Flow

Prepare

1. Make sure issuer app has been installed
2. Setup the URL scheme in the Info.plist of example project
3. Issuer App will launch your App with tspPushToken and cancelUrl
4. Parse TspPushToken and cancelUrl from intent data
5. Send Push Token API to Tappay server
6. You will get a suceess response with cardKey and cardToken
7. You may get more card information by Card Metadata API if you want

Usage

If the setup and usage of issuer bank app has already finished

Objective C

1. Get push token in AppDelegate or SceneDelegate

// AppDelegate
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
    // Parsing the url by any method which could return parameters
    NSArray *queryItems = [GlobalFunction queryParameter:url];
    // Post the push token and cancel url to observer
    [[NSNotificationCenter defaultCenter] postNotificationName:@"TSP_Push_Token" object:queryItems];
    return true;
}

// SceneDelegate
- (void)scene:(UIScene *)scene openURLContexts:(NSSet<UIOpenURLContext *> *)URLContexts {
    NSURL * url = [[[URLContexts allObjects] firstObject] URL];
    // Parsing the url by any method which could return parameters
    NSURL * url = [[[URLContexts allObjects] firstObject] URL];
    NSArray *queryItems = [GlobalFunction queryParameter:url];
    // Post the push token and cancel url to observer
    [[NSNotificationCenter defaultCenter] postNotificationName:@"TSP_Push_Token" object:queryItems];
}

2. Register observer to get push token and post push tokenize request

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenGet:) name:@"TSP_Push_Token" object:nil];
}

- (void)tokenGet:(NSNotification *)notification {
    NSString *pushToken = [notification object];
    if (pushToken.length > 0) {
        [self pushTokenizeWithToken:pushToken successCallback:^(NSDictionary *result) {
            // Do something here if request succeed
        } failureCallback:^(NSDictionary *result,  NSError *error) {
            // Do something here if request failed
        }];
    }
}

- (void)pushTokenizeWithToken:(NSString *)token
              successCallback:(void (^)(NSDictionary *result))successCallback
              failureCallback:(void (^)(NSDictionary *result,  NSError *error))failureCallback{
    ...
    
    NSDictionary *parametersDict = @{@"partner_key":yourPartnerKey,
                                     @"tsp_push_token":token};
                                        
    ...
}

Swift

1. Get push token in AppDelegate or SceneDelegate

// AppDelegate
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    // Parsing the url by any method which could return parameters
    let queryItems = URLComponents(string: url.absoluteString)?.queryItems
    // Post the push token and cancel url to observer
    NotificationCenter.default.post(name:NSNotification.Name.init("TSP_Push_Token"), object: queryItems, userInfo: nil)
    return true
}

// SceneDelegate
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
    if let url = URLContexts.first?.url {
        // Parsing the url by any method which could return parameters
        let queryItems = URLComponents(string: url.absoluteString)?.queryItems
        // Post the push token and cancel url to observer
        NotificationCenter.default.post(name:NSNotification.Name.init("TSP_Push_Token"), object: queryItems, userInfo: nil)
    }
}

2. Register observer to get push token and post push tokenize request

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    NotificationCenter.default.addObserver(self, selector: #selector(tokenGet(notification:)), name: NSNotification.Name.init("TSP_Push_Token"), object: nil)
}

@objc func tokenGet(notification : NSNotification) {
    let pushToken = notification.object as! String
    if pushToken.count > 0 {
        pushTokenizeWithToken(token: pushToken) { result in
            // Do something here if request succeed
        } fail: { result,error in
            // Do something here if request failed
        }
    }
}

private func pushTokenizeWithToken(token: String ,success: @escaping (_ result: Dictionary<String, Any>) -> Void ,fail: @escaping (_ result:Dictionary<String, Any>, _ error:Error) -> Void) {
    
    ...
    
    let parametersDict = ["partner_key":yourPartnerKey,"tsp_push_token":token]
    
    ...
    
}
