[Appointments+] Appointments+ Integrations

Hi,
Australian Skin Clinics are looking at a booking system for their 50+ clinics. They use a clinic management system called Gumnuts and would like whatever system they have to integrate with that (they mean check appointments on the Gumnuts system and push new appointments to this system). Obviously you don't have that integration built in, but would it be possible with Appointments+? Can you take a feed from REST or SOAP and are there hooks that we might be able to get to.
Thanks
Simon
