"content": "## Validate extracted quote items against a trusted catalog\n\n### Who this is for\nOperations and automation teams that use AI or OCR to extract parts, labor, and travel data before preparing a quote. The workflow prevents extracted references or claimed prices from becoming trusted totals without checks.\n\n### What it does\nA POST webhook receives a synthetic request. The first Code node validates request IDs, text length, labor hours, booleans, item count, reference format, and quantity limits. Valid candidates move to a fixed synthetic catalog. Claimed unit prices are ignored; only exact catalog references supply prices. Calculations use integer cents for materials, margin, labor, travel, VAT, and total.\n\nThe workflow returns three explicit outcomes:\n- `200 QUOTABLE` when every item matches.\n- `422 NEEDS_REVIEW` with no totals when any reference is missing.\n- `400 REJECTED` when input validation fails.\n\n### How to set up\n1. Import the workflow and keep it inactive.\n2. Add webhook authentication before accepting external traffic.\n3. Replace the synthetic catalog and rates with an approved data source and documented rules.\n4. Test accepted, missing-reference, malicious-price, and invalid-quantity cases.\n5. Add human approval before any quote is sent.\n\n### Requirements and customization\nUses only built-in Webhook, Code, If, and Respond to Webhook nodes. No credentials, external APIs, customer data, or LLM calls are included. Customize the input contract, catalog lookup, currency, tax, rounding, and response codes. Reproducible test evidence: [setup and cases](https://automation-note.com/articles/n8n-swiss-quote-prototype/).",
