Follow these steps configure your eBay integration.
Verify account requirements
PackageBee automated fulfillment for eBay requires that you have a Selling Manager or Selling Manager Pro eBay account.
For more information about these account types, see eBay: Selling Manager and Selling Manager Pro.
Configure product SKUs
Stock keeping units (SKU) are merchant-defined codes that uniquely identify products in a warehouse. It is critical that the SKUs defined in eBay exactly match the SKUs loaded into your fulfillment provider's warehouse management system.
