The text:
For individuals and businesses system integration use cases where the cellular delivery is insufficient, it should be possible for individuals and business to subscribe to webhook notifications, e.g. delivered as an authenticated HTTPS POST, with appropriate subscription filters and at no cost.
An example use case: In a stadium, the "crowd" will all be notified, but the business operating processes would have to be initiated manually, probably centrally in an area where the alert was NOT received. The crowd may react IMMEDIATELY, for example to exit to the car park, potentially causing bottleneck/crush issues. The business may decide that the "right" operational response for the shopping center is to:
- raise the car park barriers for the rest of the day
- put notification on the car park payment machines to state that payment is not required
- close all tills
- open all exits
- make an announcement over the tannoy (after the 10 second alert is complete)
- adjust signage
- *... etc.
To permit systems to work well with the Emergency Alerts system, the ability to subscribe to "all events requiring people to return to their homes in Reading" would put the business (and individuals) in control of the process.
