Sentiment Analysis & CSAT Video AI Agent

Overview

This guide deploys the Sentiment Analysis & CSAT Video AI Agent workflow.

The workflow automatically creates a feedback agent on TruGen and analyzes user sentiment/CSAT after every interaction.

Quick Start: Deployment Flow

This workflow automates setup directly from n8n.

Step 1: n8n Import & Credentials

1. Import the Sentiment Analysis Trugen Updated.json workflow into n8n.
2. Connect credentials for:
   • TruGen AI (agent management API key)
   • Google Sheets (feedback data storage)
   • OpenAI (analysis engine, e.g. GPT-4o-mini)

Before you run it: replace hardcoded values

• In Create a new agent, replace callback_url with your own n8n webhook URL.
• In Save to Google Sheets and Store in Google Sheets, select your own Google Sheet document and tabs.
• Replace any default account-specific values (email/credentials) with your own.

Step 2: Automated Agent Creation

• Find the node "▶️ Click to Start Setup" and execute it.
• This creates the TruGen Feedback Intelligence Agent with predefined sentiment collection instructions.
• The generated Agent Link and metadata are stored in your connected Google Sheet.

Step 3: Webhook & Callback Sync

• Copy your Webhook URL from the n8n Webhook node.
• In TruGen Dashboard, open your new agent Settings.
• Set Callback URL to your n8n webhook URL.
• Set Callback Event to Call Ended.

Workflow Logic

Creation Phase

• A one-time setup that registers the feedback agent on TruGen and prepares the data logging environment.
• Node flow: ▶️ Click to Start Setup -> CustomerSatisfaction Description -> Prepare TruGen Feedback Intelligence Agent -> Create a new agent -> Save Agent Info -> Save to Google Sheets

Feedback Capture

• Users provide voice/video feedback. The agent is configured to capture interactions without bias.
• Trigger path: Webhook (POST call_ended) -> Get conversation details

Intelligence & Storage

After each call:

• The workflow receives callback data through Webhook.
• Full conversation details are fetched.
• AI sentiment analysis runs (CSAT, sentiment, emotions, pain points).
• Structured insights are written to Google Sheets.
• Processing path: AI Agent - Sentiment & CSAT Analysis + Structured Output Parser + 4.1-Mini -> Format for Google Sheets -> Store in Google Sheets

Requirements

• TruGen AI API access
• OpenAI API key (optimized for GPT-4o-mini)
• Google Sheets (pre-formatted template from workflow notes)
• n8n instance

Data Captured in Output

• sentiment, csat_score, confidence
• user_conversation_summary
• key_insights, pain_points, positive_aspects
• resolution_status, emotion_detected

Result

• Automated feedback-agent setup from n8n
• Post-call CSAT and sentiment intelligence
• Structured analytics available in Google Sheets
