URL url = new URL(myURI);
HttpURLConnection request = (HttpURLConnection) url.openConnection();

String authStr = myUsername + ":" + myPassword;
String authEncoded = Base64.getEncoder().encodeToString(authStr.getBytes());
request.setRequestProperty("Authorization", "Basic " + authEncoded);

// we want to use HTTP POST
request.setRequestMethod("POST");
request.setRequestProperty( "Content-Type", "application/json");

// write the data to the request
OutputStreamWriter out = new OutputStreamWriter(request.getOutputStream());
out.write(myData);
out.close();

// try ... catch to handle errors nicely
try {
// make the call to the API
InputStream response = request.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(response));
String replyText;
while ((replyText = in.readLine()) != null) {
System.out.println(replyText);
}
in.close();
} catch (IOException ex) {
System.out.println("An error occurred:" + ex.getMessage());
BufferedReader in = new BufferedReader(new InputStreamReader(request.getErrorStream()));
// print the detail that comes with the error
