  • Synchronize your local systems with your FBA inventory availability. You can identify and retrieve real-time inventory availability updates for items where availability might have changed. For more information, see Monitor inventory availability with the Inventory API section.
  • Get detailed availability status of for specified items. You can get detailed availability information for items that you specify, including the earliest availability to pick from inventory. You can also find out whether items are in an Amazon fulfillment center, in an inbound shipment to a fulfillment center, or being transferred between fulfillment centers.
