i working with netcore 2.1 and identityserver4 with Resource owner password flow

i need to get the client_id that generate the token bearer in one request
exist one way to get the client_id?
exist the relation in database userId,token,client_id?
the problem is that i not know what client_id make the request

i have a API in net core, multiple databases and multiples clients, in function of client_id i get information a database

By default , the access token issued from identity server 4 includes client_id claim:

After the client send request to your web api with access token , on web api side , add the authentication services to DI and the authentication middleware to the pipeline:

1.Add IdentityServer4.AccessTokenValidation NuGet package to your project

2.Update Startup to look like this:

 public void ConfigureServices(IServiceCollection services)

{

    services.AddMvcCore()

        .AddAuthorization()

        .AddJsonFormatters();



    services.AddAuthentication("Bearer")

        .AddIdentityServerAuthentication(options =>

        {

            options.Authority = "http://localhost:5000";

            options.RequireHttpsMetadata = false;



            options.ApiName = "api1";

        });

}



public void Configure(IApplicationBuilder app)

{

    app.UseAuthentication();



    app.UseMvc();

}

Then you can get the claims which include the client id :
