How to prefill Flowable forms?

I have a form that I designed in Flowable modeler. I’m wondering if it’s possible to have some of the fields prefilled when I open it in Flowable tasks with information coming from the backend in form of BPMN variables?

Use process variables as defaults on the form you’re using with your human task and then include a task (I.e. service, http, script …) prior to reaching your human task which will retrieve and set those variables. At that point the values could come from your DB, a REST call, set in a script task etc…
