```
public interface ProviderService
```
This interface methods are returning either Optional or List. When the underlying Adobe IO http API endpoints are responding with `404`, these methods will return empty Optional or empty List. When the underlying Adobe IO http API endpoints are responding with other `4xx` or `5xx` errors, these methods will throw runtime FeignException exposing these error codes. We may work on a more specific error handling as part of https://github.com/adobe/aio-lib-java/issues/7.
