🔄 Over 350 Pre-built Integrations

What it means:
n8n supports ready-made “nodes” (connectors) for over 350 apps and services like:

Google Sheets (create/update/read rows)
Slack (send messages, alerts)
Airtable (manage databases)
Discord, Gmail, Twitter, Trello, Stripe, Notion, and more

How it works:
When creating a workflow, you can add a node like “Google Sheets” ➜ choose the action (e.g., add row) ➜ connect your account ➜ map the data from previous steps.

Example:
When a form is submitted on your website ➜ send data to Google Sheets ➜ notify you in Slack.

🧠 Conditional Logic (If/Else Rules)

What it means:
You can add logic into your automation — like making decisions based on values.

How it works:
n8n has a node called "IF", where you set conditions. For example:

If payment status = "Success" ➜ send confirmation email
Else ➜ send failure notification

Example:

Customer pays via Stripe ➜ Check if payment succeeded ➜ Yes: give access | No: alert admin.

Self-hosting Option

What it means:
You can install n8n on your own VPS, local server, or cloud (like Elest.io) instead of relying on third-party platforms.

How it works:
Use Docker, Node.js, or click-to-deploy options on platforms like:

Elest.io
Render.com
DigitalOcean, AWS, etc.

Benefit:
You control your data, have no monthly fees, and can scale freely.

Drag-and-Drop Interface

What it means:
n8n has a visual workflow builder, where you drag boxes (nodes) and connect them to build your automation — no programming needed.

How it works:

Start with a trigger node (e.g., "New form entry")
Add an action node (e.g., "Send email", "Add to Google Sheets")
Link nodes together like a flowchart

Good For:
Marketers, business owners, and non-developers who want visual automation.

Custom Functionality (JavaScript Code)

What it means:
You can write small JavaScript functions in the "Function" node to manipulate data or add logic that default nodes can't do.

How it works:
Use the Function or FunctionItem node to write custom logic like:

js
return {
  json: {
    fullName: $json.firstName + " " + $json.lastName
  }
};

Use Case:
Merge names, calculate dates, or validate fields before sending data to the next step.

Webhooks and API Support

What it means:
n8n can send or receive data from any service that supports HTTP API or webhooks — even if it's not in the 350+ pre-built list.

How it works:

Use Webhook node to trigger workflows when external systems send data.
Use HTTP Request node to call external APIs and fetch/post data.

Example:
When someone makes a purchase ➜ Your payment gateway sends a webhook ➜ n8n receives it ➜ triggers workflow (e.g., send invoice + notify team).
