AI Taxi Booking Auto-Cancellation & Notification (Prod-Ready)

This production-ready n8n workflow serves as the backend for a taxi booking support chatbot. Triggered every 5 minutes via Schedule Trigger, it queries a Postgres database for OPEN or HOLD bookings older than 10 minutes. For qualifying bookings, it updates the status to CANCELLED, deletes the associated Google Calendar event, and optionally uses an AI Agent to generate a personalized, multi-language reply message to the user.

Key features include scaling design for n8n Queue mode, customizable expired booking actions, and multi-language support based on booking language. It integrates Schedule Trigger, Postgres, AI Agent, Google Calendar, Execute Sub-workflow, If/Switch nodes, Code node, and Set node for robust logic handling.

Benefits: Saves manual intervention in after-sales processes, ensures timely cancellations to free resources, enhances user experience with automated notifications, and scales for high-volume production environments. Use cases: Taxi/ride-sharing services, booking systems needing auto-expiry handling, call center backends integrated with chatbots.
