I created an Alexa Smart Home Skill to go enhance my home automation setup. The goal is to look into voice controlling my Raspberry Pi via Alexa. To do so I followed this Amazon developer blog to reach the mandatory account linking between the Alexa skill and an authentication provider. In this case this provider is Login with Amazon (LWA).
However following the instructions and using the skills redirection URL starting with https://pitangui.amazon.com/api/skill/link/.... proved to be utterly unsuccessful and just earned me a very non-descriptive error message. Essentially just saying that it didn't work. Great.
How do I make the LWA work with my Alexa skill?
