Ready for 3.0Ready for 3.0. This template uses no nodes that n8n 3.0 removes. No removed nodes, versions or helpers found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 23 nodes and runs on a schedule (every day at 02:00). Along the way it connects OpenAI Chat Model and Postgres.
How it runs
Trigger: On a schedule (every day at 02:00).
- Workflow Configuration (Edit Fields (Set)): sets 9 fields: claimsApiUrl, excessivePayoutThreshold, reserveVarianceThreshold…
- Fetch Historical Claims Data (HTTP Request): calls an HTTP API
- Detect Cost Leakage Anomalies (Code): runs custom JavaScript code
- Check If Leakage Detected (If): checks a condition and branches into true / false
- AI Root Cause Classifier (AI Agent): runs an AI agent, with model: OpenAI GPT-; 1 tool (Calculator); output parser: Classification Output Parser
- Split Anomalies Into Items (Split Out): splits a list into separate items
- No Leakage Found (Edit Fields (Set)): sets 3 fields: status, analysisDate, message
- Generate Corrective Adjustments (Code): runs custom JavaScript code
- Fetch Vendor History (HTTP Request): calls an HTTP API
- Fetch Policy Rules (HTTP Request): calls an HTTP API
…plus 9 more steps. See the full node list below.

Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
