Need shoping cart for downloadable products

10+ Year Member

Msg#: 3450 posted 9:56 am on Feb 12, 2005 (gmt 0)

I'm looking for a shopping cart system that can securely sell downloadable products as well as basic physical goods. By secure, I mean:
-Customer is provided with a link, either after checkout on a page or via email, that is only valid for a controlled amount of time
-Customer cannot guess and find other products for sale by manipulating a product URL
-Best case scenario: product link is randomly generated to be unique to each customer's purchase of each product
-Must have preview button for Music Files

Please help, i have looked over 100 - 200 shoping carts, and none of tham have this option. Price is no matter. <snip> Best regards

You often find ecommerce software vendors don't list EVERY permutation of business functionality available. I suggest you actually contact sales reps rather than assume. There are plenty of solutions that can accomplish this task.

x_skater, in your place I'd seriously look at the Open Source offerings out there, if only because the way they're licensed under GNU means that they can be freely modified. Often the core developers or others familiar with the particular cart are very capable of creating a custom module to function with it for a specific need. It sounds like you may do best a custom-developed solution, and that would likely be the cheapest, easiest way to get it

An important consideration is that of security, and particularly if there are products being sold as well, it may be that a custom solution such as modifying something Open Source that's got a good track record and other modules and/or hacks already developed (like being search engine friendly, etc.) is a viable way to go.

One thing I've noticed mentioned around is that security patches are quickly done with Open Source software, simply because of the widespread use and breadth of capability and manpower available for them.

I'll give you some basic facts about this technology as I've implemented softgoods download technology (programming it myself) and implemented it using other products for customer sites.

Secure softgoods downloading isn't typically accomplished with random file names, it's accomplished through software access controlled FTP that requires validation prior to permitting a file to download. The software sold is downloaded via a private non-user accessible/non-browseable area which the user is only granted access to after the customer purchase information has been validated via login and then only per item ordered. If someone didn't order it, it will not permit them to download the file as it validates each item requested against the actual items ordered for that customer.

This blocks any guessing of file names, as only those customers that purchase the products can download the products. Unless someone shares their account information, there won't be any additional downloading either. How additional abuse is typically thwarted is there is a download counter that limits the total downloads per item or the number of days the download is available per customer.

Two off the shelf solutions with softgood downloads that are reasonably priced but vary on total features and control are PDG Commerce and Shopzone.

Good luck!

I agree. That is what we used - limit the download for so many times as well as so many days. This seems to serve its purpose.

You just need to make sure that it is compatible with a few different gateways and Paypal's IPN (if you want to use Paypal)
