n8n

n8n (pronounced “n-eight-n”) is an open‑source workflow automation, Agentic AI, and orchestration platform. It lets you build AI Agents and connect APIs, databases, and services with a visual, node‑based editor, while still giving you the power to drop into code when you need it. For agentic AI, that combination—no‑code orchestration with just‑enough code—makes n8n an ideal control plane for prototyping and building systems that can perceive, plan, and act across tools.

What is the Automation

A builtin set of actions that transfer data from one point to another .

Core Concepts of automation :

• trigger It starts the automation
• Filter It is used to filter the actions
• Actions(App)It allows us to interact with app .i.e Google Sheet

Types of Triggers

• manual
• Scheduled
• According to the Application

Automation Best Practises

• Mapping

Mapping

Mapping includes the followin things are as follows:

• Understanding the Task
• Understand the use case of Tool .
• Feasibility of Automation .
• Estimation of Workload .
• need for human interaction .

WebHooks

Webhook is used to get data from another application when the particular event occurs .

nodes

Everything on the canvas is called node .

Three catagories of node :-

• Start Node (trigger)
• Action Node (.i.e. Data Transformation )
• Exit Node
