Thanks for your detailed response @Bryan-Square, very helpful.
Yes, that’s the flow we were looking at but we came across one issue, to trigger the paymentAuthorizationViewControllerDidFinish method we need to call the completion method in the didAuthorizePayment method, we are currently sending success, and then calling verify and handling the success or failure when we send the tokens to the server in the paymentAuthorizationViewControllerDidFinish method. So as far as we can tell we can’t handle the success or failure completion method on the Apple Pay controller in paymentAuthorizationViewControllerDidFinish as it has already been called to trigger this method.
Any ideas?
