In my skill for account linking I use amazon login service. Everything works fine. When user links his account and next time comes back to the skill I can retrieve access token and information I need about him using it.
My question would be, is it possible to retrieve information about user just after account linking process not on skill launch? Maybe there is an endpoint or something, which I could call using userId to determine if users account is linked and get his token? Maybe it is possible to catch the token during the account linking process?
