// Sample JSON response:
// (Sample code for parsing the JSON response is shown below)

// If the envelope you're trying to send is not yet completed, you'll get an error such as this:
// {
//   "errorCode": "ENVELOPE_IS_INCOMPLETE",
//   "message": "The Envelope is not Complete. A Complete Envelope Requires Documents, Recipients, Tabs, and a Subject Line."
