• "set up a workflow that..."
• "automate my [process]"
• "n8n workflow for..."

Procedures#

1. Understand the Request#

• Define data flow between nodes
• Add error handling and conditional logic
• Include logging for debugging

3. Generate the JSON#

• Output complete, valid N8N workflow JSON

Example Workflows#

Example 1: Lead Capture to CRM#

User Request: "Create a workflow that captures leads from a web form and adds them to Google Sheets"

User Request: "Create a workflow that posts to Twitter and LinkedIn when I publish a new blog post"

Generated Workflow:

json

{
  "name": "Blog to Social Auto-Poster",
  "nodes": [
    {
      "name": "RSS Read (Blog Feed)",
      "type": "n8n-nodes-base.rssRead",
      "parameters": {
        "url": "{{ secrets.BLOG_RSS_URL }}"
      },

      },
      "position": [450, 300]

      "parameters": {
        "operation": "post",
        "text": "={{ $json.linkedin }}"
      },
      "position": [650, 400]
    }
  ]
}

Error Handling#

Include proper error handling in all workflows:

• Try/Catch blocks for API calls
• Retry logic (3 attempts with exponential backoff)
• Error notifications via email or Slack
• Logging for debugging

Secrets and Credentials#

Remind users to configure these in N8N:

• API keys (Google, Slack, CRM, etc.)
• Database connections
• Webhook authentication tokens
• OAuth credentials

Testing Recommendations#

1. Test with test data first
2. Enable "Dry Run" mode where available
3. Check node output at each step
4. Verify credentials are properly configured
5. Test error scenarios (invalid data, API failures)

Output Format#

Always output:

1. Workflow Name - Clear, descriptive title
2. Description - What the workflow does
3. Prerequisites - Required accounts and credentials
4. JSON Code Block - Complete, import-ready workflow
5. Setup Instructions - Step-by-step guide
6. Testing Steps - How to verify it works
