[Observium] Generic Notification API SMS

Hello,

Is there some method how we can set notification via generic HTTP GET ?

We have SMS provider and there is example of GET command

https://%7Bbase_url%7Dhttps://dev.infobip.com/getting-started/base-url/sms/1/text/query?username=myUsername&password=myPassword&to=41793026727,41793026834&text=Message text

Where for example variable "text" will be Environment Variable from Observium like

text=OBSERVIUM_ALERT_STATE, OBSERVIUM_DEVICE_HOSTNAME, OBSERVIUM_DEVICE_LOCATION

Thank you

Tom
