Step 1: Install n8n

Install n8n for visual workflow automation Get n8n running on your infrastructure

Quick start with Docker:

docker run -d \
  --name n8n \
  -p 5678:5678 \
  -v n8n_data:/home/node/.n8n \
  -e GENERIC_TIMEZONE="Your/Timezone" \
  n8nio/n8n

Access at http://localhost:5678.

Production setup with persistence:

docker run -d \
  --name n8n \
  -p 5678:5678 \
  -v ~/.n8n:/home/node/.n8n \
  -e N8N_BASIC_AUTH_ACTIVE=true \
  -e N8N_BASIC_AUTH_USER=admin \
  -e N8N_BASIC_AUTH_PASSWORD=yourpassword \
  -e GENERIC_TIMEZONE="America/New_York" \
  n8nio/n8n

Set up Anthropic credentials:

1. Go to Settings → Credentials
2. Add new credential → Anthropic
3. Paste your API key

Now you can use Claude in any workflow.

Step 2: Your First AI Workflow

Build your first AI-powered automation workflow

Example: Daily email digest

1. Trigger: Schedule (daily at 8 AM)
2. Action: Gmail → Get emails from last 24 hours
3. Action: Anthropic → Summarize emails
4. Action: Slack → Post summary

Building it:

1. Create new workflow
2. Add Schedule trigger node
3. Add Gmail node → "Get Many" messages
4. Add Anthropic node → Use this prompt:

Summarize these emails concisely:

{{$json.emails.map(e => 
  `From: ${e.from}\nSubject: ${e.subject}\nBody: ${e.body}`
).join('\n\n---\n\n')}}

Format as:
**Urgent:** [list]
**Important:** [list]
**FYI:** [list]

5. Add Slack node → Send message
6. Test and activate

Your daily digest runs automatically every morning.

Step 3: Content Processing Workflows

Automate content processing with AI

Use case: Social media repurposing

Blog post → AI → Multiple social posts

Trigger: RSS (new blog post)
↓
HTTP Request: Fetch full article
↓
Anthropic: Generate social content
  - 3 tweet variations
  - 1 LinkedIn post
  - 1 email newsletter blurb
↓
Split: Separate outputs
↓
Buffer/Twitter: Schedule tweets
↓
LinkedIn: Post update
↓
Email: Save to drafts

Anthropic node prompt:

Read this blog post and create:

1. Three tweet variations (max 280 chars each)
2. One LinkedIn post (professional tone, 150-200 words)
3. One email newsletter blurb (50-100 words)

Return as JSON:
{
  "tweets": ["...", "...", "..."],
  "linkedin": "...",
  "email": "..."
}

Blog post:
`{{$json.content}}`

Step 4: Data Transformation Workflows

Transform data intelligently with AI nodes

Use case: Lead qualification

Webhook: New form submission
↓
Anthropic: Analyze and score lead
  - Company size
  - Budget indicators
  - Intent signals
  - Priority score (1-10)
↓
IF: Score > 7
  ↓ Yes: Slack alert + CRM priority
  ↓ No: Add to nurture sequence

Scoring prompt:

Analyze this lead form submission and provide:
- Estimated company size (startup/smb/enterprise)
- Budget indicators (low/medium/high)
- Intent signals (browsing/evaluating/ready)
- Priority score (1-10)
- Recommended action

Form data:
`{{JSON.stringify($json.form)}}`

Return as JSON.

Step 5: Customer Support Automation

Automate support workflows with n8n and AI

Use case: Ticket routing and drafting

Intercom: New conversation
↓
Anthropic: Analyze intent and urgency
↓
Switch: Route by category
  → Billing: Assign to billing team
  → Technical: Assign to engineering
  → Sales: Assign to sales + draft response
  → General: Draft FAQ response
↓
Intercom: Add internal note + suggested reply

Classification prompt:

Classify this support ticket:

Categories: billing, technical, sales, general
Urgency: low, medium, high, critical

Also draft a helpful response.

Ticket:
`{{$json.message}}`

Return as JSON:
{
  "category": "...",
  "urgency": "...",
  "draft_response": "..."
}

Best Practices

Build reliable, maintainable AI workflows

Error handling:

• Add Error Trigger node for failed workflows
• Use Try-Catch patterns for critical paths
• Set up Slack/email alerts for failures

Cost management:

• Use smaller models for simple tasks
• Cache responses when appropriate
• Rate limit external triggers

Testing:

• Use n8n's execution preview
• Test with sample data first
• Log AI inputs/outputs for debugging

Maintenance:

• Document workflow purposes
• Use descriptive node names
• Version control with n8n's export feature
