Hey, I am with RentPost | Online Property Management Software and we offer online property management software to our clients which offers many types of integration.

I was wondering if Zimbra supports an API or any integration methods for external application access. Or, does Zimbra tie into any other online platforms like google calendar/contacts/gmail, etc? We'd like to explore the option of integration with Zimbra, particularly with regards to contacts/calendar integration. Currently, we're working on google integration, but looking at a list of other integration partners as well.
