Managing Variables

Variables are used in dialog flows to store data generated during flow execution. Variables defined in a flow can be used only in this flow. If a variable is involved in multiple flows, you need to define the variable as a global variable. Global variables can be referenced by all flows. Global variables are used in flows. The format of a global variable is ${GLOBAL.ParamName}.
