Geofence events trigger to external app

Hello, i easily installed traccar few months ago on my synology and i am very happy, i have a tracker in my car and i can see it without any problem. Db is a MariaDb running on the same synology. Even if i am not really familiar with Java i could handle very easily all the process thanks to the documentation.
I am now struggling to understand which is the best strategy to connect the in/out geofence events to another application (still running on the same server): i would like to inform my openhab system about presence of the device in a specific geofence area.
Openhab is quite flexible, i could call a rest api to switch the status (somethink like "curl -X PUT --header "Content-Type: text/plain" --header "Accept: application/json" -d "ON" "http://127.0.0.1:8080/rest/items/mycar/state" ") or i could set an MQTT item to link to mycar state.
What do you suggest? Which is the best strategy to study to create this link?
Thank you

You can write your own event notification handler:

In additio to the official documentation Anton links to, you may find some usable bits of information at https://jpmens.net/2018/09/14/position-and-event-forwarding-from-traccar/

Hello, thanks for your sharing.
I implemented easily an event forward to a php script which decode the json content and in case the device id and geofence id are matching, call the rest api PUT in openhab.
Thank you again

Could you share your solution?
