Building Your First Workflow: A Practical Example

Let's create a practical workflow that monitors GitHub issues and automatically creates Slack notifications with AI-generated summaries.

Step 1: Set Up the GitHub Trigger

1. Create a new workflow in n8n
2. Add a "GitHub Trigger" node
3. Configure it to monitor "Issues" events
4. Set up your GitHub webhook URL

Step 2: Add AI Processing

1. Add an "OpenAI" node after the GitHub trigger
2. Configure it to summarize the issue content
3. Use a prompt like: "Summarize this GitHub issue in 2-3 sentences, highlighting the key problem and impact"

Step 3: Send Slack Notification

1. Add a "Slack" node
2. Configure your Slack workspace and channel
3. Create a message template using the AI summary

Example Workflow Configuration

{
  "nodes": [
    {
      "name": "GitHub Issues",
      "type": "n8n-nodes-base.githubTrigger",
      "parameters": {
        "events": ["issues"],
        "repository": "your-org/your-repo"
      }
    },
    {
      "name": "AI Summary",
      "type": "n8n-nodes-base.openAi",
      "parameters": {
        "operation": "chat",
        "prompt": "Summarize this GitHub issue: {{ $json.issue.title }} - {{ $json.issue.body }}"
      }
    },
    {
      "name": "Slack Notification",
      "type": "n8n-nodes-base.slack",
      "parameters": {
        "channel": "#development",
        "text": "🚨 New GitHub Issue: {{ $node['GitHub Issues'].json.issue.title }}\n\n📝 AI Summary: {{ $node['AI Summary'].json.choices[0].message.content }}"
      }
    }
  ]
}

Advanced Features and Use Cases

1. Custom Code Execution

n8n allows you to write custom JavaScript/TypeScript code for complex data transformations:

// Example: Custom data processing in a Code node
const processedData = items.map(item => {
  const data = item.json;
  
  // Custom business logic
  const priority = calculatePriority(data.urgency, data.impact);
  const assignee = determineAssignee(data.category);
  
  return {
    ...data,
    priority,
    assignee,
    processedAt: new Date().toISOString()
  };
});

return processedData;

2. Error Handling and Retry Logic

Implement robust error handling with built-in retry mechanisms:

{
  "retryOnFail": true,
  "maxTries": 3,
  "waitBetweenTries": 1000,
  "onError": "continueErrorOutput"
}

3. Conditional Logic and Branching

Use IF nodes to create conditional workflows:

// Example condition
{{ $json.priority === 'high' && $json.customer_tier === 'enterprise' }}
