No Instructions on Redirect URI

[tjallo]

Got everything working up to the redirect URI.

Not having used the Spotify API properly before, I am curious what redirect URI I should use.
If I use localhost or (one of) my own domain(s) it does not seem to work.

What URI was used in your testing?

You need to add the same Redirect URL in the Spotify API settings. E.g. https://yourdomain.com and set it as an environment variable. Spotify will open a page https:://yourdomain.com?code=xxxxxxxxxx and you than have to copy the complete URL including the HTTP-Get into the Command Line.

At least that's how it works for me.
