Step
A Step is the runtime processing of a Widget, starting when that Widget is entered. Variables get set at the end of a Step.
If you're prompting a user for a text input, when they receive the inbound SMS prompt, they are actively in a Step until they exit the Widget (send a response or timeout). If the prompt is intended to set a variable, this happens at the end.

The event that caused the Flow to transition to the Step.
The current state of the Flow's Execution. As a flow executes, we save its state in this context. We save data that your widgets can access as variables in configuration fields or in text areas as variable substitution.
transitioned_fromstringOptional The Widget that preceded the Widget for the Step.
transitioned_tostringOptional The Widget that will follow the Widget for the Step.
