Not all responses actually follow this format, some will throw a FetchError because the Domino's API is inconsistant with how it handles errors. Sometimes it follows the below JSON, and other times it returns SOAP and yet others HTML Error Pages. It is best to wrap things in try catch if you want to have error handling for invalid requests.

Good response

    dominosAPIResponse: {
        Status: 0
    }

Bad Response

    {
        Status: -1,
        StatusItems: [ { Code: 'MissingCityRegionOrPostalCode' } ]
    }

Non JSON response

It is a shame that the API is not consistant.
