 ## Microsoft identity platform for web API calls
 
-Blazor Web Apps that use use [Microsoft identity platform](/entra/identity-platform/)/[Microsoft Identity Web packages](/entra/msal/dotnet/microsoft-identity-web/) for [Microsoft Entra ID](https://www.microsoft.com/security/business/microsoft-entra) can make streamlined calls using Entra-specific API. This approach is used by the `BlazorWebAppEntra` and `BlazorWebAppEntraBff` sample apps described in the *Sample apps* section of this article.
+Blazor Web Apps that use use [Microsoft identity platform](/entra/identity-platform/)/[Microsoft Identity Web packages](/entra/msal/dotnet/microsoft-identity-web/) for [Microsoft Entra ID](https://www.microsoft.com/security/business/microsoft-entra) can make streamlined web API calls with API provided by the [`Microsoft.Identity.Web.DownstreamApi` NuGet package](https://www.nuget.org/packages/Microsoft.Identity.Web.DownstreamApi).
+
+[!INCLUDE[](~/includes/package-reference.md)]
+
+In the app settings file (`appsettings.json`), provide a base URL and scopes. In the following example, the `{BASE ADDRESS}` placeholder is the base URL of the web API. A single scope is specified with an App ID URI (`{APP ID URI}` placeholder) and scope name (`{SCOPE NAME}` placeholder):
+
+```json
+"DownstreamApi": {
+  "BaseUrl": "{BASE ADDRESS}",
+  "Scopes": [ "{APP ID URI}/{SCOPE NAME}" ]
+}
+```
+
+Example:
+
+```json
+"DownstreamApi": {
+  "BaseUrl": "https://localhost:7277",
+  "Scopes": [ "api://11112222-bbbb-3333-cccc-4444dddd5555/Weather.Get" ]
+}
+```
+
+In the app's `Program` file, call:
+
+<!-- UPDATE 10.0 - Missing API doc for 'AddDownstreamApi' -->
+
+* <xref:Microsoft.Identity.Web.MicrosoftIdentityWebApiAuthenticationBuilder.EnableTokenAcquisitionToCallDownstreamApi%2A>: Enables token acquisition to call web APIs.
+* `AddDownstreamApi`: Adds a named downstream web service related to a specific configuration section.
+* <xref:Microsoft.Identity.Web.TokenCacheProviders.InMemory.InMemoryTokenCacheProviderExtension.AddInMemoryTokenCaches%2A>: Adds both the app and per-user in-memory token caches.
+
+```csharp
+builder.Services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
+    .AddMicrosoftIdentityWebApp(builder.Configuration.GetSection("AzureAd"))
+    .EnableTokenAcquisitionToCallDownstreamApi()
+    .AddDownstreamApi("DownstreamApi", builder.Configuration.GetSection("DownstreamApi"))
+    .AddInMemoryTokenCaches();
+```
+
+Inject <xref:Microsoft.Identity.Abstractions.IDownstreamApi> and call <xref:Microsoft.Identity.Abstractions.IDownstreamApi.CallApiForUserAsync%2A> when calling on behalf of a user:
+
+```csharp
+internal sealed class ServerWeatherForecaster(IDownstreamApi downstreamApi) : IWeatherForecaster
+{
+    public async Task<IEnumerable<WeatherForecast>> GetWeatherForecastAsync()
+    {
+        var response = await downstreamApi.CallApiForUserAsync("DownstreamApi",
+            options =>
+            {
+                options.RelativePath = "/weather-forecast";
+            });
+
+        return await response.Content.ReadFromJsonAsync<WeatherForecast[]>() ??
+            throw new IOException("No weather forecast!");
+    }
+}
+```
+
+This approach is used by the `BlazorWebAppEntra` and `BlazorWebAppEntraBff` sample apps described in the *Sample apps* section of this article.
