If you're new to GCP Pub/Sub or new to n8n or both, this primer gets you comfortable in an afternoon. No jargon. No fluff.
What GCP Pub/Sub is
GCP Pub/Sub is a queue tool. It stores records and events, and exposes an API. n8n talks to that API on your behalf.
What n8n is
n8n is a workflow platform. You wire nodes together to move data and trigger actions across GCP Pub/Sub and everything else you use.
Your first workflow
Trigger on a GCP Pub/Sub event → transform → write somewhere. That's automation. Really. That's it.
Where to go next
Add a second workflow. Then a third. Automation compounds — three small workflows beat one big one every time.
