I am trying to submit a task via REST-API .
I always use " /task/{anId}/complete " to submit a task .
But , recently i came across " /task/{anId}/submit-form " which also completes a task .
So , which REST-API is better /complete or /submit-form .
Basically the answer is “it depends on your needs and what is your scenario”
Completes a task and updates process variables using a form submit. There are two difference between this method and the complete method:
If the task is in state PENDING - i.e., has been delegated before, it is not completed but resolved. Otherwise it will be completed.
If the task has Form Field Metadata defined, the process engine will perform backend validation for any form fields which have validators defined. See the Generated Task Forms section of the User Guide for more information.
