Hi, I'd like to get/make(plugin?)/hire/create the payment system inside the APEX app (cart, PayPal, credit card). I've got some issues here: https://www.paypal.com/apex/home
Users should choose an app to buy, put it into the cart, pay, and the app should download automatically (this last state is my concern). Or they could get memberships, or tickets, etc.
Does anyone know any solution?
Thanks
