## POST /transfer/forward

> Forwards an existing transfer to more recipients. Recipients may be specified using their email address or via contact group names (you need to have these groups defined in the contacts area first). Forwarding adds new recipients to an existing transfer and sends them download links (including tracking data) via email.
