 - **Connectors**. Logic Apps uses [connectors](https://docs.microsoft.com/azure/connectors/apis-list) to connect to commonly used services. Logic Apps already has hundreds of different connectors, but you can also create a custom connector.
 - **Azure Service Bus**. [Service Bus](https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-messaging-overview) provides secure and reliable messaging. Messaging can be used to decouple applications and integrate with other message-based systems.
 - **Azure Event Grid**. [Event Grid](https://docs.microsoft.com/azure/event-grid/overview) is a serverless platform that's used to publish and deliver application events.
-- **IP address**. The Azure API Management service has a fixed public [IP address](https://docs.microsoft.com/azure/virtual-network/virtual-network-ip-addresses-overview-arm) and a domain name. The domain name is a subdomain of azure-api.net, such as contoso.azure-api.net. Logic Apps and Service Bus also have a public IP address. However, in this architecture, we restrict access for calling Logic Apps endpoints to only the IP address of API Management (for security). Calls to Service Bus are secured by a shared access signature (SAS).
+- **IP address**. The Azure API Management service has a fixed public [IP address](https://docs.microsoft.com/azure/virtual-network/virtual-network-ip-addresses-overview-arm) and a domain name. The default domain name is a subdomain of azure-api.net, such as contoso.azure-api.net, but [custom domains](https://docs.microsoft.com/azure/api-management/configure-custom-domain) can also be configured. Logic Apps and Service Bus also have a public IP address. However, in this architecture, we restrict access for calling Logic Apps endpoints to only the IP address of API Management (for security). Calls to Service Bus are secured by a shared access signature (SAS).
 - **Azure DNS**. [Azure DNS](https://docs.microsoft.com/azure/dns/) is a hosting service for DNS domains. Azure DNS provides name resolution by using the Microsoft Azure infrastructure. By hosting your domains in Azure, you can manage your DNS records by using the same credentials, APIs, tools, and billing that you use for your other Azure services. To use a custom domain name (like contoso.com), create DNS records that map the custom domain name to the IP address. For more information, see [Configure a custom domain name in API Management](https://docs.microsoft.com/en-us/azure/api-management/configure-custom-domain).
 - **Azure Active Directory (Azure AD)**. Use [Azure AD](https://docs.microsoft.com/azure/active-directory/) or another identity provider for authentication. Azure AD provides authentication for accessing API endpoints by passing a [JSON Web Token for API Management](https://docs.microsoft.com/azure/api-management/policies/authorize-request-based-on-jwt-claims) to validate. Azure AD can secure access to the API Management Developer portal (Standard and Premium tiers only).
