NewSubworkflow
Start
Where a subworkflow begins, with the inputs a project gives it when it runs it.
Start is where a subworkflow begins. Its inputs are what a project gives the subworkflow in its Subworkflow step. A subworkflow has exactly one Start step, and a new subworkflow already has it.


Settings
Inputs
Steps in the subworkflow read an input with its prefix, as {{state.kyc_nationalId}}. Select Add input for each one, up to 20.
Prop
Type
With no inputs, a project runs the subworkflow without giving it anything.
Variable prefix
The prefix every variable in this subworkflow starts with, such as kyc_. You can change it in Settings until you publish version 1. After that it's fixed, so projects using it keep working.
Outputs
Start has one output, to the subworkflow's first step.
