Catalog API Enrollment Status
I hope this is the appropriate place to ask this question. If not, please refer me to the proper place.
I am trying to develop a program that uses the Catalog API to identify dropped courses. When a student enrolls in a course, I can query the API and see the enrollment record. Then new enrollment record has a status of "active".
After a student has dropped a course, I can query the API and the enrollment record is identical, except that the status is now "concluded". I am confused, because according to the API documentation, status should return either active or dropped, not concluded.
Has the string "concluded" replaced "dropped"? Is it possible for an enrollment status to be concluded, but it was not dropped?
