An error response is generated when any of the required parameters is not specified correctly or any other technical error exists. The error response will indicate an error code along with the actual error message.

A typical Error Response is:

{ 
"response": {
  "id": "105",
  "phone": "",
  "details": "The phone number \"666\" is not a valid phone number", 
  "status": "error"
            }                         
}
