Tracking Events (Non Revenue)

Singular can collect data about in-app events to help analyze the performance of your campaigns and measure KPIs. For example, your organization may want to collect data about user logins, registrations, tutorial completions, or leveling up in a gaming app.

Singular supports a variety of standard events. These commonly used events are often supported by ad networks for reporting and optimization. Another advantage is that when you use standard event names, Singular recognizes them automatically and adds them to the Events list without you having to define them manually. We recommend using standard events whenever possible.

The list of events sent to Singular (with the accompanying attributes) should be compiled by the UA/marketing/business team based on your organization's marketing KPIs. The business team can follow the guide at How to Track In-App Events: Guide For Singular Attribution Customers.

With each event you track, you can pass various attributes. See the recommended standard attributes per event.

In your code, send events to Singular using the event or eventWithArgs methods.

Example:

Singular.event(Events.sngLogin);
Singular.eventWithArgs(eventName, {attributeName:attributeValue});
Map<String, Object> map = HashMap<String, Object>();
map ['name'] = 'John Doe';
map ['age'] = 30;
map ['isStudent'] = false;
Singular.eventWithArgs('event_Name', map);

Tracking Revenue

Sending IAP Events

To let Singular track how much revenue your app is making, send IAP events to Singular. By sending the IAP event you also allow Singular to check the event verification data and make sure it's not fraudulent.

See the following example.

Note: This code snippet requires the Flutter IAP package at https://pub.dev/packages/in_app_purchase.

import 'package:singular_flutter_sdk/singular_iap.dart';
import 'dart:io' show Platform;
            
// Parse the revenue amount and currency first
double revenue = double.tryParse(product.rawPrice.toStringAsFixed(2)) ?? 0.0;
String? currencyCode = product.currencyCode;

// Only process if both revenue is greater than 0 and currencyCode exists
if (revenue > 0 && currencyCode != null && currencyCode.isNotEmpty) {
  if (Platform.isIOS) {
    singularPurchase = new SingularIOSIAP(
      revenue,
      currencyCode,
      purchase.productID,
      purchase.purchaseID,
      purchase.verificationData.serverVerificationData
    );
  }
              
  else if (Platform.isAndroid) {
    singularPurchase = new SingularAndroidIAP(
      revenue,
      currencyCode,
      purchase.verificationData.serverVerificationData,
      purchase.verificationData.localVerificationData
    );
  }
              
  Singular.inAppPurchase(eventName, singularPurchase);
}

Alternative Method: Sending Custom Revenue Events

Singular also offers the option of reporting revenue by just sending a custom revenue event with a name and a revenue amount. Note that this method does not share the purchase receipt with Singular and therefore, does not allow Singular to verify that it's a legitimate event.

For example:

Singular.customRevenue("MyCustomRevenue", "USD", 5.50);
Map<String, Object> map = HashMap<String, Object>();
map ['name'] = 'John Doe';
map ['age'] = 30;
map ['isStudent'] =false;
Singular.customRevenueWithAttributes('MyCustomRevenue','USD', 20, map);

Hybrid Event Tracking (Advanced)

Singular recommends sending all events and revenue through the Singular SDK integrated into your app. However, Singular can collect events and revenue from other sources.

Any event NOT sent from the Singular SDK must comply with Singular's Server-to-Server Event documentation requirements and provide the matching device identifier to correctly attribute an event.
