Flow Variable (FLOW)

A cache variable that you add to a flow is called a flow variable. The variable can be used in the subsequent nodes of the flow.

Flow variables are represented by FLOW.Flow variable name. In the TTS template or SMS template, you need to use ${FLOW.Flow variable name} to specify parameters.

For example, you can define the following variables in a flow.

You can assign values to flow variables in the Semantic recognition diagram element.
