// fraud scoring
Score every order before it ships.
Six signal classes compose the fraud score for every order — weighted, calibrated to your store's actual chargeback history. The score lands in fraud_scores; high scores route to manual review, very high scores auto-cancel.

VPN / proxy / residential, geolocation distance from billing address, prior abuse history.
velocity
w=0.22
Order rate from this email / card / address — bursts get scored, distributed attacks too.
email_reputation
w=0.14
Domain age, disposable / catchall flag, prior chargeback history across the merchant network.
card_history
w=0.18
BIN risk, country mismatch, prior dispute filings, issuer-side flags.
behavioral
w=0.12

// pre-dispute alerts
Refund before the chargeback files.
Issuers send pre-dispute warnings — Ethoca, Verifi CDRN, Visa RDR. Magistry listens for them and acts inside the response window, before the dispute becomes a chargeback you have to fight.
Ethoca
Mastercard
Inbound issuer-side alert when a customer files a dispute. We auto-refund or counter within the response window, before the chargeback lands.
Verifi CDRN
Visa
Consumer Dispute Resolution Network — early warning from the issuer. Same auto-route: refund inside window, or queue evidence for rebuttal.
Visa RDR
Visa
Rapid Dispute Resolution. Pre-authorized refund rules fire automatically when criteria match — never wait for a human to click.
Every inbound alert lands in dispute_alerts with vendor, reason code, response window, and routing decision — auto-refund, auto-rebut, or human review. Same audit plane shape as every other Magistry write.
// tracking watcher
Order-Not-Received prevention.
The most common chargeback reason is one you can prevent. Tracking Watcher monitors fulfillment events on every shipment — when an order stalls past your store's threshold, the customer gets a proactive update before they ever doubt the package is coming.
// what it watches
- Carrier last-ping time vs your stall threshold per lane.
- Customs holds, last-mile failures, return-to-sender events.
- Address mismatch warnings caught before the package leaves.
// what it does
- →Drafts proactive customer email — language-gated, brand-voice held.
- →Sets policy-defined trace SLA — refund or replace if no movement by date.
- →Logs a tracking_watches row — future dispute gets that history attached as evidence.

// evidence + rebuttal
The packet writes itself.
Once a dispute lands, Magistry walks the order, the fulfillment history, the customer comms thread, and the policy chunks — and assembles the rebuttal packet to the issuer's accepted spec. LLM drafts; Reply Judge scores; you approve or auto-submit.
Per-reason-code assembly
Each dispute reason code — fraud, product-not-received, not-as-described — has its own evidence template. Magistry walks the order, the fulfillment, the customer-comms thread, and fills it.
Visa CE 3.0 auto-detect
Compelling Evidence 3.0 — if the customer has two prior undisputed transactions on the same merchant, we surface the data Visa needs to dismiss the dispute on technicality.
LLM rebuttal generation
Rebuttal letter drafted from the evidence pack — fact-grounded, citation-rich, formatted to the issuer's accepted spec. Reply Judge scores before submit.
Submission to processor
Shopify Payments, Stripe, or PayPal — we ship the evidence pack directly through the dispute API on the correct portal, never a manual upload.
// submission targets
One workflow. Three processors.
Whatever processes your payments, Magistry submits the dispute response through the right API — with idempotency, retries, and event-stream parsing into dispute_events for live status.
Shopify Payments
Disputes API (Admin GraphQL)
Direct submission of evidence packs. Status events stream back into dispute_events for live tracking inside the dashboard.
Stripe
Disputes + Radar API
Programmatic dispute updates with structured evidence fields. Radar rules tuned by fraud_scores feedback loop.
PayPal
Disputes API v1
Buyer-protection cases handled the same shape. PayPal's slower API gets idempotent retries and timeout-safe writes.
“We won 71% of our friendly-fraud disputes the first month after we wired DisputeShield up. The Visa CE 3.0 auto-detection alone closed cases we used to write off.”

Stop fighting yesterday's chargebacks.
