We are using OAuth 2.0 Authorization Code Grant type for Alexa Account Linking. Our application is able to authenticate the user and generate authorization code. After this step Alexa is unable to get the access token from our access token uri. So we are getting "Unable to link the account " error message.
Does anyone know how to debug alexa account linking? Or How to check if alexa is hitting access token uri or not?
Any help or guidance would be appreciated.
