I’m located in Germany and am developing a skill for German and English speaking locales.
Is there any way to test in-skill purchasing from outside the US? I know that this feature is only available in the US, but even in development mode every product is marked as NOT_PURCHASABLE.
Even after creating a developer account at amazon.com (instead of amazon.de) and moving the skill there, purchasing a product still fails, both in the developer console and on a physical device (which is connected to the US account). Based on my research, the account must also have a valid postal address in the US. But even after entering a fake US address it didn’t work for me.
So, is there any way to test in-skill purchasing if you're not in the US? There should be :)
