Every way found on internet regarding sending a request in C# .NET, and setting a custom header / authorization is only visible in the VS request, but when i check on fiddler it's not there. I don't believe it's a code problem, i think it has to do with something else.
Latest way tried:
        var form = new MultipartFormDataContent();
        form.Add(new ByteArrayContent(fileContent, 0, fileContent.Length), "image", filename);
        HttpRequestMessage message = new HttpRequestMessage(HttpMethod.Post, URL)
        {
            Content = form
        };
        message.Headers.Authorization = new AuthenticationHeaderValue("Basic", AuthCode);
        var response = httpClient.SendAsync(message).Result;
        string apiResponse = response.Content.ReadAsStringAsync().Result;
