Payments fraud, end to end.

The 90-day playbook: thresholds, escalation timeline, the five most common chargeback root causes, and when to bring in help.

The combined fraud-and-dispute ratio, the 1.5% Excessive threshold (since April 2026), exit criteria, and how VAMP differs from ECM.

The five rule categories that matter, real syntax for each, the Review-mode backtest workflow, and the two rules that always false-positive.

The chargeback no filter can stop: what first-party misuse is, when to fight vs. refund, the evidence that wins representment, and how to prevent and intercept it.

Why Stripe blocked a payment "due to a high risk of fraud," how to find the exact reason in the charge outcome, and how to let real customers through without disabling protection.
