n8n-workflows

Overview

n8n is a fair-code licensed workflow automation tool. It provides 400+ integrations, visual workflow design, self-hosting options, and code flexibility with JavaScript/Python nodes.

Capabilities

• Build workflows with 400+ pre-built nodes
• Use triggers: webhook, cron, email, file changes, database
• Write custom code in JavaScript/Python nodes
• Handle errors with error workflows
• Use expressions for dynamic data mapping
• Self-host or use n8n cloud
• Manage credentials securely

When to Use

Trigger phrases:

• "n8n workflows"

• "Automating business processes across multiple SaaS tools"

• "Building API integrations without coding"

• "Needing self-hosted automation (data sovereignty)"

• Automating business processes across multiple SaaS tools

• Building API integrations without coding

• Needing self-hosted automation (data sovereignty)

• Complex workflows with branching, loops, error handling

• Replacing Zapier/Make with more flexibility

When NOT to Use

• Task is simple enough for Zapier (use Zapier for no-code)
• You need complex code execution (use Pipedream)
• Task is about data storage, not workflow automation
• You don't have n8n instance running
• Task requires real-time processing (use streaming tools)
• You need to build a custom application (use development tools)

Workflow Structure

Trigger → Set Variables → HTTP Request → IF Condition → Send Email / Slack
                                            ↓
                                      Code Node → Database

Expressions

// Access previous node data
{{ $json.fieldName }}
{{ $json.data.items[0].name }}

// Access trigger data
{{ $json.body.query }}

// Transform data
{{ $json.name.toUpperCase() }}
{{ $json.items.filter(i => i.active) }}

// Date
{{ $now.format('yyyy-MM-dd') }}
{{ $now.minus({ days: 7 }).toISO() }}

// Environment variables
{{ $env.API_KEY }}
