Validate customs clearance documents with Claude AI, Google Drive and Slack

Description

This workflow automates pre-dispatch customs document validation for international shipments. It ingests shipping document packages, extracts content from each file, uses Claude AI to cross-validate all documents for consistency, regulatory compliance, and HS code accuracy, then flags errors before goods are dispatched — preventing costly delays, fines, and rejected shipments at the border.

How it works

Trigger — Webhook submission or watched Drive/S3 folder when new shipment docs are uploaded
Register Shipment — Assigns shipment case ID, normalises metadata from payload
Fetch Document Files — Downloads each document from Google Drive or URL
Extract Text Content — Parses PDF/DOCX text from all documents
Classify Document Types — Identifies invoice, packing list, bill of lading, COO, etc.
Cross-Document Consistency Check — Detects mismatches across documents (values, weights, quantities)
AI Compliance Validation — Claude AI validates each doc against destination country rules
Aggregate Findings — Merges per-document results into a shipment-level report
Route by Risk Level — Branches on CLEAR / HOLD / REJECT
Notify Logistics Team — Slack alert with error summary and action items
Email Exporter Report — Detailed validation report with fix instructions
Update Shipment Tracker — Writes status back to Airtable / Google Sheets
Create Compliance Ticket — Opens Jira issue for HOLD or REJECT shipments
Return API Response — Structured JSON result to caller or TMS integration
