Both links are certainly relevant, but perhaps the fact that you only got a "redirect" to one of them is not meaningless. Let's wait for other suggestions.

those links are only for reference (perhaps they are not pertinent?)
however the second link seems to be a redirect from 'Responsabile del Provvedimento amministrativo'

Just a hint Of course you have to translate the source text, i.e. the exact expression which "appears before the signature of the issuing authority", rather than the two wikipedia links that you have provided. But you will notice that such expression does not appear in either of those links...
