Not sure if you were able to find an answer on this. While looking at it I found a walkthrough on Github - Logic App sample for automatic traffic diversion for Azure App Service
Is it possible to direct traffic from Front Door to Logic App
Hello, For an Azure Logic App with HTTP request trigger. It generated a POST URL. Is it possible to direct external traffic from an Azure Front Door so that it calls the Logic App as a Backend? The Logic App is not listed when selecting 'App Services ' as a Backend host type from the Front Door configurations. Thank you! ![97508-image.png][1] [1]: /api/attachments/97508-image.png?platform=QnA

All you need to do is add the logic app FQDN to the AFD backend pool. Once after establishing that connection if you try to access the AFD URL, the trigger should wake your app.
Note: If the reason for deploying AFD Infront your logic app is only for exposing your app then API management would be the best fit here where it also provides other security features like AD authentication for secure access.
