Yeah it works, thats not my problem, the Problem is, it uses the default opsgenie API, not the one you could set up in opsgenie (under Teams → Integrations → Check_MK), where you could set rules for the alerts.
https://api.eu.opsgenie.com/v1/json/checkmk you can’t use this url, where the Integration for Check_MK from Opsgenie is, it only uses the default api.
