itinerary creator interface into Divi website

Question

how to implement an itinerary creator interface e.g. the travefy API into a divi wordpress website ? , are there API's out there that would allow an itinerary creator interface that uses the drag and drop feature to be implemented in a divi wordpress website, if so which ones ? or is it easier to use some form of divi extension if so which one ? Detourons itinerary creator interface is a good example of what i am looking for. Detouron interface

I tried using the travefy API but apparently you can use their itinerary automation api with divi
