Could someone help me to figure out the endpoints for Authorization Code Flow. What I want is following endpoints:
Authorization Grant Type: Authorization Code Grant
Access Token URI
Client Authentication Scheme
What I was trying to do is create a Alexa Smart Home Skill work which works with Particle Photon. For this Amazon Alexa Skill Kit needs OAuth2 server which supports Authorization Code Flow. The project is complete and is working fine with Login with Amazon. I am able to control lights using Alexa Smart Home Skill Kit. What I was looking for is to use Particle login and retrieve access token and device id. Since Particle IFTTT channel supports OAuth2, it should work for Amazon also.
Probably @harrisonhjones or othes could help me to figure it out.
