Question

I try to auth user through my app with spotify Web API but I receive this error:

INVALID_CLIENT: Invalid redirect URI

URL:

GET         


        

Answer 1

I use the SpotifyAPI-NET API wrapper by JohnnyCrazy and was having this problem despite adding the URL I specified in my wrapper call to my white list as specified above.

The browser's address bar should show the redirect URL it is using buried in the middle of the string - I found that it was also making a request with "https://accounts.spotify.com:8000/authorize" as the redirect URL - perhaps the wrapper is making 2 API calls, but I found that only by whitelisting both this URL and the one I was specifying would it work for me.
