Invalid redirect URI on spotify auth

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

This is super specific, so make sure you have exact url in each place.

In my app dashboard on spotify I had: http://localhost:3005/

And my url is: https://accounts.spotify.com/authorize?client_id=XXXXXXXXXXXXXXXXX&response_type=code&redirect_uri=http %3A%2F%2Flocalhost:3005/&scope=user-read-currently-playing%20user-top-read

Note the trailing slash in both places.
