Example Workflows

Example 1: Lead Capture to CRM

      },
      "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
