BMC Remedy Integration

For the initial POST to their API to create the incident, does it return the Internal identifier for what was created?

LogicMonitor has utilized the ##EXTERNALTICKETID## field in other ITSM integrations (like their ServiceNow module).  You could store the internal id in that field and reference it on subsequent events related to that alert in LM.  That way you don't have to make that extra fetch-call to get translation from ##ALERTID## to whatever Remedy stored.
