String authStr = myUsername + ":" + myPassword;
String authEncoded = Base64.getEncoder().encodeToString(authStr.getBytes());

OutputStreamWriter out = new OutputStreamWriter(request.getOutputStream());
out.write(myData);

// 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);
