We cut to the chase with this kick start primer to Camunda BPM for Developers. Learn the easiest ways to get Camunda BPM up and running in no time. To round it off, we will deploy a simple process and show different ways to integrate an existing REST service into this process. The examples shown will contain suitable approaches for Java and non-Java developers.
