I'm trying to submit an assignment via the API using C#. I have the file uploaded to the user's folder and now I need to link the file (with id =28386) to the assignment (id=1855) but I get a status code 400 : "Bad Request" because of "No valid file ids given". I think it's the same issue as in Submit Assignment via API
This is my code:
Dictionary<string, string> vars = new Dictionary<string, string>();
vars.Add("comment[text_comment]", "My comments here");
vars.Add("submission[file_ids]", "28386"); // also tried without the ''
var p1Content = new FormUrlEncodedContent(vars.ToArray());
using (HttpResponseMessage response = await httpPOST(baseUrl, "/api/v1/courses/330/assignments/1855/submissions", accessToken, p1Content))
Many thanks in advanced for your help
