Configuring Fees

The fees feature in Carts API allows you to add, update, or remove additional fees beyond the resource price, such as gifting fees, platform fees, and service fees. These fees can be applied at various levels, including the cart, individual items, or fulfillment, providing flexibility in customizing the total cost structure. Optionally, the fees may be taxable.

​

Prerequisites

The following prerequisites must be completed sequentially to configure a fee.

1. Create a cart.
2. Create a fulfillment to apply the fulfillment fee.
3. Create an item to add the item fee.

Fee Initialization

You can apply fees at multiple levels, including the cart, individual items, or fulfillment. The fee resource maintains a consistent structure across all levels. Taxes on fees is controlled by the taxable attribute in the request payload, which defaults to true. This means fees are taxed unless specifically set to false.
