send a Post HTTPRequest to a Identity Check company

问题

I am trying to send a Post HTTPRequest to a Identity check company. I created JSON file and tested the file using SOAPUI and I got the response back using SOAP UI. I tried to send the same JSON file using my code below:

public void test()
    {
        string Hmackey = "XXXXX";
try
        {
                HttpClient client = new HttpClient();
                client.BaseAddress = new Uri("https://test");
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));//ACCEPT header
                client.DefaultRequestHeaders.TryAddWithoutValidation("hmac-signature", Hmackey);
                HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "relativeAddress");
                request.Content = new StringContent(JSONstring,
                                                    Encoding.UTF8,
                                                    "application/json");//CONTENT-TYPE header
                                                                        // var response = client.SendAsync(request).Result;

                var response = client.SendAsync(request).GetAwaiter().GetResult();

            }

I got the following response back. Below is from immediate window:

{StatusCode: 404, ReasonPhrase: 'Not Found', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  X-OneAgent-JS-Injection: true

}
    IsSuccessStatusCode: false
    ReasonPhrase: "Not Found"
    RequestMessage: {Method: POST, RequestUri: 'https://test', Version: 1.1, Content: System.Net.Http.StringContent, Headers:

  Accept: application/json
  hmac-signature: XXXXX
  Content-Type: application/json; charset=utf-8
  Content-Length: 3176
}}
    StatusCode: NotFound
    Version: {1.1}

Below is my JSON file. IN C#, it has lot of "/r/n" and "/". I cleaned up the JSON file for clarity, but when I am sending my JSOn file to the client, it has all "/r/n" and "/"

    }
}

I also saw this answer, but in my case the URL is not changing:

https://stackoverflow.com/questions/16130908/statuscode-404-reasonphrase-not-found-version-1-1

Per the Identity check company, I am supposed to include three headers in my JSON Request:

Accept:application/json
Content-Type:application/json
hmac-signature:<TheCalculatedHMACSignature>

any help will be greatly appreciated
