Hub: Fraud Signals and Risk Patterns

Quick Answer

Low authorization rate means too many attempted payments fail before they become approved transactions. The cause can be bad traffic, issuer mismatch, attack pressure, or controls that are too broad.

What Stripe Is Likely Comparing

  • authorization rate by source, geography, and device
  • issuer response patterns
  • fraud-rule changes vs approval movement

Most Common Root Causes

  • low-quality or mismatched traffic
  • bot or testing pressure
  • authentication or rule settings that block too much good traffic

Evidence Stripe Will Weight Most

  • approval trends by cohort
  • issuer and decline-code patterns
  • before-and-after results from rule adjustments

Operational Fix Sequence

  1. Separate quality problem from control problem.
  2. Isolate weak traffic sources.
  3. Retune rules only after traffic quality is understood.
