Understanding n8n Concepts

Nodes

Nodes are the building blocks of your workflows. Each node performs a specific action or connects to a specific service.

Connections

Connections link nodes together and define how data flows between them.

Expressions

Use expressions to dynamically reference data:

• {{ $json.fieldName }} - Access JSON data
• {{ $now }} - Current timestamp
• {{ $runIndex }} - Current run number

Common Workflow Patterns

1. Data Synchronization

Sync data between different systems like CRM and email marketing tools.

2. Automated Reports

Generate and send daily/weekly reports automatically.

3. Social Media Management

Schedule posts and track engagement across platforms.

4. Customer Support

Automatically create support tickets and send acknowledgments.

Best Practices

1. Start Simple

Begin with basic workflows and gradually add complexity.

2. Use Error Handling

Always include error handling nodes to manage failures gracefully.

3. Document Your Workflows

Add notes and descriptions to help others understand your logic.

Regularly check workflow execution times and success rates.
