A: This error message would mean that your eBay Keys for Wise Lister are invalid. You'll need to log into Wise Lister and go to eBay API Keys on the left. Click the Disconnect Button. Then click Connect. It will prompt you to log into eBay to authorize the application. Please complete that process. Once done, you'll return to wise lister. Then you can go to Sku Fetch and try to list an item again.
