Google Analytics fornisce report sugli eventi che ti aiutano a capire
in che modo gli utenti interagiscono con la tua app. Con Cloud Functions (1ª gen.), puoi
accedere agli eventi di conversione registrati da dispositivi Apple e Android
e attivare funzioni in base a questi eventi.
Attiva una funzione Google Analytics
Cloud Functions supporta Google AnalyticsAnalyticsEvent.
Questo evento viene attivato ogni volta che l'attività dell'utente genera un evento di conversione.
Ad esempio, potresti scrivere una funzione che
si attiva quando viene generato l'evento in_app_purchase, a indicare che è stato effettuato un
acquisto in-app.
Devi specificare l'evento Analytics che
vuoi attivare la tua funzione utilizzando il
metodo functions.analytics.event() e gestire l'evento all'interno del
gestore di eventi onLog():
Con ogni evento Analytics, hai accesso a tutti i parametri e le proprietà utente pertinenti. Questi includono informazioni sull'utente, sul
dispositivo, sull'app e informazioni geografiche per l'evento.
Per l'elenco completo di parametri e proprietà utente, consulta il riferimento
functions.analytics.
Per una funzione attivata dall'acquisto, come illustrato in
questo esempio,
potresti voler accedere agli attributi utente, come la lingua dell'utente e il
valore dell'evento (valueInUSD).
Questo secondo attributo consente alla funzione di esempio di verificare se si tratta di un
evento di conversione di alto valore, in modo da inviare un coupon di valore superiore ai clienti di valore.

You can specify which events are conversion events in the [Events](//console.firebase.google.com/project/_/analytics/events) tab of the Firebase console **Analytics** pane.\n| **Note:** Cloud Functions for Firebase (2nd gen) does not provide support for the events and triggers described in this guide. Because 1st gen and 2nd gen functions can coexist side-by-side in the same source file, you can still develop and deploy this functionality together with 2nd gen functions.\n\nTrigger a Google Analytics function\n\nCloud Functions supports the Google Analytics\n[`AnalyticsEvent`](/docs/reference/functions/firebase-functions.analytics.analyticsevent).\nThis event is triggered whenever user activity generates a conversion event.\nFor example, you could write a function that\ntriggers when the `in_app_purchase` event is generated, indicating that an\nin-app purchase has occurred.\nYou must specify the Analytics event that\nyou want to trigger your function using the\n[`functions.analytics.event()`](/docs/reference/functions/firebase-functions.analytics.analyticsevent)\nmethod, and handle the event within the\n[`onLog()`](/docs/reference/functions/firebase-functions.analytics.analyticseventbuilder#analyticsanalyticseventbuilderonlog)\nevent handler:\n\n\u003cbr /\u003e\n\n```gdscript\nexports.sendCouponOnPurchase = functions.analytics.event('in_app_purchase').onLog((event) =\u003e {\n // ...\n});\n```\n\n\u003cbr /\u003e\n\nAccess event attributes\n\nWith each Analytics event, you have access to all relevant\nparameters and user properties. These include information about the user, the\ndevice, the app, and geographical information for the event.\nFor the complete list of parameters and user properties, see the\n[`functions.analytics`](/docs/reference/functions/firebase-functions.analytics) reference.\n\nFor a purchase-triggered function as illustrated in\n[this sample](https://github.com/firebase/functions-samples/tree/main/Node-1st-gen/coupon-on-purchase),\nyou might want to access user attributes such as the user's language and the\nevent's value ([`valueInUSD`](/docs/reference/functions/firebase-functions.analytics.analyticsevent#analyticsanalyticseventvalueinusd)).\nThis second attribute allows the sample function to test whether this is a\nhigh-value conversion event, in order to send a higher-value coupon to valuable customers.\n\n\u003cbr /\u003e\n\n```gdscript\n/**\n * After a user has completed a purchase, send them a coupon via FCM valid on their next purchase.\n */\nexports.sendCouponOnPurchase = functions.analytics.event('in_app_purchase').onLog((event) =\u003e {\n const user = event.user;\n const uid = user.userId; // The user ID set via the setUserId API.\n const purchaseValue = event.valueInUSD; // Amount of the purchase in USD.\n const userLanguage = user.deviceInfo.userDefaultLanguage; // The user language in language-country format.\n\n // For purchases above 500 USD, we send a coupon of higher value.\n if (purchaseValue \u003e 500) {\n return sendHighValueCouponViaFCM(uid, userLanguage);\n }\n return sendCouponViaFCM(uid, userLanguage);\n});https://github.com/firebase/functions-samples/blob/c4fde45b65fab584715e786ce3264a6932d996ec/Node-1st-gen/coupon-on-purchase/functions/index.js#L23-L41\n```\n\n\u003cbr /\u003e\n\nNext steps\n\nTo learn more about handling Analytics events in Cloud Functions,\nsee the [Google Analytics documentation](/docs/analytics) and the\n[`functions.analytics`](/docs/reference/functions/firebase-functions.analytics) reference,\nand try running the code sample\n[coupon-on-purchase](https://github.com/firebase/functions-samples/tree/main/Node-1st-gen/coupon-on-purchase)."]]
