Is there anyone that has implemented PayPal into their Xamarin project? Ihave tried everything, but can't seem to get it working. I want to pass PayPal the Credit Card ID, then do a DirectPayment or ExpressPayment. I don't want the user to enter their details manually, in order to avoid PCI issues. I just want to save their Credit Card ID upon registering on my app. Any hints/samples/advise would be appreciated.
