When APIM is in internal mode , What IP would the backend services see when it’s called ?
An Azure service that provides a hybrid, multi-cloud management platform for APIs.
Answer accepted by question author
@Ritu Raj In Internal mode the API Management gateway and developer portal are accessible only from within the VNET via an internal load balancer. The gateway can access resources within the VNET. Therefore it should be the internal VIP IP.
Thanks @MayankBargali-MSFT .
So the third party backends will see our APIM internal IP address ?
What is the significance of the APIM public IP then ?
@Ritu Raj Yes they should see the Internal IP address assigned to the APIM in case you are using the APIM internal mode. With an internal virtual network, the public IP address is used only for management operations. You can refer to this section on the same document.
