The ability to create custom integrator flows is one of my favorite things about this product, it's just so easy! I wish there was more documentation available in our language/culture but their support team are really great at helping you out with that too :) We have been able build some pretty complex integration solutions using flow builder which has saved us loads time over building them ourselves or getting someone else do - we're now looking into doing API Connections instead because they've got such an amazing system built around those already!!
