openHAB REST API and Android App Beacon Scanner

Dear Community,

I want to use bluetooth beacons for indoor localization. On my Android phone I got the app Beacon Scanner. This app is able to store an endpoint for logging, i.e. all 30 seconds I got the distance between my android device and the bluetooth beacon. Now, I want to use this functionality to communicate to openHAB REST API.

Anyway I got no idea what endpoint I need to pick, because I did not know if there is a “generic” REST PUT endpoint, which will trigger a corresponding rule and make the incoming JSON string readable in this rule - how do I achieve this goal? Thanks in advance.

Best regards,
