* Collect the money.
* Send a notification back to the API user (the external developer).
    * This will be done by sending a POST request (from *your API*) to some *external API* provided by that external developer (this is the "callback").

## The normal **FastAPI** app { #the-normal-fastapi-app }

Let's first see how the normal API app would look like before adding the callback.

func isHostIP(ipAddress string) bool {
	host, _, err := net.SplitHostPort(ipAddress)
	if err != nil {
		host = ipAddress
	}
	// Strip off IPv6 zone information.
