Import workflow into n8n\n2. Configure credentials:\n - **Anthropic API** \u2014 Claude AI for legal document analysis\n - **Google Drive OAuth** \u2014 Document intake and report storage\n - **Google Sheets OAuth** \u2014 Compliance audit log\n - **Slack OAuth** \u2014 Legal team alerts\n - **SendGrid / SMTP** \u2014 Submitter notification emails\n3. Set your Google Drive folder IDs for intake and output\n4. Configure jurisdiction rules in the AI prompt node\n5. Set mandatory document checklist in the Checklist node\n6. Activate the workflow\n\n### Sample Webhook Payload\n```json\n{\n \"caseId\": \"CASE-2025-0871\",\n \"submitterEmail\": \"agent@realty.com\",\n \"propertyAddress\": \"42 Oak Street, Sydney NSW 2000\",\n \"transactionType\": \"sale\",\n \"jurisdiction\": \"NSW\",\n \"documents\": [\n {\n \"name\": \"Contract of Sale\",\n \"type\": \"contract\",\n \"driveFileId\": \"1aBcDeFgHiJkL\"\n },\n {\n \"name\": \"Title Search\",\n \"type\": \"title\",\n \"driveFileId\": \"2mNoPqRsTuVwX\"\n }\n ]\n}\n```\n\n### Document Types Supported\n- Contract of Sale / Purchase Agreement\n- Certificate of Title / Title Search\n- Vendor Disclosure Statement\n- Section 32 / Vendor Statement\n- Building & Pest Inspection Report\n- Strata Report / Body Corporate Docs\n- Zoning Certificate / Planning Certificate\n- Land Tax Certificate\n- Mortgage / Discharge of Mortgage\n- Lease Agreement / Tenancy Documents\n- Council Rates Notice\n- Smoke Alarm / Safety Certificates\n\n### Features\n- Multi-document batch validation per submission\n- Jurisdiction-aware compliance rules (AU/UK/US configurable)\n- Missing document detection against mandatory checklist\n- Expiry date validation for time-sensitive certificates\n- Critical clause and red-flag detection\n- Automated remediation guidance per issue\n- Full audit trail in Google Sheets\n- PDF validation report stored to Drive\n\n---\n\n**Explore More Automation:** \n[Contact us](https://www.oneclickitsolution.com/contact-us/) to design AI-powered lead nurturing, content engagement, and multi-platform reply workflows tailored to your growth strategy." }, "typeVersion": 1 }, { "id": "5d335b19-7bda-4f94-b31e-b1fc5d097e63", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ 1024, 512 ], "parameters": { "color": 4, "width": 456, "height": 524, "content": "## 1.
