Hi Rohit, if I understand you correctly then all you need to do is to create a Service in ThingWorx that the external system can call.

One of the Input parameters into the service will be either String or JSON so your call can pass that into ThingWorx.

yes correct but it has to be "post" request not "get".

I apologize looks like I put the uri for a GET not a POST.

For a POST you would do:

ServerAddress/Thingworx/Things/NameofThing/Services/NameofService?method=post&postParameter=<name of input parameter that gets the post document>&Accept=application/json

(use Accept=text/xml for xml content)

I am getting the following error.

Exception in thread "main" java.lang.RuntimeException: Failed : HTTP error code : 500

  at com.thingworx.http.client.HttpConnectionClient.main(HttpConnectionClient.java:76)

Here is the snippet which does my HTTP Connection.

    http_connection.setInstanceFollowRedirects( false );

    http_connection.setRequestMethod( "POST" );

    //http_connection.setRequestProperty( "Content-Type", "application/x-www-form-urlencoded");

    http_connection.setRequestProperty( "Content-Type", "text/xml");

    http_connection.setRequestProperty( "charset", "utf-8");

    http_connection.setRequestProperty( "Content-Length", Integer.toString( postDataLength ));

  

  

    try( DataOutputStream wr = new DataOutputStream( http_connection.getOutputStream())) {

      wr.write( postData );

    }
