Iteraction between two different processes

how can two different processes iteract?
I need to send data from one process so that based on the condition another process gets started.

Hi,
use signals
https://flowable.org/docs/userguide/index.html#bpmnSignalEventDefinition
or messages
https://flowable.org/docs/userguide/index.html#bpmnMessageEventDefinition

Martin

I need to pass process variables from one process to another?
Can we do it using flowable modeler or REST?
