There is a few ways to call a function from the function:

  1. HTTP request - it's simple, execute a normal HTTP request to your second function. It's not recommended, because it extends function execution time and generates a few additional problems, such as the possibility of receiving a timeout, the unavailability of the service and others.

  2. Storage queues - make communication through queues (recommended), e.g. the first function (in your situation: "PUT function) can insert a message to the queue and the second function ("DELETE function") can listen on this queue and process a message.

  3. Azure Durable Functions - this extensions allows to create rich, easy-to-understand workflows that are cheap and reliable. Another advantage is that they can retain their own internal state, which can be used for communication between functions.

I wouldn't recommend trying to call the actual function directly, but you can certainly refactor the DELETE functionality into a normal method and then call that from both the DELETE and PUT functions.
