Answer wealth management portfolio questions with Google Sheets, live prices and Google Gemini

(Wealth Management) Client Question → Instant Answer Assistant

(n8n + Google Sheets + AI + API)

This workflow allows users to ask portfolio-related questions in a simple format (C001: your question). It validates the input, fetches client data and holdings from Google Sheets, retrieves live market prices via API, calculates portfolio performance and generates a short AI-powered response.

Quick Implementation Steps

1. Connect Google Sheets (clients, holdings, interaction_logs)
2. Configure Get Live Prices API endpoint
3. Add credentials for Generate AI Answer (Google Gemini)
4. Ensure input format: C001: your question
5. Run test cases (valid + invalid inputs)

What It Does

This workflow acts as an intelligent financial assistant that responds to client portfolio queries in real time. It starts by receiving a chat message through the When chat message received node and processes it using Parse Client Message to extract the client ID and question.

Once validated, it retrieves client details using Get Client Profile and portfolio holdings via Get Client Holdings. It then fetches live stock prices through the Get Live Prices API and merges all data using Merge Portfolio Data to compute metrics like invested value, current value, profit/loss and returns.

Finally, the workflow builds a structured prompt in Build AI Prompt and generates a concise response using Generate AI Answer, ensuring the reply is accurate, controlled and based only on available data.

Who Can Use This Workflow

• Financial advisors managing multiple client portfolios
• Wealth management platforms
• Fintech developers building AI-driven assistants
• Anyone looking to automate portfolio Q&A workflows

Requirements

• n8n (self-hosted or cloud)
• Google Sheets account with:

• holdings sheet
• interaction_logs sheet
• Live price API endpoint (used in Get Live Prices)
• Google Gemini API credentials (used in Generate AI Answer)

How It Works & Setup Guide

1. Trigger & Input Parsing

• When chat message received receives input
• Parse Client Message extracts:
• client_id
• question
• IF Valid Input? validates format

If invalid:

• Build Invalid Input Response
• Log Invalid Input
• Return Invalid Response

2. Client & Holdings Lookup

• Get Client Profile fetches client details
• IF Client Found? ensures existence
• Get Client Holdings retrieves holdings
• Prepare Symbols extracts stock symbols
• IF Holdings Found? validates data

Failure handling:

• Build Client Not Found Response
• Build No Holdings Response

3. Market Data Fetching

• Get Live Prices calls external API
• Normalize Price Response standardizes output
• IF Price API Worked? validates API success

Failure handling:

• Build API Failed Response

4. Portfolio Calculation

• Merge Portfolio Data computes:
• Invested amount
• Current value
• P&L
• Return %
• Best performer
• Weakest performer
• Missing prices

5. Market Context (Optional Enhancement)

• Get Market Context
• Attach Market Context

Adds optional insights like:

• Nifty/Sensex movement
• Market tone

6. AI Response Generation

• Build AI Prompt creates structured prompt
• Generate AI Answer generates response
• Extract AI Answer extracts clean reply

7. Final Output

Final response includes:

• Client ID
• Question
• AI reply
• Status
• Timestamp

How To Customize Nodes

• Parse Client Message
• Modify input format rules
• Get Live Prices
• Replace with another API (Alpha Vantage, Twelve Data, etc.)
• Merge Portfolio Data
• Add more financial metrics (CAGR, allocation %, etc.)
• Build AI Prompt
• Change tone (formal, advisory, aggressive)
• Generate AI Answer
• Replace Gemini with Hugging Face / OpenAI models

Add-Ons (Enhancements)

• Add Slack notifications for responses
• Save AI replies to CRM
• Add email delivery for clients
• Implement caching for price API
• Add retry logic for API failures
• Support multi-client batch processing

Use Case Examples

1. Client asks: “C001: How is my portfolio performing?”
2. Advisor checks: “C002: Which stock is my top performer?”
3. User queries: “C003: Why is my portfolio down?”
4. Daily automated portfolio summary generation
5. Integration with chatbot for real-time advisory

There can be many more use cases depending on how this workflow is extended.

Troubleshooting Guide

Issue	Possible Cause	Solution
Invalid input error	Wrong format	Use C001: your question
Client not found	Missing in sheet	Check clients sheet
No holdings found	Empty data	Verify holdings sheet
API failed	Endpoint issue	Check API URL or timeout
AI reply empty	Model issue	Verify API credentials
Incorrect calculations	Missing price data	Check API response
