I want to download the zip file of all students' assignment submissions. From the API, we get the follow data. But this url is not to a file ("submissions_download_url":"https://[domain]/courses/:coursesID/assignments/:assignmentsID/submissions?zip=1"). When I try to open this page, my API token becomes useless.
So my question is: Who works out that how to download the zip file of all students' assignment submissions. What I should to do?
I am using C++. Thank you.
