Payment Fraud Detection and Risk Scoring
Catch fraudulent orders before they become chargebacks. Risk scoring happens automatically as issues arrive.
Trigger
Public Team Issue Properties Updated
Fires when properties on a *public-team* Linear issue change (status, assignee, priority, labels, etc.). For private teams (lock icon in Linear's sidebar) use `LINEAR_PRIVATE_TEAM_ISSUE_PROPERTIES_UPDATED`.
Action
User Risk API
Tool to return a risk assessment for a user based on ip signals for fraud prevention. use after initial ip checks to decide whether to bypass or require captcha challenges.
Why this helps
Founder can't manually review every payment for fraud. Suspicious transactions get mixed into normal refund requests, creating security gaps.
- Flag high-risk transactions automatically using IP-based signals
- Prevent chargebacks by catching fraud before it costs you
- Reduce manual review burden on your payment team
- Create an audit trail of all risk assessments in Linear
Setup
Build it in a few focused steps.
- 1Connect your Linear workspace and Big Data Cloud fraud detection APIs to Notis.
- 2Create an automation: 'When a payment issue is updated, get a user risk assessment for the customer IP and tag high-risk transactions.'
- 3Select 'Public Team Issue Properties Updated' as your trigger (to catch when payment issues are tagged or escalated).
- 4Set Notis to add risk score as a comment and auto-label high-risk issues for review.
- 5Test by creating a payment issue with a known VPN IP and confirm Notis flags it as suspicious.
Questions about this workflow
What IP signals does risk assessment check?
VPN/proxy usage, geolocation anomalies, device fingerprinting mismatches, hosting provider risk, and historical fraud patterns. Multi-factor risk scoring.
Can this lead to false positives?
It assigns a risk score, not a block. Legitimate VPN users might score high. Use the score as a guide for review, not an absolute rule.
How do we handle international transactions?
Notis compares IP location against billing address and shipping address. Geolocation mismatch increases risk. Works globally.
