How to get all re-submissions of an assignment

[hdelrio]

In the API documentation there is not a clear way to request all the submissions, including resubmissions, a student has made on an assignment. There is information on how many attempts the student has made (which some how let me know how many submissions + re-submissions the student has made). 

I know it is possible since when as an instructor I attempt to grade the submissions the student has made I can select based on timestamp the submission to grade.

Add ?include[]=submission_history to the submission endpoint.

For example:

   .../api/v1/courses/123/assignments/456/submissions/sis_user_id:nktest?include[]=submission_history
