What this workflow does?

This is a n8n Taxi Service Workflow demo. It is the core node for Taxi Service. It will receive message from the Call Center Workflow, handling the QA from the caller, and pass to each of the Taxi Service Provider Workflow to process the estimation.

How it works

• The Flow Trigger node will wait for the message from Call Center or other Sub-workflow.
• When message is received, it will first check for the matching Service from the PostgreSQL database.
• If no service or service is inactive, output Error.
• Next, always reset the Session Data in Cache, with channel_no set to taxi
• Next, delete the previous Route Data in Cache
• Trigger a AI Agent to process the fare estimation question to create the Route Data
• Use the Google Map Route API to calculate the distance.
• Repeat until created the route data, then pass to all the Taxi Service Provider for an estimation.
