I followed the documentation here to submit a file ...
Uploading Files - Canvas LMS REST API Documentation
The end result is a file added to the user's personal file space, and I got back a file id. I can preview the file and I can download this file.
Then I want to use this file as assignment submission for the same user, which is done by this Canvas API.
Submissions - Canvas LMS REST API Documentation
But I am getting "No valid file ids given" error when calling that API. Can someone point me on the right path?
(code is in C#)
var url = $"https://{CanvasHost}/api/v1/courses/{CanvasCourseId}/assignments/{CanvasAssignmentId}/submissions?as_user_id={CanvasUserId}";
var formData = new Dictionary<string, string>
{
{"comment[text_comment]", "submitted via FST"},
{"submission[submission_type]", "online_upload"},
{"submission[file_ids]", $"{fileSubmissionResult.CanvasFileId}"}
};
Solved! Go to Solution.

I did get it to work, my above code is almost correct, except you need to use this instead.
