Amazon Marketplace Web Service (MWS) will no longer be available after March 31, 2024. All MWS developers must migrate to Selling Partner API (SP-API) to avoid service disruptions. Refer to the Migration Hub for more information.
The Reports API section is optimized for bulk data reporting and provides asynchronous batching of Fulfillment by Amazon (FBA) inventory data. The Reports API section supports a wide variety of user scenarios, such as support for making replenishment, removal, and repricing decisions; checking inventory levels; researching inventory events; and fulfilling tax obligations.
