Due Dates for Dicussion/Graded Checkpoints?

[windir19]

For more information on discussion checkpoints check this out. In short: it now allows a bunch of new features for grading and adding 2 due dates for discussions for initial posts and replies.

I know that the typical due date attribute for discussions in python is something like discussion.due_at_date but I can't find or figure out the attribute names for the new "Reply to Topic Due Date" or "Required Replies Due Date". (Screenshot below with settings in Canvas) Are these even attributes that are associated with the Assignment class for CanvasAPI or has that not been added in yet?

It looks like you can get these values via the DiscussionTopic object. Specifically, if it is acquired through the standard GET endpoint.

Here's some super basic code example

course = canvas.get_course(COURSE_ID)
discussion_topic = course.get_discussion_topic(DISCUSSION_TOPIC_ID)
print(discussion_topic.assignment["checkpoints"])

yields

[
    {
        "due_at": "2026-02-15T04:59:59Z",
        "lock_at": None,
        "name": "Test Graded Discussion Checkpoints",
        "only_visible_to_overrides": False,
        "overrides": [],
        "points_possible": 0.0,
        "tag": "reply_to_topic",
        "unlock_at": None,
    },
    {
        "due_at": "2026-02-22T04:59:59Z",
        "lock_at": None,
        "name": "Test Graded Discussion Checkpoints",
        "only_visible_to_overrides": False,
        "overrides": [],
        "points_possible": 0.0,
        "tag": "reply_to_entry",
        "unlock_at": None,
    },
]

I tried getting the same information from the Assignment object but wasn't able to. If there's an include[] param that does the trick, it's not in the Get a single assignment docs at time of writing.

Thank you for your help @Thetwam!

So it is a part of DiscussionTopic! That makes sense. But now I have 2 other questions:

It looks like for each there is the due date attribute due_at but then to differentiate whether it is a due date to "reply to the topic" or "reply to entry" you have the tag attribute that says reply_to_topic and reply_to_entry.

1. In my script if I wanted to change the due date for an all assignments/discussions/quizzes I would change it like this assignment.edit(assignment={'due_at':due_date}), how would I do the same thing for a discussion topic depending on the tag since some how I need to change 'due_at' based on 'tag'?
2. Given the way my script for shifting Spring Break dates works now by adjusting the all of the assignments/discussions/quizzes due dates with assignment.edit(assignment={'due_at':due_date}), I am probably going to have to treat discussions with checkpoints differently as opposed to regular discussions differently. What can I do to check to see if an assignment is a regular discussion with out checkpoints so I am not shifting the dur date twice?

Thank you again for your help @Thetwam!
