Hehehe, if you know what you're doing there's little stopping you from leveraging our APIs besides for the standard mechanisms. What I will say is if you abuse the API or find any gaps which allow you to create unexpected orders, you'll be spotted very VERY (emphasis here) quickly, and your mobile number will receive a lifetime ban faster than you can say, "no more Sixty60 deliveries for me." XD
I would also like to mention, this system is massively feature heavy. This results in a highly complex system of intertwined interactions needed for you to do seemingly simple things. So, best of luck to you. Personally, I would say that if you're still left wanting from the features contained in the app, then you probably haven't spent enough time exploring the app. Also, good luck with maintenance.
