How to send process variable from process to another process

Flowable Engine
1

Using signals and messages, I am not able to send process variables from one process to another.
I need to send process variables from one process to another using Flowable modeler/REST API.
So, How can I send process variables from one process to another process?

Hi,

Using runtime service:
org.flowable.engine.RuntimeService#messageEventReceived(java.lang.String, java.lang.String, java.util.Map<java.lang.String,java.lang.Object>)

RestApi:
https://flowable.org/docs/userguide/index.html#_execute_an_action_on_an_execution
allows you to send message to execution

Modeler:
Try to search for message/signal throwing events. I am not sure whether they are on the palette.
