7. Automated Dispute Response (Reflex)

Autopilot Functionality

  • Reflex automatically responds to disputes when enabled
  • You can disable autopilot globally or for specific disputes
  • Evidence submission typically occurs within 60 seconds of dispute creation

Your Responsibilities

  • Ensure your fulfillment evidence is accurate and complete
  • Review dispute outcomes and provide feedback
  • Maintain accurate customer records and delivery proof
  • Comply with your payment platform's dispute policies and procedures

No Guarantee of Outcome

  • Reflex does not guarantee that disputes will be won
  • Win probability estimates are for informational purposes only
  • Final dispute decisions are made by payment processors and card networks
  • We are not liable for lost disputes or associated chargebacks

8. Refund Abuse Detection (Sentinel)

Scoring

  • Sentinel scores refund requests 0-100 based on hashed device, IP, card, and email signals contributed by every Sentinel merchant
  • No raw personal data leaves any merchant, only hashed signals are shared
  • Score is advisory only; the merchant makes the final refund decision

Customer Proof Requests

  • Proof-request emails are an optional, merchant-initiated feature, off by default
  • Each merchant must explicitly enable the feature and confirm they have added proof-request language to their posted return policy
  • Proof requests are pre-agreement: they ask the customer to provide context before the merchant decides whether to refund, they do not delay a refund the merchant has already approved
  • Proof requests are restricted to cardholders in US, UK, Canada, Australia, New Zealand, and Ireland at launch
  • Proof requests are skipped for subscription transactions and for EU/UK cardholders within the 14-day statutory withdrawal window
  • Only one proof request may be sent per refund request
  • Customer non-response does not trigger an automatic decline, the merchant reviews and decides
