I've installed the UmbracoCms.RestApi package, Changed my Web.Config to look at the UmbracoStandardOwinStartup class.

I've also changed my UmbracoStandardOwinStartup class to this :

app.ConfigureUmbracoRestApi(new UmbracoRestApiOptions()
        {
            //Modify the CorsPolicy as required
            CorsPolicy = new CorsPolicy()
            {
                AllowAnyHeader = true,
                AllowAnyMethod = true,
                AllowAnyOrigin = true
            }
        });

        app.UseUmbracoBackOfficeTokenAuth();

I am using postman to get the token via umbraco/oauth/token - Which gives me back a bearer token.... so far so good.

I am next trying to do a GET on umbraco/rest/v1/content, I've added the Authorization header with my bearer token in the form of Bearer (then the token).

However for every request i am getting the "Authorization has been denied for this request." but i'm not sure why!? Can anyone point me in the right direction?
