Fintech push notifications are the most time-sensitive notifications on a user's phone. A fraud alert needs to open the card freeze screen instantly. A payment reminder needs to open the payment form. A price alert needs to open the asset page while the price is still relevant. Deep links make these notifications actionable.<\/p>\n\n\n\n

This guide covers push notification deep linking patterns for fintech apps. For general push notification strategy, see push notification strategy<\/a>. For fintech deep linking, see deep linking for fintech and banking apps<\/a>.<\/p>\n\n\n\n

Notification Categories<\/h2>\n\n\n\n

Security Notifications (Critical)<\/h3>\n\n\n\n

These require immediate action and should deep link to the relevant security screen:<\/p>\n\n\n\n

{\n  "title": "Suspicious activity detected",\n  "body": "Unusual login attempt from a new device in Berlin, Germany",\n  "deep_link": "https:\/\/links.finapp.com\/settings\/security",\n  "category": "security_alert",\n  "priority": "critical",\n  "sound": "alert"\n}\n<\/code><\/pre>\n\n\n\n
{\n  "title": "Card frozen",\n  "body": "Your card ending in 4589 was frozen due to suspicious activity",\n  "deep_link": "https:\/\/links.finapp.com\/cards\/CARD-456",\n  "category": "card_frozen",\n  "priority": "critical"\n}\n<\/code><\/pre>\n\n\n\n
Transaction Notifications (High)<\/h3>\n\n\n\n
{\n  "title": "Purchase: $45.00",\n  "body": "Whole Foods Market - Debit card ending in 4589",\n  "deep_link": "https:\/\/links.finapp.com\/transactions\/TXN-12345",\n  "category": "transaction",\n  "priority": "high"\n}\n<\/code><\/pre>\n\n\n\n
{\n  "title": "Direct deposit received",\n  "body": "$3,200.00 from Acme Corp",\n  "deep_link": "https:\/\/links.finapp.com\/accounts\/ACC-789\/transactions",\n  "category": "deposit",\n  "priority": "high"\n}\n<\/code><\/pre>\n\n\n\n
Payment Notifications (High)<\/h3>\n\n\n\n
{\n  "title": "Payment due tomorrow",\n  "body": "Credit card payment of $850.00 is due July 15",\n  "deep_link": "https:\/\/links.finapp.com\/payments\/make",\n  "category": "payment_due",\n  "priority": "high"\n}\n<\/code><\/pre>\n\n\n\n
{\n  "title": "Payment successful",\n  "body": "Your payment of $850.00 was processed",\n  "deep_link": "https:\/\/links.finapp.com\/payments",\n  "category": "payment_confirmed",\n  "priority": "normal"\n}\n<\/code><\/pre>\n\n\n\n
Investment Notifications (Normal)<\/h3>\n\n\n\n
{\n  "title": "AAPL hit your price target",\n  "body": "Apple Inc. reached $195.00 (+2.3%)",\n  "deep_link": "https:\/\/links.finapp.com\/stocks\/AAPL",\n  "category": "price_alert",\n  "priority": "normal"\n}\n<\/code><\/pre>\n\n\n\n
{\n  "title": "Dividend received",\n  "body": "$12.50 dividend from VTI added to your account",\n  "deep_link": "https:\/\/links.finapp.com\/portfolio",\n  "category": "dividend",\n  "priority": "normal"\n}\n<\/code><\/pre>\n\n\n\n
Engagement Notifications (Low)<\/h3>\n\n\n\n
{\n  "title": "Weekly spending summary",\n  "body": "You spent $620 this week. Tap to see the breakdown.",\n  "deep_link": "https:\/\/links.finapp.com\/transactions\/categories",\n  "category": "spending_summary",\n  "priority": "low"\n}\n<\/code><\/pre>\n\n\n\n
Handling Deep Links from Notifications<\/h2>\n\n\n\n
iOS Implementation<\/h3>\n\n\n\n
\/\/ In AppDelegate or SceneDelegate\nfunc userNotificationCenter(_ center: UNUserNotificationCenter,\n                            didReceive response: UNNotificationResponse,\n                            withCompletionHandler completionHandler: @escaping () -> Void) {\n    let userInfo = response.notification.request.content.userInfo\n\n    guard let deepLinkString = userInfo["deep_link"] as? String,\n          let deepLinkUrl = URL(string: deepLinkString) else {\n        completionHandler()\n        return\n    }\n\n    let category = userInfo["category"] as? String ?? "unknown"\n\n    \/\/ Security notifications require biometric before showing content\n    if category.hasPrefix("security") || category == "card_frozen" {\n        requestBiometric { success in\n            if success {\n                self.handleDeepLink(deepLinkUrl)\n            }\n            completionHandler()\n        }\n    } else {\n        handleDeepLink(deepLinkUrl)\n        completionHandler()\n    }\n}\n<\/code><\/pre>\n\n\n\n
Android Implementation<\/h3>\n\n\n\n
class NotificationDeepLinkReceiver : FirebaseMessagingService() {\n    override fun onMessageReceived(message: RemoteMessage) {\n        val deepLink = message.data["deep_link"] ?: return\n        val category = message.data["category"] ?: "unknown"\n        val priority = message.data["priority"] ?: "normal"\n\n        val channelId = when (priority) {\n            "critical" -> "security_channel"\n            "high" -> "transactions_channel"\n            else -> "general_channel"\n        }\n\n        val intent = Intent(Intent.ACTION_VIEW, Uri.parse(deepLink)).apply {\n            flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TOP\n        }\n\n        val pendingIntent = PendingIntent.getActivity(\n            this, 0, intent,\n            PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE\n        )\n\n        showNotification(\n            channelId = channelId,\n            title = message.notification?.title ?: "",\n            body = message.notification?.body ?: "",\n            pendingIntent = pendingIntent,\n            priority = priority\n        )\n    }\n}\n<\/code><\/pre>\n\n\n\n
