Which Appian feature allows developers to retrieve task details and attributes using a Task ID?

The Appian feature that enables developers to retrieve task details and attributes using a Task ID is Task Functions. Task Functions provide a set of capabilities specifically designed for interacting with task data, allowing users to access various attributes associated with a particular task. This includes detailed information such as the task's status, assigned users, and other relevant properties tied to that specific Task ID.

By utilizing Task Functions, developers can efficiently pull in the necessary information they need to display or manipulate tasks within their applications, making it a vital part of the task management process in Appian. This capability is particularly useful when dealing with dynamic task updates or when you need to ensure that the most current information is retrieved for a given task.

Understanding how to leverage Task Functions is crucial for effective task management and user interaction within Appian applications, highlighting their importance in the overall functionality of the platform. Other options do not provide the specific context or functionality associated with retrieving details directly through Task IDs.
