How to save a task with out form using api

I am using Flowable platform with my own UI. How can I save or complete a task without forns

Are you using the commercial Flowable Platform product? If so, please contact your sales representative for access to the enterprise forum where you can ask enterprise specific question.

Fortunately, because the commercial products use the open source engines, completing a task without a form is essentially the same using the Java API. Here are some docs. Essentially, it comes down to calling the complete on the TaskService with the task id and a map with any variables you want to set.
