We are setting up the AS2 connectivity with a trading partner and we would be using atom cloud. I know that when we use a local atom, we generate a certificate in Boomi and share the public key with the Trading Partner. But when using Cloud Atom, I see the URL as https://eu.connect.boomi.com /as2/<Account.ID>. Since it is HTTPS, are we not supposed to share the public key with the Trading Partner? If yes, how do we get that?
