In eBay applications such as ShippingEasy must obtain a user authentication token for each store via the user sign-in and consent process. ShippingEasy is able to obtain this token whenever you connect or reconnect your store.
The user authentication token is required so that eBay can pass orders from your eBay store across to ShippingEasy. As the tokens are only valid for 18 months ShippingEasy will Alert customers 30 days before the expiration date.
NOTE: if you do not update your authentication token before the expiration date then your orders will stop appearing in ShippingEasy. Learn more about eBay authentication tokens.
