n8n Workflow Integration

n8n is the workflow automation backbone of AltSportsLeagues.ai, providing intelligent orchestration between AI services, databases, external APIs, and user interfaces. This comprehensive workflow system enables complex business processes to be automated with minimal technical overhead.

Architecture Overview

Workflow Categories

Atomic Workflows

Single-purpose workflows that perform one operation exceptionally well.

Benefits:

• Testability: Easy to unit test and validate
• Reusability: Can be composed into complex workflows
• Maintainability: Clear responsibility boundaries
• Performance: Optimized for specific operations

Examples:

• email-classification.json - Classifies incoming emails
• partnership-scoring.json - Scores partnership opportunities
• document-extraction.json - Extracts data from PDFs
• contract-generation.json - Creates contract templates

Composite Workflows

Orchestrates multiple atomic workflows to accomplish complex business processes.

Benefits:

• Modularity: Leverages existing atomic workflows
• Flexibility: Easy to modify without breaking components
• Error Handling: Granular error handling at each step
• Monitoring: Clear visibility into process progress

Examples:

• email-to-contract-pipeline.json - Full partnership acquisition pipeline
• league-onboarding-workflow.json - Complete league onboarding process
• monthly-reporting-pipeline.json - Automated business intelligence reports

Integration Workflows

Manages connections to external systems and data synchronization.

Benefits:

• Centralization: Single point of integration management
• Consistency: Standardized error handling and logging
• Maintainability: Easy updates when APIs change
• Monitoring: Clear visibility into system health

Examples:

• jira-sync.json - Synchronizes partnership data to Jira

Technical Architecture

Workflow Design Patterns

Error Handling Pattern

// n8n error handling with retry logic
{
  "nodes": [
    {
      "parameters": {
        "url": "https://api.example.com/process",
        "method": "POST",
        "options": {
          "retry": {
            "maxRetries": 3,
            "retryInterval": 1000,
            "exponentialBackoff": true
          }
        }
      },
      "continueOnFail": true,
      "onError": "continue"
    }
  ]
}

Circuit Breaker Pattern

// Circuit breaker for external API calls
{
  "parameters": {
    "code": `
      const circuitBreaker = context.getGlobalState('circuit_breaker') || {
        failures: 0,
        lastFailure: null,
        state: 'closed'
      };
 
      if (circuitBreaker.state === 'open') {
        if (Date.now() - circuitBreaker.lastFailure > 60000) {
          circuitBreaker.state = 'half-open';
        } else {
          throw new Error('Circuit breaker is open');
        }
      }
 
      try {
        // API call logic
        circuitBreaker.failures = 0;
        circuitBreaker.state = 'closed';
      } catch (error) {
        circuitBreaker.failures++;
        circuitBreaker.lastFailure = Date.now();
        if (circuitBreaker.failures >= 3) {
          circuitBreaker.state = 'open';
        }
        throw error;
      }
 
      context.setGlobalState('circuit_breaker', circuitBreaker);
    `
  }
}

Data Flow Architecture

Schema-Based Processing

All workflows use standardized data schemas for consistency:

// Schema validation in n8n
{
  "parameters": {
    "code": `
      const { validateLeagueQuestionnaire } = require('./data_layer/shared');
 
      const inputData = $json;
      const validation = validateLeagueQuestionnaire(inputData);
 
      if (!validation.valid) {
        throw new Error(\`Validation failed: \${validation.errors.join(', ')}\`);
      }
 
      return validation.data;
    `
  }
}

Idempotency Handling

Ensures workflows can be safely retried:

// Idempotency key generation
{
  "parameters": {
    "code": `
      const generateIdempotencyKey = (data) => {
        const crypto = require('crypto');
        const hash = crypto.createHash('sha256');
        hash.update(JSON.stringify(data));
        return hash.digest('hex');
      };
 
      const key = generateIdempotencyKey($json);
      const existingResult = await checkIdempotencyStore(key);
 
      if (existingResult) {
        return existingResult;
      }
 
      // Process the request
      const result = await processRequest($json);
 
      // Store result for idempotency
      await storeIdempotencyResult(key, result);
 
      return result;
    `
  }
}
