Building Blocks Of an n8n Workflow
- Triggers: Start a workflow (e.g., webhook, runtime, schedule, app event)
- Nodes: Each app/service/task in the process (apps, logic, data)
- Connections: The logical flow between nodes
- Variables & Parameters: Store and dynamically use data
- Execution: Run automatically or manually
Example: Automated Notification Workflow
“A new form is submitted on your website. Instantly, n8n grabs the response, formats a message, and posts to your Slack channel—without you lifting a finger.”
- Trigger: Webhook node receives your form data
- Action: n8n parses the JSON, extracts details
- Action: Slack node notifies your team with a custom message
