n8n Workflow Logic: Filter API Data with Loops & IF Conditions

Welcome to Class 2! Today, we're moving from theory to practice by building our first real data-processing workflow. We will learn how to fetch data from a public API, use a loop to process it item by item, and then save the filtered data into Google Sheets based on conditional logic (the IF node).
This class will teach you how to make automated decisions in n8n, which is an essential skill for creating more complex and powerful workflows.

✨ WHAT YOU WILL LEARN IN THIS VIDEO:
Fetching API Data: Using the HTTP Request node to get a list of users from a public API (JSONPlaceholder).
Looping Over Data: How to use the "Loop Over Items" node to go through a list of items one by one.
Conditional Logic: Using the IF node to filter data based on specific criteria (e.g., name starts with 'C').
Google Sheets Integration: Using the "Append Row" operation to automatically add processed data to a Google Sheet.
App Event Triggers: How to trigger another workflow when a new row is added to a Google Sheet.
Bonus Data Transformation: A brief overview of other useful nodes like Filter and Limit.
