Checking if user has an amazon account or not for subscription payment
Hi , Sorry if my question is inappropriate. I am so new on Amazon. I am trying to integrate In app purchasing into my existing app. I already have many signed up users. And whenever my user wants to subscript to my app I am using just Amazon payment on Fire TV. Even my user does not have an amazon account api gives successful message however payment is having pending status. Is there any way to check if a user has an amazon account that is enabled for payment or not ? Thank you for your help.
