Allows for a cart to be created using BigCommerce cart logic. The existing BigCommerce front end cart can be bypassed.


  • A cart id is the same as a checkout id.
  • A cart can be created by adding an existing catalog item or a custom item.
  • Carts are valid for 30 days from the last modification. This can include creating the cart or editing the cart.
  • Redirect URLs can be generated only from carts created using the Server to Server Cart API. To restore a cart that was created on the storefront, either by a shopper or the Storefront Cart API, first recreate the cart using the Server to Server Cart API.
