      This caused a few issues:
      * Ports are required in Istio, but not in Kubernetes. This can result in broken traffic if ports are not configured as Istio expects, despite them working without Istio.
      * Ports not declared as `HTTP` would match *all* traffic on that port, making it easy to accidentally send all traffic on a port to the wrong place.

The user of your API (an external developer) will create an invoice in your API with a POST request.

Then your API will (let's imagine):

* Send the invoice to some customer of the external developer.
* Collect the money.
* Send a notification back to the API user (the external developer).
