Other Attributes

There are additional attributes that may be accessed that we have not documented. Please take a look at the Azure documentation. Any attribute in the response may be accessed with the key names separated by dots (.).

The API may not always return keys that do not have any associated data. There may be cases where the deeply nested property may not have the desired attribute along your call chain. If you find yourself writing tests against properties that may be nil, fork this resource pack and add an accessor to the resource. Within that accessor you’ll be able to guard against nil keys. Pull requests are always welcome.
