Consuming API by sending JSON data format to Third party app using bearer token Authentication by x++ code

HI,

We got an error "The remote server returned an error: (400) Bad Request." while consuming API with third party app. below is my code;

class JSONDeSerialization
{
/// <summary>
/// Runs the class with the specified arguments.
/// </summary>
/// <param name = "_args">The specified arguments.</param>
public void consumeAPI()
{

str destinationUrl = 'https:/www.abc.com', responseJSON;
str token = 'xxxxxxxxx';
System.Net.HttpWebRequest request;
System.Net.HttpWebResponse response;
CLRObject clrObj;
System.IO.Stream requestStream, responseStream;
System.IO.StreamReader streamReader;
System.Exception ex;
System.Net.WebHeaderCollection httpHeader;
System.IO.Stream stream;
System.IO.Stream dataStream;
//System.Net.NetworkCredential Credentials;

try
{

new InteropPermission(InteropKind::ClrInterop).assert();
httpHeader = new System.Net.WebHeaderCollection();
clrObj = System.Net.WebRequest::Create(destinationUrl);
request = clrObj;
httpHeader.Add("Authorization", strfmt("Bearer %1", token));
request.set_KeepAlive(true);
request.set_ContentType("application/json");
request.set_Method("POST");
request.set_Headers(httpHeader);
response = request.GetResponse();
responseStream = response.getResponseStream();
streamReader = new System.IO.StreamReader(responseStream);
responseJSON = streamReader.ReadToEnd();
info(responseJSON);

//JSON deserialatisation

JSONObjectContract jSONObjectContract = FormJsonSerializer::deserializeObject(classnum(JSONObjectContract), responseJSON);
List listdata = new List(Types::Class);
listdata = jSONObjectContract.parmdata();
ListEnumerator listEnumerator = listdata.getEnumerator();
while(listEnumerator.moveNext())
{
EInvoiceDataContract jsonDataContract = listEnumerator.current();
info(strFmt("%1 %2",jsonDataContract.parmIGSTRate(), jsonDataContract.parmIGSTAmount()));
}

//JSON deserialisation

streamReader.Close();
responseStream.Close();
response.Close();

}
catch(Exception::CLRError)
{
ex = CLRInterop::getLastException().GetBaseException();
error(ex.get_Message());
}

}

I need help whether I followed correct code or did I missed anything in code?

Need your help with correct code.
