I think that you could use keys %$returnedData->{..}
Not quite. The rule is that it's sigil followed by block returning reference of the appropriate type, but the braces can be left off iff the reference is a simple scalar variable. So you can do keys %$returnedData, but you'd need the braces for keys %{$returnedData->{...}}. Otherwise, it would parse as (keys %$returnedData)->{...}, which is nonsense.
