Currently all apps at eBay’s app center are only available for ebay.com users. International eBay sellers can’t use the apps through apps.ebay.com.
But we do offer some versions for the apps that are available to all users including our Webstore app, Social Store app and Store Designer app.
So if you have an international eBay seller account and you want to sign up to one of those apps you can do that here:
Store Designer: http://www.storedesigner.org
Social Store: http://www.socialstorepro.org
