Trigger some action in openhab from an external system, using GET method


I’m using OpenHab3. I would like to trigger an action in OpenHab, either a rule, item update or anything, from an external system. I’ve been looking at the REST api and it seems any update requires using POST. Unfortunately, the external system can only issue GET requests. Is there a workaround for this? I’d rather not create my own web server to act as a bridge.


Have a look at this thread Change state of Item based on a HttpGetRequest received by OpenHAB .
