Tasks are internal assignments that you can bill to accounts if necessary. When working with tasks in the API, use the TaskService class.
The API provides the following model interfaces for tasks:
•The Task class, which contains information about the task.
•The TaskAssignee class, which contains information about the user assigned to a task.
•The TaskPriority class, which contains the enums that indicate the priority of the task.
•The TaskWorkStatus class, which contains the enums that indicate the status of the task.
Refer to the TaskService samples for examples of working with tasks in the API.
