Custom Domain only works for one Azure Function, how setup multiple functions

Question

Answer 1

Configuring custom DNS in Azure Functions:

1. Create a Function App
2. Create a function with HTTP Trigger (Make sure to select the appropriate Authorization Level) -- Use code or portal of your choice of IDE
3. Deploy your code to the functions app
4. Goto FunctionApp -->TLS Settings-->Upload your Domain certificate
5. Go to FunctionApp-->Custom DNS-->Add the mapping (You must complete recordset into your DNS pointing to the function as CNAME)
6. Complete secure binding

You can now browse to your <DNS>/api/<YOUR HTTP FUNCTION>

P.S: If you run your function in multiple regions then create a TXT record and then use a Global Load balancer such as Traffic Manager or Front Door name to map to CNAME
