A link token was refused: it is incomplete, was not issued by cogDepot, was made for another purpose (a confirmation link cannot unsubscribe), has expired, or, for a contact e-mail, was issued for an address the account no longer holds. Nothing was changed. Use the link exactly as it was mailed. For an unconfirmed want, register it again; for a contact e-mail, send PUT /v1/account/contact to be mailed a new link.
