Automate Transaction Monitoring with n8n & AI Alerts

Protect your business from financial risks with this intelligent n8n workflow that automatically monitors daily transactions in Google Sheets, detects suspicious activity using AI-powered analysis, and sends instant email alerts when high-value or unusual patterns are identified.

What This Workflow Does

This comprehensive transaction monitoring system fetches daily transaction records from your Google Sheets database and processes only current-day entries for real-time oversight. The workflow automatically cleans your data by updating any missing dates, ensuring consistent and accurate transaction records.

The system calculates critical transaction metrics including total transaction count, cumulative transaction amounts, and identifies high-value transactions exceeding the configurable ₹50,000 threshold. When suspicious activity patterns are detected based on your defined risk parameters, the workflow leverages Groq AI to generate intelligent risk analysis explanations.

Upon detecting anomalies, the workflow automatically updates transaction records with AI-generated risk assessments and sends immediate Gmail alerts to your finance team, enabling rapid response to potential threats.

Use Cases

• Finance teams monitoring daily transaction volumes for fraud detection
• E-commerce businesses tracking high-value payment anomalies
• Financial institutions implementing automated compliance monitoring
• Accounting departments ensuring transaction data integrity
• Risk management teams requiring real-time suspicious activity alerts
