Anuncios de destinos: eventos

Los anuncios de destino usan cuatro eventos. Cada evento tiene un conjunto de parámetros (puedes ver la lista completa en los detalles de parámetros de eventos). Usa el píxel de Meta en tu sitio web y los eventos de la app para celulares en tu app para Android y app para iOS. Obtén más información sobre los eventos estándar y los eventos personalizados.

Píxel de Facebook (para sitios web)

En esta guía, se asume que ya tienes instalado el píxel de Facebook. Si no es así, consulta Usar la API de marketing con el píxel.

Asegúrate de que el código base del píxel ya esté cargado cuando actives un evento. Si usas un administrador de etiquetas, asegúrate de incluir la etiqueta que contiene el código del píxel en cada página. Esta etiqueta debe aparecer antes de la que contiene el código de evento del píxel. Usa el asistente para píxeles de Facebook a fin de validar la implementación del píxel.

Detalles de los parámetros de eventos

En el celular, los nombres de los parámetros no son iguales que en el píxel de Meta. A menudo, tienen fb_ antepuesto, pero hay algunas excepciones, como content_ids, que varía a fb_content_id, y value, que es _valueToSum.

Cuando envíes varios valores, por ejemplo, con content_ids o content_type, proporciona una matriz de valores en formato JSON: '["value1", "value2"]'. No concatenes los valores con una coma.
