We've Changed Some Things Around Here
As of 3/29, all marketplace shipping connections between 3D Cart, Allegro, BigCommerce, Etsy, Jet, Magento, Newegg, Overstock, Prestashop, Rakuten, Sears, Shopify, Volusion, Walmart, WooCommerce and Yahoo Shopping have been shut down. You're currently still able to access all your shipping and order history.
Still shipping through Amazon and eBay? You’ll still be able to manage and ship your orders within the UPS marketplace shipping dashboard.
