n8n Contract Risk Triage: GPT-4o + Slack + Gmail Automation

GPT-4o contract risk triage that escalates in Slack and emails a clear summary—fully automated in n8n

This n8n workflow receives contract submissions, extracts and cleans contract text via a document-parsing/OCR API, analyzes clause-level risk with GPT-4o, then automatically escalates high-risk cases to Slack and emails a risk summary to the requester via Gmail. Results are logged to Google Sheets and returned to the original webhook caller.

What this workflow does

• Receives a contract through a POST webhook with fields like contract_name and requester_email, plus the document reference expected by your parser.
• Extracts contract text by sending the document to an external document-parsing/OCR HTTP Request API to obtain clean text.
• Performs clause risk analysis using OpenAI (GPT-4o), returning structured JSON including overall risk, flagged clauses, missing clauses, and a summary.
• Triages based on overall risk using an if check for “high risk.”
• Escalates high-risk reviews by posting a Slack message with the contract name and top issues.
• Notifies requesters for non-high-risk cases by sending a Gmail email containing the overall risk and summary.
• Logs everything by appending the review output to a Google Sheets “Contract Register” and responding to the webhook caller with the overall risk value.

Use cases

• Contract Intake in a portal/CLM/email-to-webhook flow that needs instant contract risk triage.
• Legal ops teams who want Slack escalation only when risk is high, reducing noise.
• SaaS operators needing an auditable Contract Register for every review outcome.

Technical details

• Nodes/stack: webhook, HTTP Request (doc-parsing/OCR API), OpenAI (GPT-4o), if, Slack, Gmail, Google Sheets (Contract Register), sticky note.
• Setup highlights: configure the intake webhook URL; update HTTP Request node with your parser endpoint/auth headers; add OpenAI credentials and ensure gpt-4o is available.
