Hello,
Following this piece of documentation it appears that we can get opdata through the trigger object :
https://www.zabbix.com/documentation/current/manual/api/reference/trigger/object
But the trigger.get reference doesn't mention expandOpdata Flag :
https://www.zabbix.com/documentation/current/manual/api/reference/trigger/get
At the moment we could get the data from Operationnal but macros are not expanded.
Thanks in advance,
