# Sharing a transfer

## POST /transfer/share

> Shares an existing transfer with 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). Sharings does not add new recipients to an existing transfer. Instead it only sends out download links. When sharing with an existing recipient - they will receive their original tracked download  link again. When sharing with new recipients - they will receive the general (non-tracked) download link.
