try {
URL obj;
HttpURLConnection conn = null;
String url =“http://host:3000/api/card/”+id;

	obj = new URL(url);
	conn = (HttpURLConnection) obj.openConnection();
	conn.setRequestProperty("Content-Type", "application/json");
	conn.setRequestProperty("X-Metabase-Session", "idSession");
	//conn.setDoOutput(true);
	conn.setRequestMethod("DELETE");

Maybe I’m missing something, how are you authenticating?
