ahh well that makes sense then 
1.8 api is documented here - http://xibo.org.uk/manual-tempel/en/api.html
and the 1.8 calls are documented here - http://xibo.org.uk/manual-tempel/api/
I think I’ll create some guide about API access and some example calls using Postman (which I’d recommend it’s quite great) later today - could be useful for community.
Edit - 1.8 API Introduction
