POST method for process definition BPMN model

Flowable Engine
1

Is there a way to edit process definition BPMN model?

  1. I would like to replicate an app multiple times but formKey inside tasks will vary inside process definition BPMN model in each APP.
  2. There is a GET method to obtain a process definition BPMN model which will list out all the all elements inside process workflow. I would like to alter the formKey in this response JSON and modify the BPMN model.
  3. What are the models listed in this Request URL, I’m unable to see any models inside the response.
