Automate vehicle insurance claim approvals with OpenAI, OCR and PDF API Hub

This workflow automates the full lifecycle of a vehicle insurance claim — from an incoming Gmail email to a signed, watermarked PDF decision letter delivered back to the claimant.

It monitors Gmail for emails with a PDF claim attachment, deduplicates them against a Google Sheet, parses the claim PDF using PDF API Hub's OCR, evaluates the claim with OpenAI GPT-4o-mini (or a built-in mock evaluator for testing), and routes it to one of three paths:

- Approved — generates a signed approval letter, stamps it APPROVED, uploads to Google Drive, and emails the claimant - Rejected — generates a rejection letter, stamps it REJECTED, uploads to Google Drive, and emails the claimant - Manual Review — notifies your claims adjuster by email for human review

Every claim is logged and tracked in a Google Sheet.
