Signifyd

Integrate Signifyd fraud and risk management with Juspay Hyperswitch to automate fraud decisions and protect against chargeback liability.

Signifyd connects to Hyperswitch as a FraudAndRiskManagementProvider. It provides AI-driven commerce protection with guaranteed fraud liability coverage — Signifyd takes on chargeback liability for orders it approves. Signifyd is not a payment processor; it evaluates orders independently of payment authorization.

Authentication

Signifyd uses HeaderKey authentication — a single API key sent as a Bearer token on every request.

Credential	Description
API Key	Bearer token issued by Signifyd. Found in your Signifyd merchant portal under API settings.

FRM Flows

Signifyd participates in the following Hyperswitch FRM flows:

Flow	Description
Sale	Pre-authorization fraud check on the payment attempt
Checkout	Fraud evaluation at checkout, before payment is submitted
Transaction	Post-authorization evaluation of a completed transaction
Fulfillment	Signal to Signifyd that an order has been fulfilled (triggers liability shift)
RecordReturn	Notify Signifyd of a return or refund on a previously approved order

Webhook Events

Signifyd sends decision updates via webhook. Hyperswitch handles HMAC-SHA256 signature verification using the API key.

Common Failure Modes

Decision not returned Symptom: FRM evaluation times out or returns no decision. Fix: Check Signifyd's merchant portal for order status. Ensure the order details (email, address, line items) are complete — incomplete orders are often held or declined by Signifyd.

Liability shift not applied Symptom: Signifyd approves the order but chargeback liability is not shifted. Fix: Verify the Fulfillment flow is being called after shipment. Liability shift typically requires a fulfillment signal.
