No-code AutomationStart here
- What is a workflow? Nodes joined together, started by a trigger.
- How data moves: a list of items, each with its data under
json. - Expressions, code or visual nodes: use the smallest tool that works.
- Webhooks and schedules: the two common ways a workflow starts.
- Errors and credentials: read before you publish.
The item-shape checker
n8n passes data between nodes as an array of objects, each wrapping its data under the key json. Paste JSON above to see whether it has that shape, and wrap it if it does not. It checks the shape described in the documentation; it does not run n8n and sends nothing anywhere.
Is this a course on a particular product?
It uses n8n's documentation as its source, because that documentation is open and specific. The ideas (triggers, actions, items, error handling) carry over to other tools.
Do you compare prices of automation tools?
No. Prices change often and we have not read pricing pages for this section.

This is an independent guide. It is not connected with n8n. Products change quickly: statements were read on 14 November 2026 from the n8n documentation pages named under Sources, and limits, defaults and version numbers may have changed since. We do not give prices or compare products.
