Add to Cart form
The "Add to Cart" form enables you to add any number of items to a customer's shopping cart and send the customer to the HAQM retail web site for completing the purchase.
To offer better experience to your visitors, you may want to redirect to HAQM cart page in a new window. This would allow the customer to return to your site post checkout.
Some parameters are optional, but you must specify quantity and at least one of the following parameters: ASIN or OfferListingId. AssociateTag is must for attribution.
To add more than one item to the customer's cart
- Append each set of parameters with a period, then a unique identifier, which establishes a relationship between the parameters (for example,
"ASIN.1=[ASIN]&Quantity.1=1&ASIN.2=[Another ASIN]&Quantity.2=10").
The Add to Cart form works with all locales. Send the Add to Cart form data to one of the following URLs:
