Nash uses HTTP response status codes to indicate the success or failure of your API requests. If your request fails, Nash returns an error using the appropriate status code. In general, there are three status code ranges you can expect:
  • 2xx success status codes confirm that your request worked as expected
  • 4xx error status codes indicate an error because of the information provided (for example, a required parameter was missing)
  • 5xx error status codes are rare and indicate an error with Nash’s end
Example of a failed request: 
{
	"error": {
		"code": "MISSING_RESOURCE",
		"message": "job 'job_123' does not exist"
	},
	"response_status": "404 NOT_FOUND",
	"RequestID": "d97e3f4d-114d-4b77-ae47-9e10c5151424"
}

Possible error codes
