Sub-flows are one of the most powerful features in Oppz AI. They let you use an existing flow as a node inside another flow, enabling reusable, modular, and scalable automation.

Sub-flows can be found in the nodes library:

🎯 Why Use Sub-Flows?

✅ Cleanliness & Modularity

Breaking complex processes into smaller sub-flows keeps things:

• Easier to understand
• Easier to maintain
• Easier to debug

💡 Tip: Think of each sub-flow as a “mini-flow” — small, focused, and reusable across different workflows.

📚 Multi-Layer Nesting

Sub-flows can also be nested. This means one flow can call another, which in turn can call yet another.

Example: Processing eCommerce orders from an email inbox →

1. Inbox Flow → Extract orders
2. Order Flow → Process a single order
3. Item Flow → Process each item in that order

👉 This structure keeps things clear and lets you work step by step without overwhelming complexity.
