You host an on-premises ASP.NET Web API at the company headquarters. The Web API is consumed by applications running at the company's branch offices using the Azure Relay service. All the users of the applications are on the same Azure Active Directory (Azure AD).
You need to ensure that the applications can consume the Web API.
What should you do?
To begin using Service Bus messaging entities in Azure, you must first create a namespace with a name that is unique across Azure. A namespace provides a scoping container for addressing Service Bus resources within your application.
When you publish an application through Azure Active Directory Application Proxy, you create an external URL for your users to go to when they're working remotely. This URL gets the default domain yourtenant.msappproxy.net.
