# Data Analyzer Agent - N8N Workflow
|
|
|
|
## Overview
|
|
This directory contains the N8N workflow configuration for the Data Analyzer Agent, which processes uploaded files (CSV, Excel, PDF) and provides intelligent data analysis.
|
|
|
|
## Workflow Files
|
|
- `workflow.json` - Production workflow for N8N import
|
|
- `workflow_dev.json` - Development/testing version (optional)
|
|
- `workflow_backup.json` - Backup version for disaster recovery
|
|
|
|
## Webhook Configuration
|
|
- **Webhook URL**: Configured via `N8N_WEBHOOK_DATA_ANALYZER` environment variable
|
|
- **HTTP Method**: POST
|
|
- **Expected Data Format**:
|
|
```json
|
|
{
|
|
"file_name": "data.csv",
|
|
"file_content": "base64_encoded_content",
|
|
"analysis_type": "statistical",
|
|
"user_request": "Analyze sales trends"
|
|
}
|
|
```
|
|
|
|
## Setup Instructions
|
|
|
|
### 1. Import Workflow to N8N
|
|
1. Open your N8N instance
|
|
2. Click "Import from File" or "Import from URL"
|
|
3. Upload the `workflow.json` file
|
|
4. Configure credentials (OpenAI API key, etc.)
|
|
5. Activate the workflow
|
|
|
|
### 2. Configure Webhook URL
|
|
1. Copy the webhook URL from N8N
|
|
2. Set environment variable: `N8N_WEBHOOK_DATA_ANALYZER=https://your-n8n.com/webhook/data-analyzer`
|
|
3. Restart your Django application
|
|
|
|
### 3. Test the Workflow
|
|
```bash
|
|
# Test via Django application
|
|
python manage.py test_webhook data_analyzer
|
|
|
|
# Or test directly via curl
|
|
curl -X POST https://your-n8n.com/webhook/data-analyzer \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"file_name":"test.csv","file_content":"dGVzdA==","analysis_type":"basic"}'
|
|
```
|
|
|
|
## Workflow Components
|
|
- **Webhook Node**: Receives requests from Django application
|
|
- **AI Processing**: Uses OpenAI GPT-4 for data analysis
|
|
- **Response Node**: Returns structured analysis results
|
|
- **Error Handling**: Manages failures and timeouts
|
|
|
|
## Expected Response Format
|
|
```json
|
|
{
|
|
"success": true,
|
|
"analysis": {
|
|
"summary": "Data analysis summary",
|
|
"insights": ["Key insight 1", "Key insight 2"],
|
|
"recommendations": ["Recommendation 1", "Recommendation 2"],
|
|
"charts": [{"type": "bar", "data": {...}}]
|
|
},
|
|
"processing_time": 1.5
|
|
}
|
|
```
|
|
|
|
## Troubleshooting
|
|
- **Webhook not responding**: Check N8N workflow is active and URL is correct
|
|
- **Authentication errors**: Verify OpenAI API credentials in N8N
|
|
- **Timeout issues**: Increase workflow timeout settings for large files
|
|
- **Rate limiting**: Monitor OpenAI API usage limits
|
|
|
|
## Maintenance
|
|
- Regularly backup workflow configurations
|
|
- Monitor workflow execution logs in N8N
|
|
- Update AI prompts based on user feedback
|
|
- Scale webhook handling based on usage patterns |
