How to throw a back flip on a snowboard-what i should do to prepare for it where should i do it all that stuff?

I am 13 and I really want to throw a backflip on my snowboard...i can 180 and indy grab and stuff but i do parkour and freerunning so it seemed like the flips would be some what easy for me. I can do a standing backflip, backflip off of a platform, wallflip, and all that stuff but i really want to know what a snowboard backflip is like and if im ready so please everyone hit me up and tell me...thanks in advance
