fileStreamContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");
form.Add(fileStreamContent, "file", imagename);
form.Headers.ContentType = new MediaTypeHeaderValue("multipart/form-data");
using (HttpClient client = new HttpClient())
{
    client.DefaultRequestHeaders.Add("Authorization", "Bearer yourapikey");

    response.EnsureSuccessStatusCode();
    string responseBody = await response.Content.ReadAsStringAsync();
    return responseBody;
}

Answer 1

I find the problem is that

hd.Name = @"""file""";

hd.FileName = @"""metadata.json""";

The Api have to add this " char in string
