Think about the repetitive tasks you do every day. Maybe you get an email with an attachment, download it, rename it, and upload it to a cloud storage folder. Or perhaps you copy information from a customer form into a spreadsheet and then send a confirmation message.

Each of these processes is a workflow. n8n is a tool that automates these workflows for you. It acts like a digital assistant that connects different applications and services, allowing them to talk to each other and pass data along without any manual effort on your part.

Automation in n8n is built around two fundamental concepts: workflows and nodes. A workflow is the entire automated process from start to finish. It’s the complete map of your task.

The building blocks of a workflow are called nodes. Each node represents a single step or action in your process. You create a workflow by connecting these nodes together in the sequence you want them to run.

Every workflow starts with a trigger node. This is the event that kicks off your automation. A trigger could be a specific time (like every Monday at 9 AM), a new message in a chat app, or a new row added to a database. The trigger node listens for this event and, when it happens, starts the workflow and passes its data to the next node.

Following the trigger are one or more action nodes. These are the workhorses of your workflow. An action node takes the data it receives from the previous node and performs a task with it. This could be anything from sending an email, creating a calendar event, or updating a customer record in a CRM.

Data flows from one node to the next, allowing you to chain together complex operations. The output of one node becomes the input for the next, creating a seamless and powerful automated process.

Now, let's test your understanding of these core concepts.

With this foundation, you're ready to start thinking about the kinds of tasks you can automate.
