Pay By Bank returnUrl format

[Czarczynski]

I am facing issue with Pay By Bank method where external bank app is being opened and then it redirects to my app.

We use session flow.

What should returnUrl format look like?

When I have myappid:///payment/providers attached, it comes with query params sessionId and redirectResult. But non of listeners (onSubmit, onAdditionalData, onError, onComplete) is called. And on top of that is web view screen that shows message presented on the screenshot. As said I should be able to close it and further steps should be taken by listeners but they are not.

For now I am testing it with iOS platform

Used packages:
expo 53
@adyen/react-native 2.6.1
expo-router 5.0.7

Hey @Czarczynski

Thank you for reaching out.

Would be interesting to know if same behaviour is observed on Android.

When I have myappid:///payment/providers attached, it comes with query params sessionId and redirectResult.

To confirm my understanding: the redirect from the issuer's bank back to our app is successful (the bank app closes and a breakpoint in AppDelegate is hit).

Could you please confirm if the [ADYRedirectComponent applicationDidOpenURL:url] (or RedirectComponent.applicationDidOpen) method is called?

Yes, app opens successfully

Could you please confirm if the [ADYRedirectComponent applicationDidOpenURL:url] (or RedirectComponent.applicationDidOpen) method is called?

I tried put breakpoint on return line and before that I was trying to log some information via NSLog. But nothing shown nether breakpoint nor NSLog :/

I was trying to log some information via NSLog

Could you try something like:

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
        var result = RedirectComponent.applicationDidOpen(from: url) ? "success" : "failure"
        print("URL \(result ? "success" : "failure" ): \(url)")
        return result
}

As far as I use expo prebuild I have no file UIApplicationDelegate. I tried to search throughout whole ios directory text RedirectComponent.applicationDidOpen(from: url) but only one has been found and it was in readme file and RedirectComponentProxy.

Previews logging and breakpoint I put inside ADYRedirectComponent.m file.

Indeed, your iOS is on Objc-c, not swift. Sorry for confusion.
Something like this:

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
  BOOL result = [ADYRedirectComponent applicationDidOpenURL:url];
  NSLog(@"URL %@ : %@", result ? @"success" : @"failure", [url absoluteString]);
  return result;
}

The result of this log is:

URL success: myappid:///payment/providers?sessionId=[sessionId]&redirectResult=[sedirectParams]

But to be precise I needed to replace previous application's override in AppDelegate(written in swift after all). Previous implementation was associated with Firebase.

  public override func application(
    _ app: UIApplication,
    open url: URL,
    options: [UIApplication.OpenURLOptionsKey: Any] = [:]
  ) -> Bool {
// @generated begin @react-native-firebase/auth-openURL - expo prebuild (DO NOT MODIFY)
    if url.host?.lowercased() == "firebaseauth" {
      // invocations for Firebase Auth are handled elsewhere and should not be forwarded to Expo Router
      return false
    }
// @generated end @react-native-firebase/auth-openURL
    return super.application(app, open: url, options: options) || RCTLinkingManager.application(app, open: url, options: options)
  }
