n8n Cold-Chain Recall Risk Webhook Workflow with Anthropic Email

Predictive cold-chain recall alerts—powered by Anthropic Claude

This n8n workflow listens for cold-chain temperature excursion events via a webhook, enriches each batch with shipment route history from your logistics provider, and uses Anthropic Claude (claude-sonnet-4) to predict batch compromise risk—then emails a predictive recall alert to quality and operations.

What this workflow does

• Receives IoT excursion data: Handles an incoming POST webhook payload containing a batch ID, shipment ID, and timestamped temperature/geo sensor readings from cold-chain devices.
• Enriches with logistics history: Calls your logistics provider API (by shipment ID) to fetch route and handling history.
• Calculates risk features: Computes actionable signals such as safe temperature range, excursion count, maximum deviation, minutes outside range, and a route risk score.
• Calls Anthropic Claude for prediction: Sends the engineered features to claude-sonnet-4 to return JSON including compromise probability, risk level, recommended action, and brief reasoning.
• Generates and sends a recall report: Formats a predictive recall alert (with a rule-based fallback if JSON parsing fails) and emails it to configured quality/ops recipients. The email subject includes the batch ID and risk level.

Use cases

• Quality teams need rapid escalation when cold-chain temperature excursions occur.
• Operations want shipment-specific risk context (route + handling history) before initiating recall steps.
• SaaS operators running IoT logistics monitoring can automate recall triage with Anthropic-powered risk scoring.

Technical details

• n8n nodes / components: Webhook trigger, HTTP Request to logistics API, Code (risk feature engineering + parsing), Wait (workflow control), Email Send (alert delivery), plus supporting Code/Sticky Note elements.
• Webhook endpoint: Configure your IoT gateway/app to POST excursion payloads to /cold-chain-excursion.
• Integrations: Logistics provider API (route-history), Anthropic API for claude-sonnet-4, and email delivery to quality/operations stakeholders.
