Currently there is no way to see VCO transactions, at least form a merchant perspective. Anyone who has access to the developer tool find them, with a callID or an API Key, but merchants won't have access. The merchant doesn't actually see any difference, as they are required to decode the encrypted payload.
Merchant only use VCO to receive customer PAN information. VCO does not process an authorization, much less a capture. The customer must have their own ability to process credit card transactions. VCO only is a delivery mechanism.
