If you are selling a virtual product (e.g. software or e-book), you can provide a download file location that will be made available to your customers after purchase. The file location can be any downloadable file, a DNN page or any random URL. File protection is handled by native DNN security. Please see How to create downloadable products for more information
If you need to automatically issue a license key, serial number, password or any code to unlock your virtual product, you can make use of the Storefront's built-in access rights system. Please see Rights for more information.
You can have multiple downloadable items per product simply by compressing your files into a single zip file or by creating implicit bundles. Please see Bundled products for more information.
