I am using WL Twilio service connect here:
https://reference.wolfram.com/language/ref/service/Twilio.html
I have tested it pretty thoroughly. Everything works great.
However, one big problem. How do we set a callback URL? When you send an SMS, chances are the recipient will respond. So, Twilio needs a URL of where to deliver that response.
How do I create an API endpoint that can receive that reply so I can answer it again?
I have created a PHP script that can receive the queries, ping my Instant API, and reply, but this causes too much latency. I want to use a purely end-to-end WL solution.
