- To use access control, you need set the `ACCESS_KEY` in config.json inside plugins/GCAuth. (Optional)
- All payload must be send with `application/json` and Compact JSON format ( without unnecessary spaces )
- Auth endpoint is:
- Authentication Checking : `/authentication/type` (GET) , it'll return `me.exzork.gcauth.handler.GCAuthAuthenticationHandler` if GCAuth is loaded and enabled.
- Authentication Checking : `/authentication/type` (GET) , it'll return `me.exzork.gcauth.handler.GCAuthAuthentication` if GCAuth is loaded and enabled.
- Register: `/authentication/register` (POST)
