Incoming traffic to Azure API Management’s gateway can be secured to clients running in a virtual network through Azure Private Link. This will limit access to Azure API Management by assigning a virtual network private IP address to the Azure API Management gateway using Azure Private Link. Previously, only Developer and Premium tiers supported this integration with a virtual network. With this update, you can now integrate to clients in a virtual network privately, using the tiers- Developer, Basic, Standard, and Premium.
