for fraud risk. When risk scores exceed your configured threshold, transactions are automatically blocked. False positives — legitimate transactions incorrectly flagged — can result from new customer patterns, international orders, high-value purchases, or overly aggressive custom Radar rules.

Example Notification

"Multiple transactions were blocked by Stripe Radar due to elevated risk scores. Review your Radar settings and blocked payments in the Dashboard."
