 ## Marking an Application Service as Integration Service
 
 You can mark an application service as an integration service by using the `[IntegrationService]` attribute.
 
-Assume that you have an application service named `ProductAppService`, if you want to mark this application service as an integration service, you should use the `[IntegrationService]` attribute top of the application service class:

+That's all. If you are using the [Auto API Controllers](API/Auto-API-Controllers.md) feature in your application, the URL prefix will be `/integration-api` instead of `/api` for your services. Therefore, you can distinguish internal and external service communications and take additional actions, such as preventing REST API calls for integration services out of API Gateway.

-## Additional Notes
+You can filter integration services (or non-integration services) while creating [Auto API Controllers](API/Auto-API-Controllers.md), using the `ApplicationServiceTypes` option of the `ConventionalControllerSetting` by configuring the `AbpAspNetCoreMvcOptions` as shown below:
+
+```csharp
+Configure<AbpAspNetCoreMvcOptions>(options =>
