ccvs_return() executes a transaction that has been set up to move funds from the merchant to the customer, as in the case of the customer returning a previously purchased product. session must be a valid session ID as returned by ccvs_init() .

Use ccvs_sale() to move funds in the other direction; that is, from the customer to the merchant.
