If an asynchronous transaction was created without setting the auto_confirm flag, this endpoint will have to be called to confirm the transaction. Once successfully confirmed, the transfer order will be submitted to the operator to be processed.
Please note that only unexpired transactions can be confirmed, as denoted in the confirmation_expiration_date field of the transaction. Beyond this, the only allowed change is to cancel the transaction, so as to release the held balance.
