Multi-Source Feedback Processing with OpenAI & Slack Notifications

Stop duplicating your work! This template demonstrates a powerful design pattern to handle multiple triggers (e.g., Form, Webhook, Sub-workflow) within a single, unified workflow.

By using a "normalize and consolidate" technique, your core logic becomes independent of the trigger that started it, making your automations cleaner, more scalable, and far easier to maintain.

Who is this for?

• n8n developers & architects: Build robust, enterprise-grade workflows that are easy to maintain.
• Automation specialists: Integrate the same core process with multiple external systems without repeating yourself.
• Anyone who values clean design: Apply the DRY (Don't Repeat Yourself) principle to your automations.

What problem does this solve?

• Reduces duplication: Avoids creating near-identical workflows for each trigger source.
• Simplifies maintenance: Update your core logic in one place, not across multiple workflows.
• Improves scalability: Easily add new triggers without altering the core processing logic.
• Enhances readability: A clear separation of data intake from core logic makes workflows easier to understand.

How it works (The "Normalize & Consolidate" Pattern)

1. Trigger: The workflow starts from one of several possible entry points, each with a unique data structure.
2. Normalize: Each trigger path immediately flows into a dedicated Set node. This node acts as an adapter, reformatting the unique data into a standardized schema with consistent key names (e.g., mapping body.feedback to feedback).
3. Consolidate: All "normalize" nodes connect to a single Set node. This node uses the generic {{ $json.key_name }} expression to accept the standardized data from any branch. From here, the workflow is a single, unified path.

Setup

This template is a blueprint. To adapt it:

1. Replace the triggers with your own.
2. Normalize your data: After each trigger, use a Set node to map its unique output to your common schema.
3. Connect to the consolidator: Link all your "normalize" nodes to the Consolidate trigger data node.
4. Build your core logic after the consolidation point, referencing the unified data.

Taking it further

• Merge any branches: Use this pattern to merge any parallel branches in a workflow, not just triggers.
• Create robust error handling: Unify "success" and "error" paths before a final notification step to report on the outcome.
