Hand your repetitive work over to automation
Start by opening Woow n8n, using someone else's template, and building your first workflow. Then continue through expressions, the Code node, AI Agent, and Webhook. There are 22 chapters + 3 appendices, each taking 10 minutes. Find the Sales Handbook, Prompt Library, and Skill Handbook in the Resource Hub.
Getting oriented
What n8n is, and how it differs from Zapier/Make
Why the company chose n8n, how it differs from Zapier/Make, and which repetitive work it can take off your hands.
02Open Woow n8n: sign in and a 5-minute tour
Open n8n.woowtech.io, get your account, confirm that your device can connect, and learn the main parts of the interface.
03What the workspace looks like
Learn the canvas, nodes panel, Executions, Templates, and Credentials in one pass so you do not get lost.
Start from someone else's work
Start from the Templates gallery
n8n already has thousands of ready-made workflows. Copying someone else’s work is the fastest way to start.
05Find JSON on n8n.io and paste it in
n8n.io/workflows has a huge library of shared workflows. Copy and paste the JSON to make one yours.
06Change someone else's workflow: remap fields, swap the trigger, run it
Using someone else's workflow unchanged is wishful thinking. Learn how to adapt it to your needs.
Build your first one
The four node families: Trigger / Core / App / Cluster
The nodes panel has hundreds of nodes, but they fall into four families: start, act, control, and AI clusters.
08Your first workflow: push Google Calendar to Slack at 8:00 every morning
Build a useful workflow from scratch: send today’s calendar to Slack at 8:00 every morning.
09What an item is, and how data moves between nodes
Understand n8n items: how many items a node receives and what the next node gets.
10Three triggers: Manual / Schedule / Event
When does a workflow run? Choose manual, scheduled, or external-event triggers.
Everyday integrations
Popular SaaS integrations: Slack, Gmail, Google Sheets and Drive
Four services office workers connect most often: Slack notifications, Gmail messages, Google Sheets records, and Drive storage.
12The HTTP Request node: reach every API without an official integration
Use the HTTP Request node for services without a ready-made n8n node. It handles 80% of custom integrations.
13Managing credentials: keys, OAuth, and where sharing stops
A workflow needs access to your accounts to work for you. Learn how to store and share that access safely.
14Expressions: it all starts with {{ $json.field }}
Use an expression when a node field needs data from an earlier node. This chapter covers the five forms you will use most.
Flow control
IF / Switch: conditional branching
Send values over 100 down branch A and values under 100 down branch B: build conditions visually.
16Merge / Loop Over Items / Split Out / Aggregate: working with many items
Process many items, combine several paths, and split arrays—the data plumbing in n8n.
17Error handling: error workflow / retry / wait
What happens when a workflow fails overnight? Add an error workflow, retries, and waits.
Reshaping and reusing data
Going further
Code node: a few lines of JavaScript inside a workflow
When ready-made nodes cannot shape the data, the Code node is your escape hatch. Beginners can start by copying the examples.
21AI Agent: give a workflow a node that thinks
Ordinary nodes follow rules. AI Agent can make judgments for customer support and data organization.
22Webhook: let outside systems call into n8n
Forms, HA triggers, and LINE messages all enter n8n through the Webhook node.
Appendices
Settings reference
Execution retention, timezone, log level, and what Personal and Workspace settings control.
BError troubleshooting
Red nodes, timeouts, expired credentials, 429 rate limits, and missing sub-workflows—symptoms matched to fixes.
CHow it works underneath, for the curious
Community vs Cloud vs Enterprise, self-hosting choices, queue mode, and databases.
