[goevexx]

Summary

Add comprehensive example workflow collection for the Pterodactyl n8n node, completing Tier 2 of the roadmap. This PR delivers 6 production-ready workflow templates with complete documentation.

Workflows Added

🔄 01 - Automated Server Backup

Daily scheduled workflow that backs up all servers with completion verification

• Demonstrates: Loops, scheduling, batch processing, error handling

📊 02 - Server Resource Monitoring

Monitor CPU/memory usage every 5 minutes and alert on threshold breaches

• Demonstrates: Conditional logic, thresholds, expressions, alerting

🚀 03 - File Deployment Pipeline

CI/CD integration for automated file deployment from Git webhooks

• Demonstrates: Webhook triggers, Git integration, rollback safety

🗄️ 04 - Database Provisioning

Automated database creation with credential management and validation

• Demonstrates: Validation, conditional creation, secure credentials

👤 05 - User Onboarding

Multi-step customer onboarding with setup files and email notifications

Pull Request Review: Example Workflows Addition

Excellent work on completing Tier 2 of the roadmap! This PR adds substantial value with 6 production-ready n8n workflow templates and comprehensive documentation.

Strengths

• Outstanding README structure with thorough setup instructions
• Beginner-friendly with clear prerequisites and difficulty ratings
• Template guide is an excellent resource for contributors
• Diverse, realistic use cases
• Proper n8n structure and consistent naming
• No hardcoded credentials

Critical Issues to Fix

1. JSON Expression Syntax Errors

Several workflow JSON files use incorrect expression syntax. Lines 130, 147 in 01-automated-server-backup and similar in other workflows use {{ }} instead of n8n's ={{ }} format. This will prevent expressions from evaluating correctly.

2. API Response Field References

Line 63 in 01-automated-server-backup: serverId references $json.identifier but Pterodactyl Client API returns $json.attributes.identifier. Same issue on line 93 with backupId. Need to add .attributes to field paths.

3. Missing Error Handling

No continueOnFail or retry settings configured. Single API failure will stop entire workflow. Recommend adding error handling to critical nodes.

4. Security Considerations

Add explicit warning about not committing real webhook URLs. Consider using n8n credentials for webhook URLs instead of hardcoding.

Recommendations

Testing Required

1. Import each workflow into test n8n instance
2. Verify all nodes render correctly
3. Test execution with test Pterodactyl panel
4. Validate all JSON files

Documentation Improvements

• Add execution time estimates
• Document tested versions more specifically
• Add notes about execution timeout limits for large deployments
• Consider cost considerations for cloud n8n users

Future Enhancements

• Add JSON schema validation in CI
• Add automated workflow import tests
• Standardize node positioning across workflows

Conclusion

High-quality contribution that advances project goals significantly. The identified issues are straightforward to fix. Once critical syntax errors are corrected and workflows validated through manual testing, this will be ready to merge.

Recommendation: Request changes for critical fixes, then approve once addressed.

Great work! 🎉
