Eventos in-app

Aprende a trabajar con eventos in-app en el SDK para iOS.

Resumen General

Este documento es una guía sobre la implementación de eventos in-app en el SDK para iOS. Para ver una introducción a los eventos in-app para desarrolladores, consulta eventos in-app.

Antes de comenzar

Debes integrar el SDK.

Registro de eventos in-app

El SDK te permite registrar las acciones de los usuarios que ocurren en el contexto de tu aplicación. Estos se conocen comúnmente como eventos in-app.

The logEvent method

The logEvent method lets you log in-app events and send them to AppsFlyer for processing.

AppsFlyerLib exposes logEvent, predefined event name constants and predefined event parameter constants.

logEvent toma 3 argumentos:

- (void)logEventWithEventName:(NSString *)eventName
        eventValues:(NSDictionary<NSString * , id> * _Nullable)eventValues
        completionHandler:(void (^ _Nullable)(NSDictionary<NSString *, id> * _Nullable dictionary, NSError * _Nullable error))completionHandler;
  • The first argument (eventName) is the event name
  • The second argument (eventValues) is the event parameters NSDictionary
  • The third argument (completionHandler) is an optional completion handler (useful for Handling event submission success/failure)

📘

Nota

eventValues (second argument) must be a valid NSDictionary. For more information, see Foundation JSONSerialization.

Example: Send "add to wishlist" event

Por ejemplo, para registrar que un usuario agregó un artículo a su lista de deseos:

[[AppsFlyerLib shared]  logEvent: AFEventAddToWishlist withValues: @{
    AFEventParamPrice: @20,
    AFEventParamContentId: @"123456"
}]
AppsFlyerLib.shared().logEvent(AFEventAddToWishlist,
  withValues: [
     AFEventParamPrice: 20,
     AFEventParamContentId: "123456"
]);

In the above logEvent invocation:

Implementing in-app event definitions

Según la definición de ejemplo proporcionada en Comprender las definiciones de la estructura de eventos, el evento debe implementarse de la siguiente manera:

[[AppsFlyerLib shared]  logEvent: AFEventContentView withValues: @{
    AFEventParamContentId: <ITEM_SKU>,
    AFEventParamContentType: <ITEM_TYPE>,
    AFEventParamPrice: <ITEM_PRICE>
}]
AppsFlyerLib.shared().logEvent(AFEventAddToCart,
  withValues: [
    AFEventParamContent: <ITEM_NAME>
    AFEventParamContentId: <ITEM_SKU>
    AFEventParamPrice: <ITEM_PRICE>
]);

Handling event submission success and failure

You can pass a completionHandler to logEvent when recording in-app events. The handler allows you to define logic for two scenarios:

  • Un evento in-app registrado correctamente
  • Se produjo un error al registrar el evento in-app
[[AppsFlyerLib shared] logEventWithEventName:AFEventPurchase
        eventValues: @{
          AFEventParamRevenue: @200,
          AFEventParamCurrency: @"USD",
          AFEventParamQuantity: @2,
          AFEventParamContentId: @"092",
          AFEventParamReceiptId: @"9277"
        }
        completionHandler:^(NSDictionary<NSString *,id> * _Nullable dictionary, NSError * _Nullable error){
            if(dictionary != nil) {
                NSLog(@"In app callback success:");
                for(id key in dictionary){
                    NSLog(@"Callback response: key=%@ value=%@", key, [dictionary objectForKey:key]);
                }
            }
            if(error != nil) {
                NSLog(@"In app callback error:", error);
            }
    }];
AppsFlyerLib.shared().logEvent(name: AFEventAddToWishlist,
          values: [
             AFEventParamPrice: 20,
             AFEventParamContentId: "123456"
          ],
          completionHandler: { (response: [String : Any]?, error: Error?) in
            if let response = response {
              print("In app event callback Success: ", response)
            }
            if let error = error {
              print("In app event callback ERROR:", error)
            }
          });

En caso de que se produzca un error durante la grabación del evento in-app, se proporciona un código de error y una descripción de la cadena, como se indica en la tabla que figura a continuación.

Código del errorDescripción (NSError)
10"Event timeout. Check 'minTimeBetweenSessions' param" ("Tiempo de espera del evento agotado. Comprueba el parámetro 'minTimeBetweenSessions'")
11"Skipping event because 'isStopTracking' enabled" ("Se omite el evento porque 'isStopTracking' está activado")
40Network error: Error description comes from Android (Error de red: la descripción del error viene de Android)
41"No dev key" ("No hay clave de desarrollador")
50"Status code failure" + actual response code from the server ("Fallo del código de estado" + código de respuesta real del servidor)

Recording offline events

El SDK puede registrar los eventos que ocurren cuando no hay conexión a Internet disponible. Consulta Eventos in-app sin conexión para obtener más detalles.

Logging events before calling start

If you initialized the SDK but didn't call start, the SDK will cache in-app events until start is invoked.

Si hay varios eventos en el caché, se envían al servidor uno tras otro (sin lotes, una solicitud de red por evento).

📘

Nota

If the SDK is initialized, logEvent invocations will call SKAdNetwork's updateConversionValue even if start wasn't called or isStopped is set to true (in both SDK and S2S modes).

Registro de ingresos

af_revenue is the only event parameter that AppsFlyer counts as real revenue in the dashboard and reports.
You can send revenue with any in-app event. Use the AFEventParameterRevenue constant to include revenue in the in-app event. You can populate it with any numeric value, positive or negative.

El valor de los ingresos no debe contener comas separadoras, signos de divisas ni texto. Por ejemplo, un evento generador de ingresos debería ser similar a 1234.56.

