Automated Alerts for code configuration -identify drop off of code

"As discussed in the management meeting on the 17/05/2017. It would be a good idea if we could setup some alerts where a customer has either not implemented Delacon code or has removed Delacon Code.

We had this system setup at Jet. Basically an email would be sent to support advising them that XYZ website is not sending any requests to our server. So if we had not received a request from the website within the last 24 hours an alert email will be sent."
