Decision API flows
With the decision steps, the modeler can decide which branch (steps) must
be taken depending on values of input API Flow parameters.
You can add or remove branches by right-clicking the diamond shape. There is always one default branch. It is the one at the bottom and marked in the model with the small line across the input line. Default branch cannot be removed.
The flow only executes the first, from top, matching branch to avoid conflicts and results being merged.
API Flow parameters that are created in the steps inside a decision flow cannot be referenced directly. You must use a decision step name as an identifier instead of an individual step name.
