Learning Object Dates

Welcome to Our New API Docs! This is the new home for all things API (previously at Canvas LMS REST API Documentation).

Learning Object Dates API

API for accessing date-related attributes on assignments, quizzes, modules, discussions, pages, and files. Note that support for files is not yet available.

A LearningObjectDates object looks like:

{
  // the ID of the learning object (not present for checkpoints)
  "id": 4,
  // the due date for the learning object. returns null if not present or
  // applicable. never applicable for ungraded discussions, pages, and files
  "due_at": "2012-07-01T23:59:00-06:00",
  // the lock date (learning object is locked after this date). returns null if
  // not present
  "lock_at": "2012-07-01T23:59:00-06:00",
  // the reply_to_topic sub_assignment due_date. returns null if not present
  "reply_to_topic_due_at": "2012-07-01T23:59:00-06:00",
  // the reply_to_entry sub_assignment due_date. returns null if not present
  "required_replies_due_at": "2012-07-01T23:59:00-06:00",
  // the unlock date (learning object is unlocked after this date). returns null
  // if not present
  "unlock_at": "2012-07-01T23:59:00-06:00",
  // whether the learning object is only visible to overrides
  "only_visible_to_overrides": false,
  // whether the learning object is graded (and thus has a due date)
  "graded": true,
  // [exclusive to blueprint child content only] list of lock types
  "blueprint_date_locks": ["due_dates", "availability_dates"],
  // whether the learning object is visible to everyone
  "visible_to_everyone": true,
  // paginated list of AssignmentOverride objects
  "overrides": null,
  // list of Checkpoint objects, only present if a learning object has
  // subAssignments
  "checkpoints": null,
  // the tag identifying the type of checkpoint (only present for checkpoints)
  "tag": "reply_to_topic",
  // peer review sub assignment details. If a peer review sub assignment exists,
  // it is returned regardless of the Peer Review Allocation and Grading feature
  // state. If no peer review sub assignment exists, the feature must be enabled
  // to receive a null value; otherwise the key is omitted.
  "peer_review_sub_assignment": null
}

Request Parameters:

Parameter
Type
Description

include[]

Array

Array of strings indicating what additional data to include in the response. Valid values: - "peer_review": includes peer review sub assignment information and overrides in the response. If a peer review sub assignment exists, it is returned regardless of the Peer Review Allocation and Grading feature state. If no peer review sub assignment exists, the feature must be enabled to receive a null value; otherwise the key is omitted. - "child_peer_review_override_dates": each assignment override will include a peer_review_dates field containing the matched peer review override data (id, due_at, unlock_at, lock_at) for that override. The field will be present as null if no matching peer review override exists.

exclude[]

Array

Array of strings indicating what data to exclude from the response. Valid values: - "peer_review_overrides": when include[]=peer_review is also specified, the peer_review_sub_assignment object will not include the overrides array, reducing the response payload size. This is useful when using include[]=child_peer_review_override_dates since the peer review override data is already embedded in the parent assignment overrides. - "child_override_due_dates": prevents the sub_assignment_due_dates field from being included in assignment override responses, even when discussion checkpoints are enabled. This reduces response payload size when checkpoint due date information is not needed.

Returns a LearningObjectDates object.
