I try to auth user through my app with spotify Web API but I receive this error:
INVALID_CLIENT: Invalid redirect URI
URL:
GET
Navigate to your Spotify developer dashboard and open the project you are working on.
Next click "edit settings" and look for the redirect URIs field.
Put your redirect URI in the field. ex: http://localhost:8888/callback
http://localhost:8888/callback
Click save.
You should be good
