I have a website running on Azure Web App. This website provides a profile page to its users. The users are looking to point their custom domains to their respective profile page. I want to minimize the manual steps to achieve this. For every custom domain, I need to add that manually to Azure Web app and also need to verify the ownership via TXT record. This could be fine for a small number of custom domains but when you have 100s of such users, it just becomes a blocker.
Is there any way I could somehow let any custom domain pointed to my website work without needing to add the domain record on Azure portal and having to verify ownership?
I wonder if Azure DNS can help me achieve my goal in anyway.
