Authorization Code Flow - misleading documentation

[benfernandes]

https://developer.spotify.com/documentation/general/guides/authorization/code-flow/#request-a-refres...

The documentation doesn't mentioned that a "refresh_token" is returned in the response when you refresh your access token. This is important because you can only use refresh tokens once and are required to use the newly returned one in the next refresh request.

If I've misunderstood the endpoint, the documentation should at least say that a "refresh_token" is not returned during a token refresh.
