Simplified Shipping Settings API overview

Simplified Shipping Settings provides accurate delivery estimates using live- carrier data , and protect on-time delivery Seller Performance Standards. You can configure orders to use manually created templates or Simplified Shipping Settings configurations.

Manually created templates

Manually created templates provide the flexibility to incorporate both free and paid shipping options for all products you sell. Manually created templates require you to manually change each template to respond to carrier and fulfillment center complications. If you choose manually created templates, you can tailor them to ship domestic and international orders.

Simplified Shipping Settings

Simplified Shipping Settings allow sellers to specify their carrier and fulfillment center options or use the recommended configurations based on real-time carrier transit data. The recommended configurations protect your on-time delivery (OTD) Seller Performance Standards and provide customers with positive experiences.

You can choose Simplified Shipping Settings if your items meet the following requirements:

The item offers free shipping for customers.
The order can be shipped to the 48 contiguous states. (If an order ships to anywhere outside of the 48 contiguous states, it must use a manually created template.)

You can migrate existing manually created templates to the new Simplified Shipping Settings configurations.

Your shipping costs

Each Simplified Shipping Settings configuration gives you the flexibility to choose if you want items in a particular configuration to prioritize shipping speed or more economical options. As the Simplified Shipping Settings API requires free shipping for customers, the seller is responsible for covering the shipping costs.

Order fulfillment and carrier preferences

Simplified Shipping Settings provide you with recommended fulfillment centers and carrier options. You can use your own presets instead of the recommendations, but they may cause delays depending on carrier transit conditions. When you use the recommended configurations, you are not accountable for delays caused by your shipping carrier. You can use the GET Simplified Shipping Settings details endpoint to confirm that your ship-from-location and carrier methods are accurate.

On-time delivery Seller Performance Standards protection

Sellers and approved Solution Providers who consistently ship orders on-time, use preset carrier methods, and follow the fulfillment center recommendations can protect their on-time delivery (OTD) performance metrics. When you meet all the requirements below, carrier caused delays will not affect your OTD Seller Performance Standards.

Requirement	Definition
On-time shipping performance metrics are at 100%.	You shipped all orders on or before the estimated ship date (ESD).
The carrier method accuracy performance metrics are at 100%.	You shipped all orders with your selected carrier method.
The ship-from-location accuracy performance metrics are at 100%.	You shipped all orders from the recommended fulfillment center location.
