Overview 

ClickBank Cart is a feature that allows customers to purchase multiple products in a single order. Sellers can configure a payment link that specifies the products and quantities to be purchased on the order form. When the customer arrives at the order form, it displays the items and quantities. Learn more about Vendor-Enabled features here.

When customers make the purchase, they receive a single confirmation email with the details for each product. Customers can request refunds on any of the items individually.

A cart order can include products of any type, and can use a customized order form. Cart orders are compatible with other ClickBank features as described in the Compatibility section. If an affiliate drives a cart sale, their commission percentage is calculated separately for each product in the order.

Benefits of Cart

Cart provides many benefits, including:

• The ability for a customer to purchase multiple quantities of a single product, or multiple products within a single transaction
• An increase in average customer transaction value
• A smoother overall shopping experience, including a seamless integration with your existing storefronts
• The ability to combine cart purchases with additional ClickBank functionality including PitchPlus Upsell Flows, Order Bump, and coupons

Customer View

When a customer follows a cart payment link, the order form displays the cart contents including quantity. For example:

Implementing Cart With the Cbitems Parameter

You can implement cart by creating a payment link that includes the cbitems parameter. This payment link contains the product number of the desired products and their quantities in the cbitems parameter. When the customer follows the payment link, they are taken to an order form that includes the specified items and quantities.

A cart payment link with the cbitems parameter uses the following format:

https://VENDORNICKNAME.pay.clickbank.net/?cbitems=PRODUCTNUMBER.quantity_PRODUCTNUMBER.quantity

The cbitems parameter indicates the items purchased and their quantities using one or more product number-quantity pairs. When the customer arrives at the order form, it displays the items and quantities. 

Code Example

The following payment link example takes a customer to the order form with one item (product number A) and two of another item (product number B).

Compatibility  

Instant Notifications

Instant Notifications version 6 includes line item level details. See the Instant Notification Service article for information about configuring and using Instant Notifications.

APIs

The Orders and Ticket APIs support accessing information from multi-line transaction orders. For the following endpoints, a SKU (item or product number) is provided to request a specific line item. A SKU is required when making a call against a multi-line transaction purchase. If an SKU is not provided, the endpoint will return an error status with a detailed error messaging that a sku is required to return the results of the API call. See the ClickBank APIs article for service descriptions.

PitchPlus Upsell Flows

Cart purchases can be used with the cbfid parameter to initiate PitchPlus upsell flows. See the PitchPlus Upsell Flows article for more information.

Physical Products

Cart supports physical products. If a physical product has shipping and handling charges, the shipping and handling amount is applied linearly with the quantity of products purchased, unless you have configured flat rate shipping. See the Selling Physical Products article for more information about this product type.

Recurring Products

Cart supports recurring products. See the Selling Recurring Products article for more information about this product type.

Coupons

Cart supports coupons. Depending on the coupon's settings, it can be applied to the largest line item in the cart order, or to every product in the cart order. See the Coupons article for more information.

Order Bump

One or more Order Bump products can be displayed on a Cart order form. Any product configured as a bump product for the first product in the cart is also displayed as a bump product for the cart order. See the Order Bump article for more information.
