I am looking for a shopping cart for a new site that will involve selling digital goods (books) housed on the publishers servers....
Basically the customer would buy the digital item on our site, once the transaction is complete the site would transfer the transaction info to the publisher via a web service call, the publisher would then return a redemption code back to us for the customer to download the product from their server. We would then automatically present the redemption code to the customer via email or a link presented on a confirmation page when the above is complete.
Does anyone have any feedback as to which cart would be able to handle this best/easiest? It would likely be a custom job beyond my abilities and I would need to hire someone to set it up. I have seen good things generally about opencart and cubecart. Ideally it would be fairly easy to work with once the web calls were set up.
