问题
We're trying to do a POC showing we can call an external REST service using JBPM in business-central.
We've created a new BPM, then added a REST service task. We notice at this point that a WID file is created that has REST definition. Inside the WID file, it defines things like URL, Method, and authentication.
We've sifted through all the 7.2 docs, but for the life of us, we cannot figure out how to actually set those parameters and do something useful. Does anyone have a simple "Hello World" using business central 7.2 calling out to an external process?
We see there's a predefinied REST handler: https://github.com/kiegroup/jbpm/blob/master/jbpm-workitems/jbpm-workitems-rest/src/main/java/org/jbpm/process/workitem/rest/RESTWorkItemHandler.java
We're lacking how to assemble all of this; we can't find documentation or examples on something that seems so simple.
Thank you!

If you're using Busines Central, you can edit the process model and check the data assignments for the specific REST node. In there you can set the values of the variables or use some process variable to map dynamic values. Hope it helps.
