There are two kinds of people — those who automate, and those who dig.

Start with the trigger node. Every workflow begins with a trigger — a schedule, a webhook, an incoming email. Then chain: trigger, fetch data, transform data, output. Every automation follows this pattern.

Schedule trigger. 7am daily. Gmail node reads unread. Google Sheets node writes. Three nodes. Test it.

Three nodes! I connected them but Gmail wants OAuth credentials. Why does everything have to be so painful! It's like they don't WANT you to use their own products!

OAuth is a security protocol. Create a Google Cloud project, enable Gmail API, generate credentials, paste into n8n. Ten minutes. One-time cost — every Google automation reuses the same credentials.

n8n docs have a step-by-step for Google OAuth. Follow it exactly.

Got it working! My workflow runs! Six emails processed automatically. I feel like a GENIUS! But I need to extract specific data from email bodies — invoice numbers, amounts.
