Cambia evento

Evento modifica fornisce una suddivisione dettagliata di ciò che è cambiato nel tuo account. Quando si esegue il reporting su un'operazione di creazione, vengono restituiti tutti i nuovi valori dei campi, mentre quando si esegue il reporting su un'operazione di aggiornamento vengono restituiti sia i valori nuovi che quelli precedenti, fornendo un quadro completo delle singole modifiche.

Viene indicato inoltre il tipo di client (ad esempio API o client web) utilizzato per apportare la modifica e l'utente che ha apportato la modifica, supponendo che le informazioni siano visibili anche nella cronologia delle modifiche del client web.

Modificare i tipi di evento

Vengono monitorati i seguenti tipi di risorse:

Tipo di risorsa Valore
Annuncio AD
Gruppo di annunci AD_GROUP
Annuncio del gruppo di annunci AD_GROUP_AD
Modificatore offerta per gruppo di annunci AD_GROUP_BID_MODIFIER
Criterio del gruppo di annunci AD_GROUP_CRITERION
Priorità CAMPAIGN
Budget della campagna CAMPAIGN_BUDGET
Criterio campagna CAMPAIGN_CRITERION
Feed del gruppo di annunci AD_GROUP_FEED
Feed campagna CAMPAIGN_FEED
Feed FEED
Elemento del feed FEED_ITEM
Asset ASSET
Asset del cliente CUSTOMER_ASSET
Asset della campagna CAMPAIGN_ASSET
Asset del gruppo di annunci AD_GROUP_ASSET

Query

L'elenco delle modifiche deve essere filtrato in base alla data. L'intervallo di date deve rientrare negli ultimi 30 giorni.

La query deve includere anche una clausola LIMIT che limita i risultati a un massimo di 10.000 righe. Se ti interessano più di 10.000 risultati, prendi nota del timestamp dell'ultima voce nel set di risultati restituito, poi imposta l'intervallo di date per la query seguente in modo che inizi una data successiva per continuare da dove avevi interrotto.

Possono essere necessari fino a tre minuti prima che la modifica venga riportata nei risultati dell'evento di modifica.

L'esempio seguente mostra come recuperare gli eventi di modifica ed elaborarli, nonché determinare chi ha apportato la modifica, il tipo di client utilizzato per apportare la modifica e i valori vecchi e nuovi di ogni campo nella modifica:

Limitazioni

Un evento di modifica potrebbe non includere tutte le righe della cronologia delle modifiche nel client web. Per una visualizzazione simile alla Cronologia delle modifiche, utilizza la risorsa stato delle modifiche.

La risorsa evento di modifica ha lo scopo di visualizzare in dettaglio le specifiche di una singola modifica. Puoi recuperare dati quali valori specifici dei campi che sono stati modificati, chi ha apportato la modifica e quale tipo di client è stato utilizzato per apportare la modifica. Tuttavia, non tutte le modifiche al tuo account avranno una voce di evento di modifica corrispondente.

Tra i tipi di client chiave che registrano le modifiche da utilizzare con gli eventi di modifica ci sono:

  • API Google Ads
  • Client web Google Ads
