I'm working on integrating Zabbix into a custom CMS solution. I have a custom media type that accesses my API in order to push alerts out to users of the CMS without setting them all up within Zabbix. I'd like to be able to allow my users to acknowledge and update event messages from the CMS and then have the trigger action update operation send out messages. The updating process currently works, but it seems like the update operation is not being called. If I update the event within the interface the update operation happens and messages are pushed out to users via the CMS API. The same custom media type works for event creation and resolution operations within the action, it just seems that calling event.acknowledge doesn't trigger the update operation via the Zabbix API. Is there separate API method to call that would call the update operation action spanish classes near me?
