Hi,

I’m trying to add some process specific properties and read them using the REST API provided by Camunda. Here is how it looks like in Modeler.

The problem is I couldn’t find any way to read these values via REST (the only way I was able to get these values was by using the GET /process-definition/{id}/xml service - Camunda BPM documentation | docs.camunda.org but process definition data is related to the whole process, what I need is different data for different process instances).

  1. Is there any way to get these values through a web service call?
  2. If not, is there another way to set some process instance specific properties and be able to access them regardless of the current task?

Thank you!
