Hi,

Thank’s for tutorial it’s interresting, but if i can expose my opinion, only show how to used in Blazor app is not enough, secure and after didn’t have a concret sample for calling API, it’s quite “useless” ? Sorry if words is too hard, but for some it’s blocking, because having API for data and cannot be call ?

For my part i’ve used :

 builder.Services
                .AddAuth0WebAppAuthentication(options =>
                {
                    options.Domain = builder.Configuration["Auth0:Domain"];
                    options.ClientId = builder.Configuration["Auth0:ClientId"];
                    options.ClientSecret = builder.Configuration["Auth0:ClientSecret"];
                })
                .WithAccessToken(options =>
                {
                    options.Audience = builder.Configuration["Auth0:Audience"];
                });


app.MapForwarder("/{**catch-all}", "https://localhost:5000", transformBuilder =>
            {
                transformBuilder.AddRequestTransform(async transformContext =>
                {
                    var accessToken = await transformContext.HttpContext.GetTokenAsync("access_token");
                    transformContext.ProxyRequest.Headers.Authorization = new("Bearer", accessToken);
                });
            }).RequireAuthorization();

If i’ve connected and go manualy on /api/my-url it’s forward with AccessToken
If i try from HttpClient from Page it’s try to call auth flow :frowning:

Kr,
