Understanding Nodes, Workflows, and Data Flow

Workflows are the backbone of n8n. They represent a series of tasks that the automation engine performs one after the other. Each task is a node, and nodes are connected in a way that data flows smoothly.

Nodes: The Building Blocks

Nodes in n8n come in different types:

• Trigger Nodes:
  Examples include:

  • Manual Trigger: Start the workflow manually.
  • Cron Trigger: Execute tasks at predefined intervals.
  • Webhook Trigger: Activate workflows through HTTP requests.

• Action Nodes:
  Carry out specific actions such as:

  • Sending emails using Gmail.
  • Updating a record in a database.
  • Posting messages on social media.

• Core Nodes:
  Handle data processing and logical branching:

  • If Node: Implements true/false conditions.
  • Switch Node: Routes data through multiple branches based on conditions.
  • Merge Node: Combines data from different branches.

• Custom Code Nodes:
  For situations where you need to write custom scripts, allowing you to extend n8n’s functionality using JavaScript or Python.

Data Flow in n8n

Data passed between nodes is commonly formatted in JSON. This helps ensure consistency regardless of the data source. When working with data, you can view it in three main formats:

• Table View: A neat, tabular display that’s easy to read.
• Raw JSON: Useful for troubleshooting and debugging.
• Schema View: Offers a visual representation of the data structure.

Consider a simple example: if you use a node to fetch data from an API, the output might look like this:

This tabular view can help you understand what data is available for further processing. As you connect nodes, the flow of data from one step to the next should be seamless, allowing you to build complex workflows without getting lost in the details.

Integrating AI into Your Workflows

As automation evolves, integrating AI has become essential for creating smarter, more responsive workflows. n8n’s native AI support opens new doors for both simple and complex use cases.

Why AI in Workflow Automation?
