Make changes to an existing task

To update a task in Box you will need to call the PUT /tasks/:task_id API with the ID of the task. This API can be used to change the action type of the task, add a message, or change the due date.

cURL
curl -i -X PUT "https://api.box.com/2.0/tasks/12345" \
     -H "Authorization: Bearer <ACCESS_TOKEN>" \
     -H "Content-Type: application/json" \
     -d '{
       "action": "review"
     }'
.NET
var updates = new BoxTaskUpdateRequest()
{
    Id = "22222",
    Message = "Could you please review this?"
};
BoxTask updatedTask = await client.TasksManager.UpdateTaskAsync(updates);
Java
BoxTask task = new BoxTask(api, "id");
BoxTask.Info info = task.new Info();
info.setMessage("An edited message.");
task.updateInfo(info);
Python
task_update = {'message': 'New Message', 'due_at': '2014-04-03T11:09:43-10:00'}
updated_task = client.task(task_id='12345').update_info(data=task_update)
print(f'New task message is {updated_task.message} and the new due time is {updated_task.due_at}')
Node
client.tasks.update('11111', { message: 'Could you please review?' })
	.then(task => {
		/* task -> {
			type: 'task',
			id: '11111',
			item: 
			{ type: 'file',
				id: '22222',
				sequence_id: '0',
				etag: '0',
				sha1: '0bbd79a105c504f99573e3799756debba4c760cd',
				name: 'box-logo.png' },
			due_at: '2014-04-03T11:09:43-07:00',
			action: 'review',
			message: 'Could you please review?',
			task_assignment_collection: { total_count: 0, entries: [] },
			is_completed: false,
			created_by: 
			{ type: 'user',
				id: '33333',
				name: 'Example User',
				login: 'user@example.com' },
			created_at: '2013-04-03T11:12:54-07:00' }
		*/
	});

Task actions

Box currently supports two types of tasks defined by the action value: review tasks and complete tasks.

The type of task determines the possible resolution states a task can be in and the interface shown to a user in the web and mobile apps.

Task actionPossible resolution states
reviewincomplete, approved, rejected
completeincomplete, complete

A review task starts out in an incomplete state and can be marked as incomplete, approved, or rejected. In the user interface a user is provided with a text box and an pair of buttons to approve or reject the task.

A complete task starts out in an incomplete state and can be marked incomplete or completed. Once a this task is marked completed, no further changes can be made to the task's state. In the user interface a user is provided with a text box and an button to mark the task as completed.

Completion rules

A task on a file can be assigned to more than one collaborator on the file, and a task has a completion_rule that can be used to define if all users who've been assigned the task (all_assignees) or only one assignee (any_assignee) need to complete the task.
