01 · The anatomy of a flow

Elements, resources, connectors — and the two panels in Flow Builder everyone ignores until a debug session forces them to look.

Resources are variables wearing a costume

Every formula, variable, and record collection is a resource. Name them like code — get_Account, var_SendEmail — and your future debug logs become readable.

The debug panel tells the truth

Debug runs show every element's inputs and outputs. Learn to read one now; every later lesson assumes you can.
