Enterprise Automation with N8N: 50+ Workflows at Scale

Building automated workflows for UN-Habitat's global operations

At UN-Habitat, I led the development of a comprehensive automation ecosystem using N8N, creating over 50 interconnected workflows that transformed how our organization handled data processing, communication, and operational tasks across 12 global cities.

Workflow Automation Architecture

The Challenge

UN-Habitat's global operations involved managing vast amounts of data from multiple cities, coordinating between different departments, and ensuring consistent communication across international teams.

Operational Complexity

Our organization faced several automation challenges:

Data silos: Information scattered across multiple systems
Manual bottlenecks: Time-consuming repetitive processes
Communication gaps: Inconsistent updates between teams
Scale requirements: Operations across 12 global cities
Integration needs: Connecting diverse tools and platforms

Manual processes were creating bottlenecks and inconsistencies that impacted our mission-critical work.

Key Workflow Examples

1. Multi-City Data Synchronization

// N8N JavaScript Function Node
const cityData = $input.all();
const processedData = [];

for (const city of cityData) {
  const normalized = {
    city_id: city.json.id,
    timestamp: new Date().toISOString(),
    indicators: {
      population: parseInt(city.json.population),
      gdp: parseFloat(city.json.gdp),
      sustainability_index: city.json.sustainability_score
    },
    source: city.json.data_source
  };
  
  // Validate data integrity
  if (normalized.indicators.population > 0 && 
      normalized.indicators.gdp > 0) {
    processedData.push(normalized);
  }
}

return processedData.map(data => ({ json: data }));

2. Automated Incident Response

# Workflow: Incident Detection & Response
trigger: webhook
steps:
  - validate_incident:
      type: function
      code: |
        const incident = $json;
        const severity = incident.level === 'critical' ? 'P1' : 
                        incident.level === 'high' ? 'P2' : 'P3';
        return { ...incident, severity, assigned_team: 'ops' };
        
  - notify_slack:
      type: slack
      channel: '#incidents'
      message: 'Incident {{$json.severity}}: {{$json.description}}'
      
  - create_jira_ticket:
      type: jira
      project: 'OPS'
      issue_type: 'Incident'
      
  - if_critical:
      condition: '{{$json.severity}} === "P1"'
      then:
        - notify_oncall:
            type: email
            to: 'oncall@unhabitat.org'
        - escalate_to_manager:
            type: slack
            channel: '#management'

3. Cross-Platform Data Pipeline

// Multi-source data aggregation
const sources = [
  { name: 'city_api', endpoint: '/api/v1/cities' },
  { name: 'weather_data', endpoint: '/api/weather' },
  { name: 'economic_indicators', endpoint: '/api/economics' }
];

const aggregatedData = {};

for (const source of sources) {
  try {
    const response = await fetch(`${source.endpoint}`, {
      headers: { 'Authorization': `Bearer ${process.env.API_TOKEN}` }
    });
    
    const data = await response.json();
    aggregatedData[source.name] = {
      data: data,
      timestamp: new Date(),
      status: 'success'
    };
  } catch (error) {
    aggregatedData[source.name] = {
      error: error.message,
      timestamp: new Date(),
      status: 'failed'
    };
  }
}

return [{ json: aggregatedData }];

Advanced Features Implemented

1. Dynamic Workflow Routing

// Smart routing based on data characteristics
const routingLogic = (data) => {
  const { city, data_type, urgency } = data;
  
  if (urgency === 'high') {
    return 'emergency_pipeline';
  }
  
  if (data_type === 'financial') {
    return 'financial_validation_pipeline';
  }
  
  if (['nairobi', 'kampala', 'accra'].includes(city.toLowerCase())) {
    return 'africa_regional_pipeline';
  }
  
  return 'standard_pipeline';
};

const destination = routingLogic($json);
return [{ json: { ...data, pipeline: destination }}];

2. Error Handling & Recovery

error_handling:
  retry_policy:
    max_attempts: 3
    backoff_strategy: exponential
    initial_delay: 1000
    
  fallback_actions:
    - log_error:
        destination: elasticsearch
        index: n8n_errors
        
    - notify_admin:
        method: slack
        channel: '#n8n-alerts'
        
    - queue_for_manual_review:
        destination: redis_queue
        priority: high

3. Performance Monitoring

// Performance tracking node
const startTime = Date.now();
const workflowId = $workflow.id;
const executionId = $executionId;

// Process data
const result = processData($json);

const endTime = Date.now();
const duration = endTime - startTime;

// Log performance metrics
await fetch('/api/metrics', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    workflow_id: workflowId,
    execution_id: executionId,
    duration_ms: duration,
    timestamp: new Date().toISOString(),
    success: true
  })
});

return [{ json: result }];

  return availableWorkers[
    Math.floor(Math.random() * availableWorkers.length)
  ];
};