Notification Channels and Priority<\/h2>\n\n\n\n
Android Notification Channels<\/h3>\n\n\n\n
Fintech apps should use separate channels for different notification types:<\/p>\n\n\n\n
fun createNotificationChannels(context: Context) {\n    val manager = context.getSystemService(NotificationManager::class.java)\n\n    \/\/ Critical: Security alerts (cannot be silenced)\n    val security = NotificationChannel("security_channel", "Security Alerts",\n        NotificationManager.IMPORTANCE_HIGH).apply {\n        description = "Fraud alerts and security notifications"\n        setBypassDnd(true)\n    }\n\n    \/\/ High: Transaction alerts\n    val transactions = NotificationChannel("transactions_channel", "Transactions",\n        NotificationManager.IMPORTANCE_DEFAULT).apply {\n        description = "Transaction confirmations and alerts"\n    }\n\n    \/\/ Normal: Account updates\n    val account = NotificationChannel("account_channel", "Account Updates",\n        NotificationManager.IMPORTANCE_LOW).apply {\n        description = "Statements, balances, and account activity"\n    }\n\n    manager.createNotificationChannels(listOf(security, transactions, account))\n}\n<\/code><\/pre>\n\n\n\n
iOS Notification Categories with Actions<\/h3>\n\n\n\n
Add actions directly to fintech notifications:<\/p>\n\n\n\n
let freezeAction = UNNotificationAction(identifier: "FREEZE_CARD",\n    title: "Freeze Card", options: [.destructive])\nlet reviewAction = UNNotificationAction(identifier: "REVIEW_ACTIVITY",\n    title: "Review Activity", options: [.foreground])\n\nlet fraudCategory = UNNotificationCategory(identifier: "fraud_alert",\n    actions: [freezeAction, reviewAction],\n    intentIdentifiers: [])\n<\/code><\/pre>\n\n\n\n
When the user taps "Freeze Card," the app deep links to the card management screen with the freeze action pre-triggered.<\/p>\n\n\n\n
Security Considerations<\/h2>\n\n\n\n
Sensitive Data in Notifications<\/h3>\n\n\n\n
Never include full account numbers, balances, or PII in push notification text:<\/p>\n\n\n\n
BAD:  "Account 1234567890 balance: $5,430.50"\nGOOD: "Account ending in 7890: new transaction"\n<\/code><\/pre>\n\n\n\n
The notification text is visible on the lock screen. The deep link opens the app where the user can see full details after authentication.<\/p>\n\n\n\n
Authentication After Notification Tap<\/h3>\n\n\n\n
Security-sensitive notifications should require authentication before showing content:<\/p>\n\n\n\n
    \n
  1. User taps notification.<\/li>\n
  2. App opens with a biometric\/PIN prompt.<\/li>\n
  3. After authentication, navigate to the deep linked screen.<\/li>\n<\/ol>\n\n\n\n
    Do not skip authentication even though the user "just tapped a notification." The phone could be in someone else's hands.<\/p>\n\n\n\n
    Rate Limiting<\/h3>\n\n\n\n
    Rate limit notifications to prevent notification fatigue and potential abuse:<\/p>\n\n\n\n
    \n\n\n\n\n\n\n\n
    Category<\/th>\nMaximum Frequency<\/th>\n<\/tr>\n<\/thead>\n
    Transaction alerts<\/td>\nEvery transaction (user-controlled)<\/td>\n<\/tr>\n
    Security alerts<\/td>\nNo limit (always send)<\/td>\n<\/tr>\n
    Payment reminders<\/td>\n1 per payment, 3 max reminders<\/td>\n<\/tr>\n
    Spending summaries<\/td>\nWeekly<\/td>\n<\/tr>\n
    Promotional<\/td>\n2-3 per week max<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n
    Measuring Notification Performance<\/h2>\n\n\n\n
    \n\n\n\n\n\n\n\n
    Metric<\/th>\nWhat It Measures<\/th>\n<\/tr>\n<\/thead>\n
    Delivery rate<\/td>\nNotifications successfully delivered<\/td>\n<\/tr>\n
    Open rate<\/td>\nNotifications tapped by the user<\/td>\n<\/tr>\n
    Deep link success rate<\/td>\nTaps that successfully opened the correct screen<\/td>\n<\/tr>\n
    Action completion rate<\/td>\nUsers who completed the intended action (e.g., made a payment)<\/td>\n<\/tr>\n
    Opt-out rate<\/td>\nUsers who disabled notifications<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n
    Track the deep link success rate separately from the open rate. If users tap notifications but do not land on the correct screen, the deep linking implementation has issues.<\/p>\n\n\n\n
    Tolinku for Fintech Notifications<\/h2>\n\n\n\n
    Tolinku<\/a> deep links work in push notification payloads. Include the Tolinku link URL as the deep_link<\/code> parameter in your notification payload. The app's Tolinku SDK handles routing to the correct screen. Configure your routes in the Tolinku dashboard<\/a>.<\/p>\n\n\n\n
