Looking at the redirect code on DonationForm.js, looks like we are not passing the contact_id/contact_hash to the payments url. Passing the contacts' id/hash would help our push towards understanding how new contact records are created especially from email campaigns.

Seeing that DonationInterface has part of the code that references these parameters, is it possible that they were removed from the redirect parameters recently for good reasons? If not, could we add the fields to the redirect parameters?

Thanks.
