Is there a way to 'Add to Cart' from a link from an external website using a query string
Hello,
We have an external website (non php) which we would like to allow to add unique products into the ecart shopping cart and check out. Is there a way to add products to the cart using a link to the cart.php page with a query string containing the ProductName, ProductSKU, ProductPrice and ProductQuantity. The products would not necessarily be in our products database.
