Hi, Please refer the info graphic . I'm an issuer Bank App, who wants to add a card to phone's Digital Wallet. When I hit add to Apple or Google wallet, my API call goes to a Token Requester server and then to Token Service provider. In this process, I do get a JWT token back, but when I try to add token to Digital Wallet, I always get the message "The pass cannot be read because it is not valid". So few question: Is there a way to debug the token that is received by the app? Is there any kind of API console that I can look to see what is happening and why the pass is not valid? I, being the Issuer Bank App, a Token Service Requester and A Token Service Provider, who should be communicating with Apple servers? Are there any documents that explicitly shows (example) the flow of adding a credit card to Digital Wallet from iOS perspective? Any other help is appreciated. On my end, I have done this: public void AddToDeviceAsync(string data) { try { var dataArray = Encoding.UTF8.GetBytes(data); if (data.Length > 0) { if (PKAddPassesViewController.CanAddPasses && PKPassLibrary.IsAvailable) { _nsData = NSData.FromArray(dataArray); ObjCRuntime.Class.ThrowOnInitFailure = false; _pkPass = new PKPass(_nsData, out NSError e); if (!string.IsNullOrWhiteSpace(e?.LocalizedDescription)) { UserDialogs.Instance.AlertAsync(e.LocalizedDescription, AppResources.Alert); return; } if (!PkLibrary.Contains(_pkPass)) { var controller = new PKAddPassesViewController(_pkPass); var rootViewController = UIApplication.SharedApplication.Delegate.GetWindow().RootViewController; if (rootViewController != null) { var topController = TopViewControllerWithRootViewController(rootViewController); topController?.PresentViewController(controller, true, null); } } else { UserDialogs.Instance.AlertAsync(AppResources.Pass_Already_Present, AppResources.Alert); } } } else { UserDialogs.Instance.AlertAsync(AppResources.Invalid_Pass_Data, AppResources.Alert); } } catch (Exception e) { UserDialogs.Instance.AlertAsync(e.Message, AppResources.Alert); } }
