Howssl API uses the status field in the response to express the processing status of the request. When status value is false, msg field will be returned to mark the error details. Some common errors will return code value to mark the rough type of errors. Business error means when the request is wrong, the wrong response will also be returend via the form of JSON. For example, { "status":"false", "code": 501, "msg": "The operation needs the correct Token. Please verify your Token" }
