Cambiar el servicio de evento

Change Event proporciona un desglose detallado de lo que cambió en tu cuenta. Cuando se informa sobre una operación de creación, se muestran todos los valores de los campos nuevos y, cuando se genera un informe sobre una operación de actualización, se muestran los valores nuevos y antiguos, lo que te brinda un panorama completo de los cambios individuales.

Además, se indica el tipo de cliente (como la API o el cliente web) que se usó para realizar el cambio, así como qué usuario lo realizó, si suponemos que la información también está visible en el historial de cambios del cliente web.

Cambiar tipos de evento

Actualmente, el servicio de evento de cambio realiza un seguimiento de los cambios de los siguientes tipos de recursos:

Tipo de recurso Valor
Anuncio AD
Grupo de anuncios AD_GROUP
Anuncio del grupo de anuncios AD_GROUP_AD
Modificador de ofertas del grupo de anuncios AD_GROUP_BID_MODIFIER
Criterio del grupo de anuncios AD_GROUP_CRITERION
Campaña CAMPAIGN
Presupuesto de la campaña CAMPAIGN_BUDGET
Criterio de campaña CAMPAIGN_CRITERION
Feed del grupo de anuncios AD_GROUP_FEED
Feed de campaña CAMPAIGN_FEED
Feed FEED
Elemento del feed FEED_ITEM
Recurso ASSET
Elemento del cliente CUSTOMER_ASSET
Elemento de la campaña CAMPAIGN_ASSET
Elemento del grupo de anuncios AD_GROUP_ASSET

Consulta

La lista de cambios debe filtrarse por fecha (el período debe estar dentro de los últimos 30 días).

La consulta también debe incluir una cláusula LIMIT que restrinja los resultados a un máximo de 10,000 filas. Si te interesa más de 10,000 resultados, toma nota de la marca de tiempo de la última entrada en el conjunto de resultados que se muestra y, luego, establece el período en la siguiente consulta para comenzar después de ese tiempo a fin de que continúe desde donde lo dejaste.

Un cambio puede tardar hasta tres minutos en reflejarse en los resultados del evento de cambio.

En el siguiente ejemplo, se muestra cómo recuperar eventos y cambiarlos, lo que incluye determinar quién realizó el cambio, qué tipo de cliente usó para realizar el cambio y los valores antiguos y nuevos de cada campo en el cambio:

Limitaciones

Es posible que un evento de cambio no incluya todas las filas del historial de cambios en el cliente web. Para obtener una vista similar al historial de cambios, usa el recurso de estado del cambio.

El recurso de evento de cambio está diseñado para desglosar los detalles de un cambio individual. Puedes recuperar datos como los valores de campo específicos que cambiaron, quién hizo el cambio y qué tipo de cliente se usó para hacer el cambio. Sin embargo, no todos los cambios que realices en tu cuenta tendrán una entrada de evento de cambio correspondiente.

Estos son algunos tipos de cliente clave que registran sus cambios para usarlos con eventos de cambio:

  • API de Google Ads
  • Cliente web de Google Ads

Los cambios realizados con la API de AdWords se excluyen de los resultados de las consultas de eventos de cambio en la API de Google Ads.
