Blazor WebAssembly Apps with Multiple Audience

Help

Hi Team,
My scenario is - I have two API which means I have two audience created in Auth0 dashboard. And both APIs are working as expected.

However, when I am trying to invoke those APIs from Blazor WASM one of the API fetching data and the other one is getting invalid audience.

I am using .NET 6 where Team introduced AdditionalProviderParameters so for one of API I have added -

builder.Services.AddOidcAuthentication(options =>
{
    builder.Configuration.Bind("Auth0", options.ProviderOptions);
    options.ProviderOptions.ResponseType = "code";
    options.ProviderOptions.AdditionalProviderParameters.Add("audience", "https://quizapi.sarkaran.ml/");
    
});

Which seems to be working fine. However When I am adding another audience, it starts failing -

builder.Services.AddOidcAuthentication(options =>
{
    builder.Configuration.Bind("Auth0", options.ProviderOptions);
    options.ProviderOptions.ResponseType = "code";
    options.ProviderOptions.AdditionalProviderParameters.Add("audience", "https://quizapi.sarkaran.ml/");
    options.ProviderOptions.AdditionalProviderParameters.Add("audience", "https://weatherforecastapi.sarkaran.ml/"); // <- That seems to be not working.

});

I have tried by setting Default Audience from Setting as well, but no luck. So my question is in case I need to call more than API how to set the audience?

Hey @ankt.srkr, multiple audiences are not supported. See here.
