I created custom Alexa Skill with Schedule Appointment template. I want to use my Skill from our website. I think to place tag on our frontend and pass POST /v2/skills/{skillId}/stages/{stage}/invocations to invoke my skill. Through ask-cli i generate my access token and refresh token. My access token has expired and i can`t get new one.
The doc https://developer.amazon.com/de-DE/docs/alexa/smapi/get-access-token-smapi.html page poins to https://developer.amazon.com/docs/login-with-amazon/retrieve-token-other-platforms-cbl-docs.html for refreshing token process.
I used Post https://api.amazon.com/auth/o2/token with client_id and client_secret from my Security Profile`s Web Settigs tab, but the response is 400 Bad Request "error_description": "Not authorized for requested operation"; if i set Authorization Bearer header with my expired token my response is 401 Unauthorized "error_description": "Client authentication failed".
Can you explain how to recive a new access token? I read Alexa skill kit vs Alexa Voice Service and may be Alexa skills is not suitable for web site and i need to prefer Alexa Voice Service?
