Today’s post will be on how to expose an API hosted via an Azure function via Azure API management. So what are we going to configure today? We’ll expose the function API externally. The “user” (or client app) will authenticate with API management via a “subscription key“. Afterwards API management will call the back-end function, where it will authenticate via the function authentication code.
So let’s go to our function …
Where we’ll grab the “function URL”. This contains the query parameter “code” which uses the function key as authentication.
