Checkout URL

Apps or AI agents can use the Checkout URL format to create a new cart, add products, and direct a shopper to your BigCommerce storefront’s checkout. Multiple products/variants and their quantities can be added using a single URL. Optionally, you can specify the order source, and any applicable coupon code.

A new cart is created every time the URL is accessed.
