Callback Url in development for OAuth2.0

[KimTim08]

In my web apps, I'm using single page app using Angular

and the callback url is my apps is http://domainname.com/#!/callback-fitbit

when I tried to put in "Register an App" the callback URL, I'm getting this error

• Invalid callback url(s): http://domainname.com/#!/callback-fitbit

That's not a valid redirect URI because it should be "https://" (two slashes).

Also, if you're using the Implicit Grant Flow, you cannot use a URL fragment (#) in your redirect URI, as Fitbit must overwrite it with the OAuth 2 values.
