Your eBay Payment Policy specifies how customers will pay for your eBay items.
Set up your Payment Polices on eBay's site. Once logged into eBay, select Account Settings from the drop-down beside your name in the upper-right corner of the page. Then click the Business Policies link. Select Create then select Payment. Create and save the Payment policy.
When the list of policies is displayed, click the title of Payment Policy that you wish to use for the listings you create using the plug-in. When the edit page is displayed, the Payment Profile ID will be displayed in your browser's address bar. Look for "profileId=xxxxxxxxxxxx" in the URL. The number is the Payment Profile ID to enter into the Configuration Options of the plug-in.
