Product Flexiblity + Security:

Locking Down your Add-To-Cart Links and Forms.

Because FoxyCart is fundamentally different in how your products are managed, there is the opportunity for a savvy web user to tamper with your "add-to-cart" links or forms. Though this sounds scary, there is a very advanced solution to this problem: FoxyCart's "HMAC Product Validation".

This is a somewhat technical feature, so the product validation documentation is the best place to learn more, but we are quite proud of this solution. We believe it's the most advanced approach to this type of problem available, and we have scripts to make implementation very easy (for those users who aren't taking advantage of an existing CMS+FoxyCart integration).
