It appears that RegisterAlertEndpoint is defined on a per-account basis, according to this troubleshooting interface flightaware.com/commercial/flightxml/send.rvt .
Can you confirm this is correct and that alert endpoints are not implemented on a per-key basis?
If this is indeed correct, is it on the roadmap to review this functionality?
The issue is that if I have 3 applications that use 3 distinct keys, I cannot have 3 endpoints. I must implement a common gateway for applications to pub/sub to FlightAware, which adds additional and unnecessary infrastructure to my project.
