Overview

Amazon fully transitioned its FBA shipment creation process to the Send to Amazon workflow, retiring the legacy Seller Central shipping queue and replenish inventory system. This change affects every seller who ships inventory to Amazon's fulfillment centers, requiring them to use the updated workflow or compatible APIs for all new shipment creation.

Key Points / What Sellers Need to Know

• Legacy workflow fully retired — The old shipment creation and replenish inventory workflow has been completely replaced by Send to Amazon across all Amazon stores.
• Mandatory transition completed — As of September 30, 2022, sellers can no longer view, edit, or complete any shipments that were created through the previous workflow.
• Two creation methods available — All new FBA shipments must be created either through the Send to Amazon interface in Seller Central or through Amazon's Selling Partner API (SP-API).
• Case-pack templates introduced — Sellers can now create reusable case-pack templates that store box content information along with prep and labeling details for single-SKU boxes.
• Mixed-SKU box support — The updated workflow allows sellers to include both single-SKU and mixed-SKU boxes within the same shipment workflow, providing greater flexibility.

How the Transition Worked

Amazon rolled out the Send to Amazon workflow as a replacement for the aging shipment creation system that sellers had used for years. The initial cutover date was March 17, 2022, when Send to Amazon became the required method for creating new FBA shipments. Amazon provided a grace period through September 30, 2022, during which sellers could still access and manage shipments that had been started under the old system. After that date, all legacy shipments became inaccessible, and any in-progress shipments created through the old workflow could no longer be edited or completed.

This transition applied across all of Amazon's global marketplaces, meaning sellers operating in multiple stores needed to adapt to the new interface regardless of which region they sell in. Sellers who relied on the API for shipment creation were directed to use the updated Fulfillment Inbound API endpoints that align with the Send to Amazon workflow.
