Get an outgoing wire transfer payment confirmation

Returns a customer-facing payment confirmation as a PDF for the outgoing wire transfer identified by id.

The document confirms that Weavr sent the funds through the instructed payment rail; it doesn't confirm that the funds have reached the payee's account. It is available only after the transfer reaches COMPLETED. A request made before then, or for a transfer with no confirmation, returns 409. If the transfer was subsequently returned, the document also includes the return details.
