Page History

The Send Signal Action creates a signal instance from its inputs and transmits it to the target object, where it can cause the start of a State Machine transition or the execution of an Activity. The argument values are available to the execution of associated Behaviors. The requester continues the execution immediately. Any reply Message is ignored and is not transmitted to the requester. If the input is already a Signal instance, use the Send Signal Action.
