Provide ability to check in-skill subscription status from external application
Our service has multiple frontends. For this example, let's assume we have an Alexa Skill and Web interface.
CASE 1: User subscribes via Web and uses the Web. OK
CASE 2: User subscribes via skill and uses the skill. OK
CASE 3: User subscribes via the Web and users the skill. OK (The skill can check the payment API of the web application for sub status.)
FAIL CASE: User subscribes via Alexa skill and uses the web app. There is no way for the web application to verify the Alexa skill subscription status.
Please add this.
