The Execute Task Action REST API sets a task back to the workflow for further processing. Each task type has a set of task actions and a workflow that specifies the sequence of tasks. When you execute a task action, the task moves to the next step in the workflow. If a task action does not have a subsequent task, the workflow terminates when you execute the task action.
The API uses the POST method to perform actions, such as approve, escalate, or cancel a task.