Example: Purchase event with revenue

[[AppsFlyerLib shared] logEvent: AFEventPurchase 
withValues:@{
	AFEventParamContentId:@"1234567",
	AFEventParamContentType : @"category_a",
	AFEventParamRevenue: @200,
	AFEventParamCurrency:@"USD"
}];
AppsFlyerLib.shared().logEvent(AFEventPurchase, 
withValues: [
	AFEventParamContentId:"1234567",
	AFEventParamContentType : "category_a",
	AFEventParamRevenue: 200,
	AFEventParamCurrency:"USD"
]);

📘

Nota

No agregues símbolos de divisa al valor de los ingresos.

Configuring revenue currency

You can set the currency code for an event's revenue by using the af_currency predefined event parameter:

[[AppsFlyerLib shared] logEvent: AFEventPurchase
withValues:@{
	AFEventParamRevenue: @200,
	AFEventParamCurrency:@"USD"
}];
AppsFlyerLib.shared().logEvent(AFEventPurchase, 
withValues: [
	AFEventParamRevenue: 200,
	AFEventParamCurrency:"USD"
]);
  • El código de divisa debe ser un código ISO 4217 de 3 caracteres.
  • La divisa predeterminada es USD

Para obtener información sobre la configuración, visualización y conversión de divisas, consulta nuestra guía sobre las divisas de los ingresos.

Logging negative revenue

Puede haber situaciones en las que quieras registrar ingresos negativos. Ejemplo: un usuario recibe un reembolso o cancela una suscripción.

Para registrar ingresos negativos:

[[AppsFlyerLib shared] logEvent: @"cancel_purchase" 
withValues:@{
	AFEventParamContentId:@"1234567",
	AFEventParamContentType : @"category_a",
	AFEventParamRevenue: @-1.99,
	AFEventParamCurrency:@"USD"
}];
AppsFlyerLib.shared().logEvent("cancel_purchase", 
withValues: [
	AFEventParamContentId:"1234567",
	AFEventParamContentType : "category_a",
	AFEventParamRevenue: -1.99,
	AFEventParamCurrency:"USD"
]);

Observe lo siguiente en el código anterior:

  • El valor de ingresos está precedido por un signo de menos
  • The event name is a custom event called cancel_purchase - that's how the marketer identifies negative revenue events in the dashboard and raw-data reports

Validación de compras

AppsFlyer provides server verification for in-app purchases. The validateAndLogInAppPurchase method takes care of validating and logging the purchase event.

📘

Nota

La función heredada validateAndLogInAppPurchase se puede reemplazar por el conector del SDK de compra más nuevo y completamente automático. Para aprender a integrar el conector, consulta en Github sobre el conector del SDK de compra para iOS.

Purchase validation using validateAndLogInAppPurchase

validateAndLoginInAppPurchase toma estos argumentos:

- (void) validateAndLogInAppPurchase:(NSString *) productIdentifier,
                  price:(NSString *) price
                  currency:(NSString *) currency
                  transactionId:(NSString *) tranactionId
                  additionalParameters:(NSDictionary *) params
                  success:(void (^)(NSDictionary *response)) successBlock
                  failure:(void (^)(NSError *error, id reponse)) failedBlock;
validateAndLog(inAppPurchase: String?,
               price: String?,
               currency: String?,
               transactionId: String?,
               additionalParameters: [AnyHashable : Any]?,
               success: ([AnyHashable : Any]) -> Void)?,
               failure: ((Error?, Any?) -> Void)?)

Upon successful validation, a NSDictionary is returned with the receipt validation data (provided by Apple servers).

📘

Nota

Calling validateAndLogInAppPurchase generates an af_purchase in-app event upon successful validation. Sending this event yourself creates duplicate event reporting.

Example: Validate in-app purchase

[[AppsFlyerLib shared] validateAndLogInAppPurchase:@"ProductIdentifier" price:@"price"
    currency:@"USD"
    transactionId:@"transactionID"
    additionalParameters:@{@"test": @"val" , @"test1" : @"val 1"}
    success:^(NSDictionary *result){
      NSLog(@"Purchase succeeded And verified! response: %@", result[@"receipt"]);
    } failure:^(NSError *error, id response) {
      NSLog(@"response = %@", response);
      if([response isKindOfClass:[NSDictionary class]]) {
        if([response[@"status"] isEqualToString:@"in_app_arr_empty"]){
          // retry with 'SKReceiptRefreshRequest' because
          // Apple has returned an empty response
          // <YOUR CODE HERE>
        }

      } else {
        //handle other errors
        return;
      }
  }];
AppsFlyerLib.shared().validateAndLogInAppPurchase (
  inAppPurchase: "productIdentifier",
  price: "price",
  currency: "currency",
  transactionId: "transactionId",
  additionalParameters: [:],
  success: {
      guard let dictionary = $0 as? [String:Any] else { return }
      dump(dictionary)
    }, 
  failure: { error, result in
      guard let emptyInApp = result as? [String:Any],
      let status = emptyInApp["status"] as? String,
      status == "in_app_arr_empty" else {
      // Try to handle other errors
      return
    }     
    })

Prueba de validación de compra en el modo de entorno de pruebas

Para probar la validación de la compra mediante un entorno de pruebas, agrega el siguiente código:

[AppsFlyerLib shared].useReceiptValidationSandbox = YES;
AppsFlyerLib.shared().useReceiptValidationSandbox = true

📘

Nota

Este código debe eliminarse de tus compilaciones de producción.

Validating an in-app purchase automatically generates and sends an in-app purchase event to AppsFlyer. Its eventValues will look something like this:

{
   "some_parameter": "some_value", // from additional_event_values
   "af_currency": "USD", // from currency
   "af_content_id" :"test_id", // from purchase
   "af_revenue": "10", // from revenue
   "af_quantity": "1", // from purchase
   "af_validated": true // flag that AF verified the purchase
}
