@jsowalsk For this call you need both the Canvas course ID and user ID, so I believe you can only look it up if you know the specific course and user. I don't think you can use the listing ID here, but you would need to check from the listing which course it is.
In the Canvas Live API the call is under "Course" and called "Get User Progress" and looks like this:
/v1/courses/{course_id}/users/{user_id}/progress
I usually use the API call in my browser, you can replace the bold with your own values:
https://x.instructure.com/api/v1/courses/CourseID/users/UserID/progress
x.instructure.com should be your URL for your environment
CourseID is the course ID, in numbers, such as 101
and UserID is the user ID, also in numbers, such as 102
Hope this helps! We have found it very useful for troubleshooting certificates.
