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 -i -X PUT "https://api.box.com/2.0/tasks/12345" \
     -H "authorization: Bearer <ACCESS_TOKEN>" \
     -H "content-type: application/json" \
     -d '{
       "action": "review"
     }'

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.

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.
