+SMART on FHIR requires that `Audience` has an identifier URI equal to the URI of the FHIR service. The standard configuration of the Azure API for FHIR uses an `Audience` value of `https://azurehealthcareapis.com`. However, you can also set a value matching the specific URL of your FHIR service (for example `https://MYFHIRAPI.azurehealthcareapis.com`). This is required when working with the SMART on FHIR proxy.
 
-Suppose that the URI for your Azure API for FHIR is `https://MYFHIRAPI.azurehealthcareapis.com`. You need to configure a [resource application registration](register-resource-azure-ad-client-app.md) with that identifier URI.
-
-After you set up a resource application, you also need a client application registration. Most SMART on FHIR applications are single-page JavaScript applications. So you should follow the instructions for configuring a [public Azure AD client application](register-public-azure-ad-client-app.md).

 After you complete these steps, you should have:
 
-- A resource application with the identifier URI `https://MYFHIRAPI.azurehealthcareapis.com`, where `MYFHIRAPI` is the name of your Azure API for FHIR instance.
+- A FHIR server with rge audience set to `https://MYFHIRAPI.azurehealthcareapis.com`, where `MYFHIRAPI` is the name of your Azure API for FHIR instance.
 - A public client application registration. Make a note of the application ID for this client application.
