The purpose of this service is to get the carrier rate quotes for WFS Preferred Carrier Program - FedEx parcel solution, when inbounding seller items from seller pickup point to Walmart fulfillment centers.
For the shipments sent by FedEx small parcel, you can ship packages up to 150 lb, up to 108" in length, and 165" in length plus girth. (Girth is 2x width + 2x height.). You can ship up to 200 packages per shipment.
This API is in legacy state and will be removed on February 09 2026. We recommend transitioning to the Create Carrier Rate Quote (New) API.
