subtopic

Triggers, nodes, items and expressions

15 min applied15 min research2 curated resources

Learn how data flows: each node receives a list of items (JSON objects) and passes items to the next. Triggers start the workflow (Manual, Schedule, Webhook, Form, app triggers like Gmail). Use expressions to use data from earlier nodes, the Edit Fields (Set) node to shape data, and pin test data so you don't re-trigger every time.

Builds on: B08 · Build: Live Currency Converter (APIs, JSON, generators)
