Understanding n8n Nodes: The Building Blocks of Automation

In n8n, every action, every integration, and every piece of logic is encapsulated within a “node.” Nodes are like Lego bricks, each with a specific function, that you connect to build your workflow.

We’ll categorize these essential nodes to help you understand their purpose and when to use them.

Category 1: Triggers – Kicking Off Your Workflows 🚦

These nodes are the starting point of your workflows. They listen for specific events or occur at predefined times.

1. Webhook Trigger: 🌐

   • What it does: Starts a workflow when a specific URL (webhook) receives data (e.g., a form submission, an event from another service).
   • Example: Trigger a workflow whenever a new customer signs up on your website via a form submission.

2. Cron Trigger: ⏰

   • What it does: Runs a workflow at scheduled intervals (e.g., every day at 9 AM, every Monday).
   • Example: Send out a daily sales report email every morning.

3. Manual Trigger: 👆

   • What it does: Allows you to manually execute a workflow with a single click. Great for testing or one-off tasks.
   • Example: Manually trigger a data cleanup script before a big migration.

4. Form Trigger: 📝

   • What it does: Generates a simple web form that, when submitted, triggers your workflow.
   • Example: Create a quick internal request form for employees to submit IT tickets.

5. Poll Trigger (e.g., RSS Feed, Email): 🔄

   • What it does: Periodically checks a source (like an RSS feed or email inbox) for new items and triggers the workflow if found.
   • Example: Monitor a blog’s RSS feed for new posts and automatically share them on social media.

Category 2: Core Logic & Data Manipulation – The Brains of Your Workflow 🧠

These nodes are fundamental for controlling flow, transforming data, and making decisions.

6. Set: 🛠️

   • What it does: Adds, updates, or removes fields from your data items. Essential for preparing data.
   • Example: Add a status: "processed" field to each item after it’s been handled.

7. HTTP Request: 🔗

   • What it does: Makes HTTP calls (GET, POST, PUT, DELETE, etc.) to any API. This is your universal connector!
   • Example: Fetch data from an external API, post data to a custom webhook, or interact with services n8n doesn’t have a dedicated node for.

8. IF: 🤔

   • What it does: Allows your workflow to follow different paths based on a condition (e.g., if a value is greater than X, if a string contains Y).
   • Example: If an order total is over $1000, send an alert to the sales manager; otherwise, just process the order normally.

9. Split In Batches: 📦

   • What it does: Divides a large list of items into smaller batches, processing each batch sequentially. Useful for APIs with rate limits.
   • Example: Process 10,000 customer records by sending them to an API in batches of 100.

10. Merge: 🤝

    • What it does: Combines data from different branches or steps in your workflow.
    • Example: After processing items separately (e.g., one branch for successful, one for failed), merge them back together to generate a single report.

11. Code: 💻

    • What it does: Executes custom JavaScript code to perform complex data transformations, calculations, or logic.
    • Example: Write a custom function to calculate a discount based on multiple criteria or to parse highly specific data.

12. Function Item: ⚡

    • Example: For each customer record, format their address into a single string.

13. Move Binary Data: 📁

    • What it does: Manages binary data (files) within your workflow, allowing you to move, rename, or delete them.
    • Example: Move a downloaded image from a temporary folder to a permanent storage location.

14. Edit Fields: ✏️

    • What it does: Provides a more visual way to rename, remove, or reorder fields compared to the Set node.
    • Example: Rename cust_name to customerName for consistency.

15. Convert: 🔄

    • What it does: Converts data between various formats (e.g., CSV to JSON, JSON to XML, Base64 encoding/decoding).
