+The client-side flow returns the access_token and expires_in in the URI's
+fragment, and does not provide a refresh_token. However, if the user denied
+access then the error is returned in the URI's query. The URIs look like this:
+  - <get_redirect_uri>?#access_token=...
+  - <get_redirect_uri>?error=access_denied...#_=_
