Basically, you create a key list with Serial Numbers which are uploaded to the shop. After the order process, a Serial Number key from this key list is inserted in the order confirmation e-mail and the customer can download your protected multimedia file.

 

If you sell a network license where each order can contain a different quantity of licenses, it is not possible to work with uploaded keys. You have to create a Serial Number Key which is different per order and includes the quantity of licenses ordered.

 

Both scenarios are described for Avangate, cleverbridge and Element5 / Share-it!.
