Inbound Shipmethod changes for Amazon Seller Central Integrations

Amazon is changing how shipping methods are passed to ShipWise for Seller Central integrations. This guide explains how to create new FulfillmentServiceLevel mapping rules to maintain automated carrier routing and avoid fulfillment disruptions.

Starting March 2026, Amazon is updating shipping method data for Seller Central NA and UK & EU integrations. This change will impact how inbound ship methods are determined in ShipWise and will require updates to user Marketplace Mapping rules.

What Is Changing
The following changes apply to Amazon Seller Central NA and Amazon Seller Central UK & EU integrations: 

Previously the ShipWise Marketplace Inbound Shipmethod was determined by the combination of the Amazon “ShipmentServiceLevelCategory” (ex: Standard, Expedited, NextDay, FreeEconomy) and the "ShipServiceLevel" (ex: Std US D2D Dom, Exp US D2D Dom, Next US D2D Dom, Econ US Dom)

Amazon will be depreciating the “ShipServiceLevel" field and changing the name of the “ShipmentServiceLevelCategory” field to “FullmentServiceLevel.”

Moving forward the ShipWise Marketplace Inbound Shipmethod will be determined by the Amazon “FulfillmentServiceLevel” field value.

Supported 'FulfillmentServiceLevel' Values
ShipWise supports the following values:

"Expedited"
"FreeEconomy"
"NextDay"
"Priority"
"SameDay"
"SecondDay"
"Scheduled"
"Standard"

 

New Carrier Marketplace Mappings
Inbound Shipmethod mapping rules for Amazon Seller Central should be created for the above “FulfillmentServiceLevel” values.

Users must create new inbound Shipmethod mapping rules for each applicable 'FulfillmentServiceLevel' value.

Additionally, if there are Inbound Return Service mapping rules set then new Shipmethod rules should be created for these as well.


Important: Do Not Delete Existing Mapping Rules

Please do not update or remove any existing Amazon Seller Central Shipmethod mappings. Preexisting unshipped Amazon orders may still reference the deprecated ship methods. Removing those mappings could affect fulfillment for those orders.

What Users Need To Do 
Step by step guide:

  1. Log in to the ShipWise WebApp and navigate to Settings > Marketplace Mappings


  2. Select your Amazon Seller Central integration


  3. Create new inbound Shipmethod mapping rules for each FulfillmentServiceLevel value

     

  4. Save your updates and review that all new ship methods have been added.

     

Note: If you have Saved Advanced Searches or Subscribed Tags that reference deprecated Amazon ship methods, you will need to create new versions aligned to 'FulfillmentServiceLevel' values.

Why This Matters
Marketplace Shipping Method Mapping ensures your Amazon orders route correctly to the appropriate carrier service or service group without manual intervention.

Updating these mappings will help prevent:

  • Incorrect carrier selection

  • Manual intervention during fulfillment

  • Shipping delays

  • Operational exceptions in high-volume workflows

For enterprise fulfillment and 3PL teams, maintaining accurate service mappings is critical to keeping automated shipping rules functioning as expected.
