Connecting Unity Games to n8n Workflows: Announcing the Workflow Bridge Asset

Built with n8n

Hi n8n Community!

My name is Oriol Sala Sobrino, I’m a Unity developer and a big admirer of the n8n platform. Following a suggestion from the n8n team via direct message, I’m excited to share a project I’ve been working on that I believe will be highly valuable for game developers using n8n.

Key Features (Why it’s different):

  • Persistent Offline Queue: Requests are automatically queued when the player is offline and sent reliably (based on priority!) when the connection restores. No more lost data!

  • Intelligent Retry System: Handles temporary network issues or server hiccups gracefully using exponential backoff with jitter.

  • Built-in Security: Includes AES-256 encryption for sensitive data (like API keys) and HMAC-SHA256 request signing for verifying data integrity and authenticity directly within your n8n workflows. Also features automatic log obfuscation.

  • Network Adaptation: Automatically detects network type (WiFi/Cellular), measures latency, and even monitors battery status on mobile, allowing developers to adapt behaviour (e.g., enable compression automatically on cellular).

  • Effortless Data Handling: Automatically maps common Unity types (Vector3, Quaternion, Color, GameObject, Transform, etc.) to n8n-friendly JSON or FormData. Easily extensible for custom data types.

  • n8n Specifics: Supports executing webhooks and running full workflows with type-safe responses, including automatic polling for n8n Wait nodes.

  • Zero Scene Setup: Uses a unique Singleton ScriptableObject pattern (AutomationManager) for easy configuration and automatic persistence across scene loads – no prefabs needed.

  • Multi-Environment Config: Easily switch between Development, Staging, and Production n8n instances via the AutomationConfig asset.

Why I’m Sharing This Here:

I believe Workflow Bridge can significantly simplify how Unity developers leverage the power of n8n for backend logic, analytics, AI integration (examples included!), live ops, and much more, while ensuring reliability and security.

Next Steps:

The asset is almost ready for launch on the Unity Asset Store. I wanted to share it with the n8n community first.

  • I’d love to hear your thoughts or answer any questions you might have!

  • As mentioned in my DM, I’m happy to share the detailed architecture diagram if there’s interest.

  • I’ll post an update here once it’s officially launched on the Asset Store.

Thank you for creating such an amazing platform like n8n, and thanks to the team for suggesting I post here!

Best regards, Oriol Sala Sobrino
