Hi Ankur,
I was able to get response from the call with status 200, but not able to parse the response using the code below

using namespace HTTP::Client; using namespace HTTP::MessageHeader; using namespace GS::IBinaryChannelUtilities; IO::URI::URI connectionUrl ("https://identity.thenbs.com/"); ClientConnection clientConnection (connectionUrl); clientConnection.Connect (); Request postRequest (Method::Post, "/core/connect/token"); GS::UniString clientID = "user"; GS::UniString clientSecret = "pass"; // More information on the API, and on getting an API key: // https://toolkit.thenbs.com/articles/for-software-developers/#bimToolkitAPI RequestHeaderFieldCollection& headers = postRequest.GetRequestHeaderFieldCollection (); Authentication::BasicAuthentication auth (clientID, clientSecret); auth.HandleRequestHeaderFieldCollection (headers); headers.Add (HeaderFieldName::ContentType, "application/x-www-form-urlencoded"); GS::UniString postBody = "scope=bimtoolkitapi&grant_type=client_credentials"; clientConnection.Send (postRequest, postBody.ToCStr (), postBody.GetLength ()); Response response; JSON::JDOMParser parser; JSON::ValueRef parsed = parser.Parse (clientConnection.BeginReceive (response)); DBPrintf ("HTTP %u\n", response.GetStatusCode ()); if (response.GetStatusCode () == StatusCode::OK) { JSON::ObjectValueRef object = GS::DynamicCast<JSON::ObjectValue> (parsed); JSON::StringValueRef tokenValue = GS::DynamicCast<JSON::StringValue> (object->Get ("access_token")); if (tokenValue != nullptr) { GS::UniString token = tokenValue->Get (); DBPrintf ("NBS Token: %s\n", token.ToCStr ().Get ()); } } clientConnection.FinishReceive (); clientConnection.Close (false);

Could you help on this?
