+> [!IMPORTANT]
+> * API Management support for private endpoints is currently in **preview**.
+> * To enable private endpoints, the API Management instance can't already be configured with an external or internal [virtual network](../articles/api-management/virtual-network-concepts.md).  
+> * During the preview period, a private endpoint connection supports only **incoming traffic** to the API Management instance. Outbound traffic isn't supported.
