I want to start my process instance by message event in JBPM Workbench/Kie-Server (7.7.0) but I can't find the request for it.
I found a way to achieve this by the POST request with empty body:
/server/containers/{id}/processes/instances/signal/{sName}
Instead of signal name I have to send message event id. But there is a problem with it - id is changed by JBPM Web Designer at any time when I edit the event.
Is it possible to start process instance by message? I didn't find this in the DOCS.
My process (Evaluation sample with added start message event)
