n8n Google Drive Contract Risk with Groq, Salesforce & Slack

Automatically assess contract risk as soon as a PDF hits Google Drive—then log it in Salesforce and notify Slack

This n8n workflow watches a specific Google Drive folder for new contract PDFs, extracts and cleans the text, uses Groq-hosted LLMs to identify key clauses and evaluate risk, and then writes an overall risk summary to a Salesforce custom object while posting a concise alert to Slack.

What this workflow does

• Monitors Google Drive for newly created files in your chosen folder.
• Validates the file type (only processes PDF contracts), downloads it, and derives a contract name from the filename.
• Extracts contract text from the PDF, normalizes whitespace, and splits the content into smaller chunks for more reliable LLM processing.
• Extracts and classifies clauses using a Groq LLM, parsing model output into structured JSON.
• Performs risk analysis with a second Groq LLM run to assign risk levels, identify issues, and recommend improvements, generating an overall risk report (overall risk, summary, top risks, and recommendations).
• Syncs results to Salesforce by searching for an existing Contract_AI__c record by contract name, creating it if missing, and updating it with the final report fields.
• Notifies your team in Slack with the overall risk level, summary, and the top risk plus recommendation.

Use cases

• Legal ops teams reviewing incoming vendor or customer contracts uploaded to Google Drive.
• Automation engineers needing an n8n workflow that links LLM clause extraction, risk scoring, Salesforce record updates, and Slack notifications.
• SaaS operators building a contract intake pipeline for faster decision-making.
