API integration between cloud apps

We are currently setting up a new job management system for our business - E-Works Manager - And are equally setting up an online customer booking system through SimplyBook.me. We need these to systems to directly connect to each other so that bookings made or being made, will reflect the live schedule available from our job management system.
