# n8n Automation Specialist

## Core Philosophy

> "If you do it more than twice, automate it. n8n is the glue between your systems."

## n8n Architecture

```
Trigger Nodes (When something happens)
    │
    ▼
Action Nodes (Do something)
    │
    ▼
Logic Nodes (Control flow)
    │
    ▼
Data Nodes (Transform/Store)
```

## Workflow Patterns

### Pattern 1: Webhook → Transform → API
```
[Webhook Trigger] → [Code Node] → [IF Node]
├── True  → [HTTP Request] → [Slack Notify]
└── False → [Slack Notify Rejection]
```

### Pattern 2: Scheduled ETL
```
[Cron Trigger] → [HTTP Request] → [Set Node] → [Function Node] → [Split Batches] → [Postgres] → [Slack]
```

### Pattern 3: Approval Workflow
```
[Form Trigger] → [IF Needs Approval?]
├── Yes → [Create Doc] → [Email Approver] → [Wait Webhook]
│           └── [IF Approved?] → [Yes: Execute+Notify] / [No: Rejection]
└── No  → [Auto-execute] → [Notify]
```

## Best Practices

### Node Naming
```
"Trigger — Stripe Payment Success"
"Validate — Payload Check"
"Action — Create Salesforce Lead"
"Action — Send Welcome Email"
```

### Error Handling
- **Error Workflow**: Global error capture, alert to Slack/PagerDuty
- **Continue on Fail**: Non-critical nodes skip on error
- **Retry**: 3 retries with exponential backoff for API calls
- **Fallback**: Default values when data missing

### Credentials & Security
- Never hardcode secrets — use n8n credential store
- Rotate API keys quarterly
- Use OAuth where available
- Credential sharing: project-level, not instance-wide

### Performance
- Batch operations instead of 1-by-1
- Use native nodes (HTTP Request) over Function nodes
- Enable execution logging for audit
- Delete old executions (GDPR/compliance)

## Node Type Guide

| Need | Node | Why |
|------|------|-----|
| Webhook trigger | Webhook | Receive HTTP requests |
| Schedule | Cron | Time-based triggers |
| HTTP API | HTTP Request | Generic REST calls |
| Database | Postgres/MySQL/MongoDB | Direct DB ops |
| Transform | Set/Code/Split | Data manipulation |
| Condition | IF/Switch | Branching logic |
| Loop | Split In Batches | Iterate collections |
| Wait | Wait | Pause for human/async |
| Notify | Slack/Email/Discord | Alerts |
| File | Read/Write Binary | File handling |
| AI | OpenAI/Anthropic | AI-powered processing |
