Evento de cambio 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 campo nuevos, y cuando se informa sobre una operación de actualización, se muestran los valores nuevos y los anteriores, 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 el usuario que lo hizo, siempre que esa información también sea visible en el historial de cambios del cliente web.
Cambiar los tipos de eventos
Consulta la lista de tipos de recursos de ChangeEventResourceType.
Consulta
La lista de cambios debe filtrarse por fecha. El período debe ser 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 interesan más de 10,000 resultados, toma nota de la marca de tiempo de la última entrada del conjunto de resultados que se muestra y, luego, establece el período en la siguiente consulta para que comience después de ese momento y continúe desde donde te quedaste.
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 de cambio y procesarlos, incluso determinar quién realizó el cambio, qué tipo de cliente usó para realizarlo y los valores anteriores 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 change status.
El recurso de evento de cambio está diseñado para desglosar los detalles de un cambio individual. Puedes recuperar datos, como valores de campos específicos que cambiaron, quién realizó el cambio y qué tipo de cliente se usó para realizarlo. Sin embargo, no todos los cambios en tu cuenta tendrán una entrada de evento de cambio correspondiente.
Estos son algunos tipos de clientes clave que sí registran sus cambios para usarlos con eventos de cambio:
- API de Google Ads
- Cliente web de Google Ads
